| Here's an interesting theory on evolution that I found: The Crazy Part: The part where the family tree of every living creature on Earth collides at a single point on a single day in the past, making you related to Hitler as well as every insect you?ve ever killed.. What It Says: We?re all familiar with the basics of evolution: that a munificent monkey-goddess birthed us all from Her banana-scented womb. But there are some lesser-discussed implications of natural selection that are just plain weird. For one, scientists have concluded that around 140,000 years ago in Kenya, there lived a woman called Mitochondrial Eve (cavemen had weird names), so named because today, every living human on Earth has her mitochondrial DNA in their body (cavemen were also prescient). And only 3,000 years ago lived a person known as the Most Recent Common Ancestor, who, through exponential growth of the family tree, is the ancestor of every single person on Earth. And did you know that, based on the same principles (and a lot of rape), Genghis Kahn has over 16 million descendants? Who?s your Daddy now?! So What Does This Do For Me? Well, for one, you can rest assured than anyone you ever have sex with in your entire life is at least your distant, distant cousin. So that?s nice. And if you?re really a nut for genealogy, why not trace your heritage back to the Last Universal Ancestor, the single-celled organism who, about 4 billion years ago, decided to go ahead and give rise to every living creature that will ever exist on the face of the Earth? Talk about a pimp. In essence, the whole of life on the planet can be considered one long, unbroken chemical reaction that is still resolving itself, like the foam flowing out of a science fair volcano. Wait, It Gets Worse: The genetic chaos continues. The Endosymbiotic Theory says that the mitochondria in our bodies, without which we couldn?t live, let alone write snide humor articles, was at one point a separate organism that invaded our cells and set up camp. They formed a symbiotic relationship so beneficial that we?ve never booted them out. Furthermore, large chunks of the human genome are thought to be ancient retroviruses that managed to transcribe themselves into our DNA and have spent the remainder of their days happily clambering up and down our nucleotides like the McDuck children on a mansion banister. Basically your cells are millions of individual organisms, all huddled together in a you-shaped beehive. Now see how long you can go before wanting to shower. And lastly, a thought for the right-wingers out there: At some point half of you was an egg in your Mother?s womb. That egg existed in her body from the day she was born. And a long, long time ago, she too was an egg in her Mother?s womb, who had that egg ready for use from the moment she squirmed out of your Great Grandma?s nethers. The point being, technically speaking, there?s no break in the chain of existence, no time when you are not a life form of at least the most rudimentary sort. Your family, at least on your Mother?s side, could theoretically be considered an immortal, constantly-regenerating organism. Of course that would make men, whose sperm has to be created years after the moment of birth, just disposable donors here to fuel the everlasting fire of womanhood. You go girls!

| Nuclear Energy: Myth No. 1 "Nuclear Power Isn't a Safe Solution" In a recent national poll, 72 percent of respondents expressed concern about potential accidents at nuclear power plants. Some opinion-makers have encouraged this trepidation: Steven Cohen, executive director of Columbia University's Earth Institute, has called nuclear power "dangerous, complicated and politically controversial." During the first six decades of the nuclear age, however, fewer than 100 people have died as a result of nuclear power plant accidents. And comparing modern nuclear plants to Chernobyl—the Ukrainian reactor that directly caused 56 deaths after a 1986 meltdown—is like comparing World War I fighter planes to the F/A-18. Newer nuclear plants, including the fast reactor now being developed at Idaho National Laboratory (INL), contain multiple auto-shutoff mechanisms that reduce the odds of a meltdown exponentially—even in a worst-case scenario, like an industrial accident or a terrorist attack. And some also have the ability to burn spent fuel rods, a convenient way to reuse nuclear waste instead of burying it for thousands of years. Power sources such as coal and petroleum might seem safer than nuclear, but statistically they're a lot deadlier. Coal mining kills several hundred people annually—mainly from heart damage and black lung disease, but also through devastating accidents like the April mine explosion in West Virginia. The sublethal effects of coal-power generation are also greater. "The amount of radiation put out by a coal plant far exceeds that of a nuclear power plant, even if you use scrubbers," says Gerald E. Marsh, a retired nuclear physicist who worked at Argonne National Laboratory. Particulate pollution from coal plants causes nearly 24,000 people a year to die prematurely from diseases such as lung cancer. Petroleum production also has safety and environmental risks, as demonstrated by the recent oil spill in the Gulf of Mexico. INL nuclear lab's deputy associate director, Kathryn McCarthy, thinks the industry can overcome its stigma. "It's been a long time since Chernobyl and Three Mile Island," McCarthy says, "and people are willing to reconsider the benefits of nuclear energy." Nuclear plants emit only a tiny fraction of the carbon dioxide that coal plants do, and a few hundred nuclear facilities could potentially supply nearly all the energy the United States needs, reducing our dependence on fossil fuels. | 2010-07-15 23:41:00 Author: Weretigr Posts: 2105 |
| Nuclear power is such a unique source of energy. It's clean but it's dangerous... Well, if the facilities are safe, nothing to worry about... | 2010-07-15 23:46:00 Author: gdn001 Posts: 5891 |

| I'm pretty darn sure there's other life out there! I can't see why not? | 2010-07-16 00:06:00 Author: Alec Posts: 3871 |
| I'm pretty darn sure there's other life out there! I can't see why not? For me it's OBVIOUS there's life out there. The chances of having on our own galaxy are already noticeable, and if you add all the other galaxies into the equation then... Problem is: Communication | 2010-07-16 00:10:00 Author: gdn001 Posts: 5891 |
| I believe there's other life out there in a different solar system. They could be adapted to different things than we are. Carbon Dioxide for example. There could be a civilization either like ours, stronger and more evolved than ours or nothing close to as good as ours. I however don't believe in heaven, hell or any god. I am an atheist and believe it's the realistic way to believe as religion is fairytales and supernatural and cause too many wars and arguements.

| Sorry if this has been brought up. Who has been watching Morgan Freemans Through the Wormhole? 2 guys think that our galaxy, every trillion years, collides with another galaxy and makes the big bang happen. If this is true, then there was life before life before life before life and so on and so forth. | 2010-07-16 05:35:00 Author: AbstractFlesh  Posts: 837 |

If this is true, then there was life before life before life before life and so on and so forth. We have done quite a few theories on "before the universe" but we haven't really looked at how life began...

| Because I was absent nuclear power = Safe chernobyl = man made mistake alien life = evidence for it existing underground on mars 2 galaxys collide = the larger will devour the smaller (milky way is devouring a small galaxy as we speak) 2 galaxys of equal size (ie milky way and andromeda) will become a super massive galxy | 2010-07-16 08:28:00 Author: Kern Posts: 5078 |
| Does anyone think that people that says they saw/met aliens are telling the truth? Some stories seem very true imo :/ (Gotta go to bed soon) I always just assume that they are nutjobs, however I do definitely believe in Alien Life (I mean, it HAS to exist) but I maintain if they were advanced enough to reach us from a gargantuan distance and still be alive, they wouldn't be spotted by an American farmer on the fly (generalisation) unless they wanted to be spotted. However there are some unexplainable occurrences, like Roswell which I find quite intriguing. I was slightly convinced that the Norway Spiral was otherworldy but the explanation kinda makes sense. | 2010-07-16 08:47:00 Author: Boomy Posts: 3701 |
| Yeah boomys right, they wouldn't have developed interstellar travel to be spotted by a hick! | 2010-07-16 09:01:00 Author: Kern Posts: 5078 |
| Exactly, also, good morning. Even if that spiral was a failed launch, still looked absolutely fantastic. | 2010-07-16 09:05:00 Author: Boomy Posts: 3701 |

| Sorry for being absent guys. I fell asleep after working on my level and my house. I couldn't stay awake for "teh smart talk". But I'm here (I guess). Now, to bring back some light on the Mars matter. If we already stopped talking about it (or never talked bout it), then sorry, but I can't help but bring it up. There is life on Mars. They have found bacteria in Mar's polar ice caps, and even though the bacteria is dead, it proves that life is on Mars. Sadly, some scientist disagree that bacteria isn't a life organism at all, and that since they're dead they are not considered "life" on Mars. With that said, let's begin debating on the matter. Let the best team (Team "Yes", and Team "No) win! I call Team "Yes"! DEBATE! | 2010-07-16 12:06:00 Author: CyberSora Posts: 5551 |
| Of course bacteria is life, saying it is not is just ridiculous. I am team 'yes' if team yes is that there is life on mars. But technically, if it is dead there is no life at the moment, but there might be somewhere, it is a big planet. | 2010-07-16 12:10:00 Author: Boomy Posts: 3701 |
| Mars! Life? Yes!!?!?! Yes! | 2010-07-16 12:11:00 Author: Alec Posts: 3871 |
| But technically, if it is dead there is no life at the moment, but there might be somewhere, it is a big planet. Compared to the likes of Jupiter, it's a Little Big Planet. | 2010-07-16 12:15:00 Author: Rhys125  Posts: 841 |
| When I last looked at this thread two days ago it had about two pages... Now it has 21? This has got to be one of the fastest growing threads on LBPC. But anyway, I'm yes for the purposes of the debate. | 2010-07-16 12:16:00 Author: resistance1  Posts: 812 |
| Compared to the likes of Jupiter, It's a life wonderland. XD | 2010-07-16 12:17:00 Author: gdn001 Posts: 5891 |
| This is going to be a one sided debate.. BACTERIA IS LIFE! I AGREE! GOOD! | 2010-07-16 12:18:00 Author: Boomy Posts: 3701 |
| Guys, debate about it like there's no tomorrow. GIVE MEH REASONS!!! My reason. Because it's impossible for us to be the only living things in the universe. Surely Mars's conditions almost match ours. If they say that's our bacteria (possibly we contaminated the planet), then they just proved that we landed on the darn planet! | 2010-07-16 12:19:00 Author: CyberSora Posts: 5551 |
| Bacterias is life, how can you say they aren't? Bacterias need water to to live, doesn't they? And then there must be some kind of water on mars if they found bacterias! Or am I just dumb D: | 2010-07-16 12:22:00 Author: Alec Posts: 3871 |
| True, but they say that bacteria isn't the type of life they're looking for. Honestly, they were hoping to find "aliens", or so to speak. Oh, and reminder: THE DEBATE IS ABOUT WHETHER BACTERIA IS CONSIDERED AN ALIEN! So, is the bacteria in your eyes, or is it just a useless discovery and forever known as "just an organism"? | 2010-07-16 12:25:00 Author: CyberSora Posts: 5551 |
| When I mentioned evidence for life on mars I was referring to the oscillating methane levels that is only explainable through life,( Link (http://www.astronomynow.com/090116_IsMarsmethanethebreathoflife.html) Bacteria is life whether these "Scientists" remember that technically we started off as bacterium back when the earth was that writhing mass of boiling liquid. Whether the researchers have forgotten the first thing you learn in senior school (high school) the 7 processes of life (Movement, Reproduction, Sensitivity, Nutrition, Excretion, Respiration, Growth) and last time I checked bacteria fulfilled these criteria so these scientists aren't worth their salt, if they were looking for sentience which admittedly bacteria wouldn't qualify for then surely the easiest way would be to send a robot to enter the caverns of Mars.* Fin. | 2010-07-16 13:13:00 Author: Kern Posts: 5078 |
| Okay, fine, we all know they're life forms. The end. Now, can someone come up with a topic that'll make us actually DEBATE about it? | 2010-07-16 14:41:00 Author: CyberSora Posts: 5551 |

| Nuclear Energy although clean is almost as a bad as coal due to the mining required to harvest the uranium On the topic of the sea cities. There's a lot of different ways for the city to get energy, they could use the sun, the currents and the wind, the tides would also provide power the sea around them could be cultivated and crop land could be made available on the above sea levels the Walls would protect against storms and they could extract fresh water from the ocean and convert it into salt and fresh water, the rainwater could be used for more mundane tasks such as toilets and the crops, they could extract carbon dioxide from the atmosphere and change it into oxygen (for the lower levels) and carbon monoxide for construction of plastics etc... | 2010-07-16 16:12:00 Author: Kern Posts: 5078 |

| possibly but wormholes are the product of dead black holes. so theres a large chance we would never find one around our solar system. and just like black holes worm holes are singularities which are small as living hell so basically you would have to be the size of an atom to get through. and since space is so vast if you went through you could pop up any where so basically if you went through there would be a small chance you would be a pile of pink bubbles when you came out or you would be ripped apart into little pieces........or crushed by an intense amount of gravity or possibly eaten by something the size of a skyscraper, or put in some kind of advanced prison, or mabey even possibly killed by predator ee EDIT: you want a schmuck battle tough guy? what the schmuck are you waitin for? bring it on, may the best schmuck win | 2010-07-16 17:25:00 Author: Charlemagne Posts: 513 |

| Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. A few science fiction writers consider teleporters that preserve the original, and the plot gets complicated when the original and teleported versions of the same person meet; but the more common kind of teleporter destroys the original, functioning as a super transportation device, not as a perfect replicator of souls and bodies. Sounds like teleportation could be harmful to us hooman beings then!! But science fiction fans will be disappointed to learn that no one expects to be able to teleport people or other macroscopic objects in the foreseeable future, for a variety of engineering reasons, even though it would not violate any fundamental law to do so.

Awww... The main hurdle with teleportation technology isn't that it's physically impossible, it's that the actual technology to pull it off is so exponentially beyond what we have right now. There would be exabytes upon exabytes of data you'd need to store in order to perfectly break down, record and recreate or reassemble an object from an atomic level, let alone a human being. Even the slightest error would effectively ruin the process (not to mention what you were trying to teleport in the first place). | 2010-07-17 01:50:00 Author: Dapiek Absaroka  Posts: 512 |

| Small sub-subject, I'm currently watching one of my favourite programs 'Lie to me', those of you who are unfamiliar it is about an individual whom can tell if people are lying and what emotions they are showing by minute variations in facial expressions and body language, my query is, do you think this could indeed be such a reliable science, such as in this program?

| I never heard of it. But, I think I might have watched it once. Isn't it about a man who interrogates people, and for some odd reason he just knows they're lying. I remember watching something like this. | 2010-07-17 11:30:00 Author: CyberSora Posts: 5551 |

| Personally I believe in the Omniverse theory, if it all goes on for eternity outside our own universe then that's the only explanation for what could happen. At least when using human thinking anyway, I've got a theory that alot of fundamental facts we've got in our heads about the universe might not exist. For example, time, it may not exist according to some scientists and it's just how our species perceive the universe, like I saw someone mention it earlier in the thread nothing COULD exist it's just impossible for our minds to think that way. But for now I do believe in the Omniverse theory, here's a quick C and P from Wikipedia: "The Omniverse is the conceptual ensemble of all possible universes, with all possible laws of physics. Universe: The inside description of a context that is relative in size/structure (attributes/modes) to the known universe. Multiverse: The part of infinity that directly joins a given universe with all possible configurations of that universe. Omniverse: All possible attributes and modes are in play, multiverses are categorized by the attributes/modes active in its child universes. Some or all possible modes of existence are actualized." I like the omniverse theory because any world you can think of has to exist out there somewhere, it could be almost an exact same copy as this universe but you don't exist, or it could be completely crazy where white is black and black is white, it would make it possible for LittleBigPlanet to exist! Now that would be an awesome place to visit through our wormholes! | 2010-07-18 09:38:00 Author: olit123  Posts: 1341 |
| I agree. There just has to be other planets that support life or something like that. If you have an infinite space with infinite planets, infinite stars, and infinite galaxies, there is bound to be some form of life somewhere, anywhere, or possibly everywhere. There may be life in the vaccuum of space that we have no means of finding. No one actually knows... The "-verses" are a puzzling mystery that is far, far away from being solved. *Attempt at philosophy* :blush: | 2010-07-18 17:17:00 Author: piggabling Posts: 2979 |

| Regrowing Teeth Researchers are finding ways to use stem cells to regrow teeth--a potentially easier and healthier alternative to dentures and dental implants. By Jennifer Chu According to the U.S. Department of Health and Human Services, the average American will lose about eight teeth by the time he or she turns 50. Common replacements include dentures, which have been known to erode the underlying bone over time, and dental implants, which are prone to falling out after several years' use. Thus, the ability to regrow a natural tooth, with the accompanying bone, root, and nerves, could provide a significantly healthier alternative for many. Researchers at the Tokyo University of Science have successfully transplanted a bioengineered tooth into the mouth of an adult mouse. Credit: Takashi Tsuji Recently, a Japanese team from the Tokyo University of Science, led by associate professor Takashi Tsuji, reported in Nature Methods that it had successfully regrown a tooth from cells extracted from mouse embryos. The researchers were able to transplant the tooth into an adult mouse, and the tooth bud continued to grow to full size. Teeth in mice, much like those in humans, form during embryonic development from two major cell types: epithelial and mesenchymal. Epithelial cells give rise to the outer enamel, while mesenchymal cells form a tooth's inner connective tissue and blood vessels. Takashi's team isolated both kinds of cells from multiple mouse embryos, then transferred them to a collagen gel culture, in which the cells interacted to form a tooth bud. Researchers then transplanted the bud into the liver of an adult mouse, where the increased blood supply aided further tooth formation. Finally, Takashi inserted the tooth into an empty cavity within the mouse's mouth, in which it grew to full size. Whether the technique will be practical for regrowing teeth is uncertain. Paul Sharpe, head of the Craniofacial Development Department at King's College, in London, doubts that the technique will be useful for humans, particularly since the Tokyo team used embryonic cells, which are difficult to obtain in large numbers and may be rejected as a foreign substance when transplanted into a human adult. A better approach, Sharpe suggests, may be to use adult stem cells, which can be obtained from a patient's hair, skin, or other tissue; manipulated with the right molecular cues to form any kind of tissue; then transplanted back into the same person with less rejection problems.. Sharpe's lab is looking for adult stem cells, including those found in bone marrow and dental gum, as possible candidates for regrowing teeth. So far, he and his colleagues have had success with bone-marrow stem cells, forming teeth and transplanting them into mouse cavities. However, Sharpe says that obtaining such cells from human bone marrow is a painful process. In the next three years, he hopes to identify more-accessible stem cells that may be able to form not only teeth, but also--and more important--roots.

Scientists would still need to create a cure for cancer, whether it's in our lifetime or not!! It wouldn't just appear because you've time traveled!

And we've already established it would be impossible to travel back in time due to the possibilities of a paradox, so how would you bring the cure back? Simple. Go to the future, and get the cure. Then, go back in time to the first date you began the time travel. Example: I leave at 5:00 A.M., July 20, 2010 I arrive at the post-apocalyptic future at 6:00 A.M., July 20, 2010 *Gets cure.* I go back in time at 6:01 A.M., July 20, 2010 I arrive at the past/present at 5:01 A.M., July 20, 2010 So,no harm what-so-ever.

| If only we were Doctor Who's companion. Anyway, just a random question, to do with cryogenics, if you are flash frozen for lets say 1000 years, and unfrozen, would it be possible to be brought back? If you were un-flash frozen, so all your cells are defrosted at the same time. Or when you defrosted would you just be dead.. | 2010-07-19 17:27:00 Author: Boomy Posts: 3701 |
| I think you'll be dead. Isn't it like experiencing frostbite? You'll probably suffer internal bleeding, along with numbness and the loss of fingers after which you'll amputate, and that's if you live through all that ordeal. | 2010-07-19 18:24:00 Author: CyberSora Posts: 5551 |

| There have (according to QI) been reports of people freezing to death over night and coming alive again when thawed. A drunken Russian apparently did so. But I believe what actually happened was the cold slowed his metabolism considerably. It is the same reason a kid that got trapped under ice when he fell into a lake survived for over 20 minutes under water without drowning. kernelM is quite right the biggest problem with freezing is cell damage. | 2010-07-20 23:57:00 Author: Strangepom Posts: 445 |

Actually, they weren't dead. They were alive, but the intense cold slowed down their aging process, so they stayed the same. Basically, freezing a person will only slow down their cells, not stop it. Oh, and one more fun fact: a guy who snuck into an airplane by jumping on to the landing gear "froze" himself for hours, but "miraculously came back to life". Also, I think Kernel was talking about the ice crystal that form in the tissues. When you get a steak (for example), and put it in the freezer, small pieces of ice form between the tissues. This will lead to severe bleeding when it thaws out. Sp, if a person were to freeze themselves, they were to be dry and cold. That way, the freezing process would take less time and fewer ice crystals will form. | 2010-07-21 00:09:00 Author: CyberSora Posts: 5551 |
| ...if a person were to freeze themselves, they were to be dry and cold. That way, the freezing process would take less time and fewer ice crystals will form. Bu..but, aren't we like 60% water?

| Bu..but, aren't we like 60% water? Massive ice crystal damage, super effective! But if you do the same with meat, you'll see that it's not that effected. By dry I mean you have no water on your skin. That way, you don't get ice crystals in your pores. Your body fluids will not be frozen entirely, but instead slowed down. So your blood stream will have a very thin sheet of ice around the nerves' tubes. That way, it maintains a certain degree of cold temperature, while your blood steam is still active and flowing. Not to mention that if your blood were to freeze, the frozen blood would expand, causing your blood vessels to burst and/or rip, so freezing is probably a misunderstood term when it comes to this type of science. In fact, the scientist who do this type of experimenting probably laugh at people who misunderstand this process. This is all based on my theory of "freezing" people. I may be right, or I may be wrong. So sorry for going "scientific" on you. | 2010-07-21 02:44:00 Author: CyberSora Posts: 5551 |
| Haha no it's cool, I appreciate hearing your thoughts on it. Certainly they seem to make sense!

| how about we change science subject... what about cern and the theories around gravity being weak due to extra invisible bubble like dimensions, creation of black holes etc. Physics is much more my forte. Like Dayne said, elaborate on the subject. But until then, I want to jump back to an old topic. You know how we said that time traveling will cause a paradox? Well, I thought about the matter very hard, and here's what I came up with: Theory A: What if everything that has ever happened included time traveling? Think about it. Maybe Bush did get killed in the terrorist attacks, but someone in the future went back in time to stop it, but miserably failed and instead crashed the airplanes, hence 911. Theory B: Maybe everything is suppose to happen under whatever circumstance, no matter what. So let's say that after LBP2 was announced, an XBox360 fan said "You know what, I'm going to get Mm to make LBP2 for XBox360. Why? Because we're awesome and way better than PS3!" So, the guy goes back in time just minutes before the announcement and meets the Mm team. Well, he goes on about the XBox360, and how better off they'll be if they switch sides. Finally, Tom tells him "Look kid. We we're going to release it for XBox360, but after hearing you, we realize that XBox360 is full of annoying people like you. So, we'll stick to the PS3." So, it was actually the kid's fault for making LBP2 a PS3 exclusive in the first place. Theory C: We have gone back in time, but then everything just resets when we leave and/or we want it to reset. You know, like if I shoot a guy now but decide to leave the time and reset everything whether I want to or not. So, I'll be gone and back in my time, while the guy is alive again and has no memory of what just happened, and no time has passed at all. Reset. Theory D: No one has time traveled. Ever. If we did, then why don't we have time travelers around here? If we did time travel, we would've see them by now... unless they're invisible and have a rule of no interaction with the past/future. That's all I got right now. Debunk/approve of my theories if you like. Peace | 2010-07-21 17:35:00 Author: CyberSora Posts: 5551 |

Maybe Bush did get killed in the terrorist attacks, but someone in the future went back in time to stop it, but miserably failed and instead crashed the airplanes, hence 911. That would fall under the parallel universe theory thing, where everything that can happen, has happened. Personally I don't believe that theory, but oh well! Theory B: Maybe everything is suppose to happen under whatever circumstance, no matter what. So let's say that after LBP2 was announced, an XBox360 fan said "You know what, I'm going to get Mm to make LBP2 for XBox360. Why? Because we're awesome and way better than PS3!"

So, it was actually the kid's fault for making LBP2 a PS3 exclusive in the first place. Despite being a little crude, I also believe this, that time repairs itself no matter what, or even if you change something in the past, you cannot go back to the future, and you end up in another dimension / parallel universe. (See film "D?j? vu" where time travel theory is that a new timeline created when you change the past, runs parallel to the old unchanged one) Theory C: We have gone back in time, but then everything just resets when we leave and/or we want it to reset. You know, like if I shoot a guy now but decide to leave the time and reset everything whether I want to or not. So, I'll be gone and back in my time, while the guy is alive again and has no memory of what just happened, and no time has passed at all. Reset. Like I said a little earlier, I don't believe we would be able to go back... Theory D: No one has time traveled. Ever. If we did, then why don't we have time travelers around here? If we did time travel, we would've see them by now... unless they're invisible and have a rule of no interaction with the past/future. No, I don't believe anybody has time traveled from our time. I heard another theory that says UFO sightings could possibly be human beings travelling back from the future. I have a cool topic. If the sun had a polar shift and it sent these emp's to earth, would all electricity go out? and will we all go back to the dark ages? Probably not possible due to the magnetosphere (http://en.wikipedia.org/wiki/Earth%27s_magnetic_field) created by the earth's core. I think it would stop the EMP before it even entered out atmosphere. | 2010-07-21 20:14:00 Author: Weretigr Posts: 2105 |
| I like this discussion, "trousers of time" and "the whole general mish-mash theories" (to quote Terry Pratchett and Douglas Adams) There is a theory that states time travel with the future would not be possible until a devise has been created to be the other end of the conduit. Which is why we don't see future time travelers walking around now. Also the changing future theory (your LBP xbox example) can be explained with the multiple 'probability' dimensions. Yes it did happen and changes can be made but not in the continuum that the annoying xbox fan came from. So that is kinda agreeing with DaneOrams view.

| Feck the sun having a polar shift, what if Earth had one? Which technically we are over due one if history is to be followed. Not to mention a weakening magnetic field that loses strength every decade. From what I've heard the magnetic field almost completely deteriorates, the the poles flip. This would allow radiation to get in all over the planet, I don't think it has been linked to any mass extinctions so I dunno what kind of risks there would be for us, we'd all need to pack on sunblock 1000 that's for sure!

| i thought that the polar shifts were internal and we'd not feel massive effects but then again im not quite sure of any facts on this topic so /runs We would feel massive effects. If Earth's poles were to shift (which they will, by the way), they'll create earthquakes around the world, and we'll have a messed up magnetic field that we'll have to get used to/re-coordinate with again (mainly electronic items that use radio signals, WiFi, etc.). | 2010-07-22 14:59:00 Author: CyberSora Posts: 5551 |
| Humans themselves wouldn't feel massive effects inside our own bodies, as long as radiation wasn't involved. From what I understand, the poles would switch extremely quickly, so radiation wouldn't be that much of a problem I would assume... I'm not sure though. Back to the effects, are you certain that earthquakes would occur? I'm under the impression that the poles of the of the rocks would just switch due to the reallignment of magneticized perticles and whatnot. Although, I'm not saying they wouldn't move for certain. There's no doubt something would shift, but I can't imagine it being to that extent. If our electronics weren't already whacked out, then the field changes of rocks would surely interfere with them. | 2010-07-22 15:54:00 Author: piggabling Posts: 2979 |
| Humans themselves wouldn't feel massive effects inside our own bodies, as long as radiation wasn't involved. From what I understand, the poles would switch extremely quickly Extremely quickly = a few thousand years. lol Well I am sure the actual shift can happen in a matter of years but the degradation of the magnetic field would take a few thousand years and that would leave us with lowered defenses for several generations. | 2010-07-22 18:30:00 Author: OneEyedBanshee Posts: 1370 |

It concerns a cat that is sealed inside a box for one hour along with a radioactive element and a vial of deadly poison. There is a 50/50 chance that the radioactive element will decay over the course of the hour. If it does, then a hammer connected to a Geiger counter will trigger, break the vial, release the poison, and kill the cat. Since there is an equal chance that this will or will not happen, Schr?dinger argued that before the box is opened the cat is simultaneously both alive and dead. In short, the point of the experiment is that because there is no one around to witness what had occurred, the cat existed in all of its possible states (in this case either alive or dead) simultaneously. This notion is similar to the old ?if a tree falls in the woods and there?s no one there to hear it, does it make a sound?? riddle. Schr?dinger originally conceived of his theoretical cat in response to an article that discussed the nature of quantum superpositions, a theory that defines all the possible states in which an object can exist. Schr?dinger?s Cat also helped to illustrate just how weird the rules of quantum mechanics really were. The thought experiment is notorious for its complexity, which has encouraged a wide variety of interpretations. One of the most bizarre is the ?many worlds? hypothesis, which states that the cat is both alive and dead, and that both cats exist in different universes that will never overlap with one another. | 2010-07-23 00:28:00 Author: Weretigr Posts: 2105 |
| And the final theory I'm posting for now is the "Brain in a Vat" theory; There has been no more influential thought experiment than the so-called ?brain in a vat? hypothesis, which has permeated everything from cognitive science and philosophy to popular culture. The experiment asks you to imagine a mad scientist has taken your brain from your body and placed it in a vat of some kind of life sustaining fluid. Electrodes have been connected to your brain, and these are connected to a computer that generates images and sensations. Since all your information about the world is filtered through the brain, this computer would have the ability to simulate your everyday experience. If this were indeed possible, how could you ever truly prove that the world around you was real, and not just a simulation generated by a computer? If you?re thinking this all sounds a bit like The Matrix, you?re right. That film, along with several other sci-fi stories and movies, was heavily influenced by the brain in a vat thought experiment. At its heart, the exercise asks you to question the nature of experience, and to consider what it really means to be human. The idea for the experiment, which was popularized by Hilary Putnam, dates all the way back to the 17th century philosopher Rene Descartes. In his Meditations on the First Philosophy, Descartes questioned whether he could ever truly prove that all his sensations were really his own, and not just an illusion caused by an ?evil daemon.? Descartes accounted for this problem with his classic maxim ?cogito ergo sum? (?I think therefore I am?). Unfortunately, the brain in a vat experiment complicates this argument, too, since a brain connected to electrodes could still think. The brain in a vat experiment has been widely discussed among philosophers, and many objections have been raised over its premise, but there is still no good rebuttal to its central question: how do you ever truly know what is real? This is something I have thought about quite a few times... I think we should discuss these two theories, perhaps not both at once (We don't want to over-work our brains now, do we?!) but both of them eventually. | 2010-07-23 00:32:00 Author: Weretigr Posts: 2105 |
| Sorry for the triple post, but I'm separating them because they are completely separate theories / articles! Back to our time travel / paradox discussion: Scientists have for some years been able to 'teleport' quantum states from one place to another. Now Seth Lloyd and his MIT team say that, using the same principles and a further strange quantum effect known as 'postselection', it should be possible to do the same backwards in time. Lloyd told the Technology Review: "It is possible for particles (and, in principle, people) to tunnel from the future to the past." Postselection is a vital part of the nascent science of quantum computing. In traditional computing, if a user needs to determine which set of variables in an equation leads to the answer being true, the computer must try every combination until it hits upon one that works. In quantum computing, due to the weird parallel behaviour of subatomic particles, it seems to be possible to simplify the procedure by running all possible variations simultaneously, and selecting only the combinations that make the answer true. Related Articles Ben Bernanke: the man determined not to preside over a second Great Depression World Wide Web creator Sir Tim Berners-Lee fell victim to online fraud Hyundai backs car which uses sunlight Why Whitehall hates solar panels GM could have a future in the greening of Detroit Nasa 'elated' after new telescope uncovers 'previously invisible space objects' Professor Lloyd and his team say that, by combining teleportation and postselection, it would be possible to carry out the quantum teleportation effect in reverse; that is, to decide after the teleportation what the quantum state must have been before it. This works as postselection allows you to dictate which quantum states can be teleported, limiting what state it can have been in before the teleportation. The state of the particle post-teleportation has therefore, in effect, travelled back in time. Dr Richard Low, a quantum computing scientist from the University of Bristol, says: "You could think of it as postselection affecting the history of the particle, sending the state back in time." Unlike previous theories of teleportation, this apparently avoids the "grandfather paradox" - or, to Back to the Future fans, the Marty McFly problem. If you go back and change time, and accidentally end up killing your own grandparent, you create a paradox - you will not be born, so you cannot go back and affect time. Even with subatomic particles, this is still a problem: upon travelling back in time, the particle could somehow destroy its earlier self or move it, thus preventing it from travelling. However, because of the probabilistic nature of quantum mechanics, Prof Lloyd's method seems to avoid this. Anything caused by the time travel must have had a finite probability of happening anyway, so paradoxical impossibilities are out. Further, this time travel method does not involve bending spacetime, unlike other proposed systems. At the moment, the only conditions known that would bend spacetime sufficiently exist in black holes, which would be impractical at best. It is a controversial theory, to say the least. Some physicists claim that the apparently impossible things implied by postselection prove that it cannot work, which would destroy Prof Lloyd's theory before it got off the ground. The theory is unlikely to lead to DeLorean time machines or anything remotely similar. Instead, Prof Lloyd and his team hope that it can advance our understanding of physics: "Our hope is that this theory may prove useful in formulating a quantum theory of gravity," he says. Link.

| Only read 2 pages so, sorry if this was posted before. Thought you might find this interesting Everything is energy. The closer you look at atoms, the more space you'll see. 'Matter' is 99.9% space, .1% matter. The particles that ARE matter stll get divided up until the only thing left is compressed energy. The space inbetween the energy particles? Occupied by energy. Energy is created from space, so energy and space/time are part of one whole. 'Empty Space' is not so empty, the act of having 'space' gives way to the possibility of energy which is the building block of matter. We normally consider reality to be energy and matter, but since space is part of the same whole as energy, it is part of reality. With the existance of any reality comes the potential for any of the other forms. Reality is your perception of the energy and space around you. If you alter your state of mind and will your own reality, you will ultimately distort and change how you perceive what is in, and makes up, your reality. Nothing is real. Nothing does not exist. Nothing exists outside of your mind. Everything you experience is formed inside your mind from your brain processing energy frequencies and turning them into sight, sound, hearing, etc. | 2010-07-26 06:14:00 Author: Bremnen Posts: 1800 |
| OH MY GOSH!! MY FAVORITE SUBJECT!!!! Actually that paradox about the cat being alive and dead at the same time is called the Measurement Problem. I really don't like guess work : and that's why I don't like quantum physics. It's all about the "probability" that something will happen, but you don't know that something will happen for sure. And that paradox of the tree falling down in a forest. Does the tree make a sound? I really don't understand it : of course it will make a sound. It's a tree just because your not there doesn't mean it didn't make a sound. If someone is crying across the world does heshe make a sound? YES!!!! Someone explain to me the tree paradox : | 2010-07-26 06:58:00 Author: Amigps  Posts: 564 |

| that would be strange if this was a universe based off someones own mind, if that one person knows how to do it right, and if this reality is close enough to a dream then they could bend the fabric of time and space into their own chosen world and we would be puppets and he/she to be the puppetmaster. who this person is we might never know. if this universe is an illusion, then all of you are very detailed illusions if not, then my heads not going to explode. i have another theory and this one i thought of a long time ago. i had a dream, in it was my friends, my family, my enemies. it just was a regular day, all of a sudden i discovered something not quite right a person was having a cup of coffee with another person despite the fact that they had absolutely no way of knowing each other, no connections, no people knowing people that just happen to meet people, just a very coincidental conversation, had i saw them outside the wall of my house that just happened to be a stage room i probably wouldnt have believed that there was something creepy about that dream, then they explained to me how everything was just a setup, how everyone i knew was an actor and it all lead up to me as if i was some kind of god. it was freaky. really freaky | 2010-07-26 16:32:00 Author: Charlemagne Posts: 513 |
| Yea, i think you would really have to mess with your pysche but it sounds possible. By mess i mean, completely detach your mind from your brain. Which would basically be, having a total psychological breakdown but still be in controll, if that makes sense. That way, how your mind and brain react and function would be scattered enough for you to go in and force your mind to make your own reality. This creates an interesting dilema, since you've created your own reality, what happens to you in everyone elses reality? Assuming that we're not all just part of one persons dream/mind/whatever, would they view you as crazy? Would your body die? Since you have a reality that you made, would you still exist in everyone elses? Dreams are formed by your brain taking memories,thoughts, bits of your imagination and peicing them together. Everything you've ever heard,seen, experienced,thought, things you dont even remember that happened, are up for grabs when you have a dream. Literally, the tree would not make a sound. It would create an energy wave on the frequency that we register as sound, but if noone is around then that frequency doesn't get processed into sound. The five senses don't exist outside of your mind. Metaphorically, yes. Even though its not processed into a sound, the energy wave and the potential for that wave to be processed into sound is there. | 2010-07-27 08:54:00 Author: Bremnen Posts: 1800 |

| Lol what he said We are complete automatons who can only react to stimuli and are fueled by the energy particles and waves of the universe. The mind is like a computer, it knows as much as was put into it. The mind is made of complex energy frequencies built up of simple frequencies and reacts to stimuli put into it. An energy wave contains all of the frequencies that i breaks up into and combines to form energy molecules 'atoms'. Atoms and energy are two forms of the same substance. From that its not too far off to consider empty space, energy, and atoms, all the same substance since the latter two originate fom the first. An example is a mirror, you can see objects and light reflect off of it but its still the same mirror. Since the mind is made up of these waves, we have the ablity to know everything our anscestors knew, saw,thought,heard,etc. These things are locked away in our minds, passed on by DNA and energy frequencies. If you were to break away from the constraints of your physical body and brain, you would get a chance to experience some or all of these things. Though the strain on your mind would lead to a sensory overload in most cases, and portions would be lost. In essence, you would learn things but not be able to remember how. Or forget some of the things you experienced. | 2010-07-27 11:13:00 Author: Bremnen Posts: 1800 |

| No, completely different personalities with completely different thoughts that you don't remember you had or how you acted. its part of a defense case for a schizophrenic guy who committed a crime but couldnt remember what happened and knew it as wrong when questioned. "One mind can have multiple personalities. You can be tried for your bodies actions even when it was another personality and you have no recolection of what transpired. This is unjust, one should not be punished for what took place when he was unconsciously irrational. You should only be punished if you know what you did, were conscious, and chose to do it knowing it was illegal or wrong." | 2010-07-28 02:33:00 Author: Bremnen Posts: 1800 |

| I RESURRECT THEE! :kz: So, as we all know the greatest Geek Bible to be ever written (The Hitchhiker's Guide To The Galaxy) proclaims that "the answer to life, the universe and everything is 42". Well, I beg to differ! I see this to be an excuse I say, an excuse! That computer is hiding something, and I think we should discuss on something it has mentioned to the Hitchhikers as impossible to answer in the same universe: what is the ultimate question? So, what is the ultimate question? DISCUSS! :kz: | 2010-08-01 01:47:00 Author: CyberSora Posts: 5551 |
| The ultimate question would have to be: Are we even real? That question is more important that knowing how the universe began ot why we are here. If we're just part of a dream, or an illusion, whats the point in all the other questions? | 2010-08-01 01:55:00 Author: Bremnen Posts: 1800 |

| But then thats just a question asking for a quesion, not an answer Exactly! A question that answers a questions is both mystical and never ending! It's the ultimate question because it has no answer! | 2010-08-01 02:03:00 Author: CyberSora Posts: 5551 |
| That just makes it a paradox! The ultimate question has to have a direct answer or theres no point in it being the ultimate question since your trying to find an answer,not go in circles! | 2010-08-01 02:10:00 Author: Bremnen Posts: 1800 |
| But why!? If the ultimate question's answer is direct, then it won't be true. For example: What's the ultimate question? Answer: The answer is "What's the meaning of life?" Technically you're asking for a question to be an answer. So the answer is a paradox. Not only that, but in my perspective the ultimate question is "What is the ultimate question?", because it is the greatest mystery ever. | 2010-08-01 04:01:00 Author: CyberSora Posts: 5551 |

| The big bounce pretty much sums it up for me. What really hurts my brain is the grandfather paradox of time travel. If you travel back in time to kill the anscestors of someone that's tormented you your whole life, when you kill them the tormenter dies but then the motive dies too which causes the bully to be both alive and dead at the same time...

| Temporal Paradoxes. There's plenty of speculation about it; Einstein theorized that even if you could travel back in time, you wouldn't be able to change history but rather whatever you did to try to do so would only assist in making history taking the course it already had and create a stable time loop. Lets say, if you in fact did go back in time to kill some ancestors of someone who tormented you (not exactly justifiable at all, mind you), you might very well fail and their near-death experience would leave a lasting impression that would influence how they raised their descendant and turning that person into the tormentor you hated, thus making you responsible for your own misery. Another possibility is that if you could travel back in time and change history it wouldn't affect your present, but rather that your actions ended up creating a divergent, alternate universe where the changes you made were played out. Those who actually do believe in the possibility of alternate universes also theorize that you don't even need something like time travel to create an alternate universe, but rather any choice anyone and anything makes causes the creation of alternate universes where different outcomes of those choices play out, resulting in a near infinite number of universes created by the several possible combinations of outcomes of events, but that's sort of getting into quantum mechanics there... | 2010-08-01 17:47:00 Author: Dapiek Absaroka Posts: 512 |

| Time Travel would only be as a Viewing, not a Alteration. If you went back in time to stop someone you knew being Killed, then present (By which I mean the you that lives in the future where you have saved said person, yet would b unawre of it being you, since it wasn't you, but rather another you) you would not have the reason to go back in time, as said person not being dead would mean you've not to save them, meaning since you didn't go back - you wouldn't of saved them! But then if they're dead, you (back being the current you, back in the Timeline of that person being dead) would go back in time to save them - All equaling to Two Timelines crossing over continuously, which would look alitle something like This? (http://www.csb.yale.edu/userguides/graphics/ribbons/help/dna_rgb.gif) Interesting, no? As for the Viewing part, You could only go back in order to see the events, to gain knowledge for Future (Present) you - Ie: Who? Killed said person? But if you were there, Watching them die, could you help yourself in not trying to Prevent it? | 2010-08-02 00:18:00 Author: Nurolight Posts: 918 |

| A quote from h2g2 * ?The Encyclopedia Galactica has much to say on the theory and practice of time travel, most of which is incomprehensible to anyone who hasn?t spent at least four lifetimes studying advanced hypermathematics, and since it was impossible to do this before time travel was invented, there is a certain amount of confusion as to how the idea was arrived at in the first place.* One rationalization of this problem states that time travel was, by its very nature, discovered simultaneously at all periods of history, but this is clearly bunk.* The trouble is that a lot of history is now quite clearly bunk as well.? | 2010-08-02 09:31:00 Author: Strangepom Posts: 445 |
| What if you just went back to mess with everything you saw, you didn't go with a specific purpose just general mayhem, therefore the motive wouldn't change? But then how would you know you havent just seriously changed things? Say you went to Califonia in 1974, & Randomly shot up a building? Alls fair right? Now lets say one person you just happened to shoot was a Mr Jobs? You've just randomly stopped your Future (Present) self from getting an iPod?! Ok, not a big deal...But! Think of how many things you've change just because of that? A Very popular Portable MP3 Player suddenly doesn't exist, meaning barely anyone now walks around with earphones in - meaning, you've probably just saved alot of people from being Killed in Road Accidents!
