http://www.telegraph.co.uk/science/8782895/CERN-scientists-break-the-speed-of-light.html


Puzzling results from Cern, home of the LHC, have confounded physicists - because it appears subatomic particles have exceeded the speed of light.

Neutrinos sent through the ground from Cern toward the Gran Sasso laboratory 732km away seemed to show up a tiny fraction of a second early.

The result - which threatens to upend a century of physics - will be put online for scrutiny by other scientists.

In the meantime, the group says it is being very cautious about its claims.		2011-09-22 20:50:00

So the speed of light would no longer be the speed limit of the universe?

DUN DUN DUN O FRAK. Maybe it IS feasible to travel faster then light? Or at least physically possible?

Like zomg. Here I was thinking the speed of light was the universal speed limit, but nooooooooooo, the universe has to be all "HAHA SCREW YOU STUPID HUMANS" and make itself even more complex. Well, guess what universe? We're now going to find out how to do FTL. And when we send our armadas against you and you're infinity... Oh, you'll regret messing with us. You'll see :kz:		2011-09-22 20:57:00

This sounds... like it could get big.

Too tired and sick to care right now though.		2011-09-22 21:03:00

Oh Rock, Y U SO MAD?

I actually love this news! Think about it: we always thought light speed was the fastest speed in the universe. But if we actually find faster-than-light speeds, then who knows what technology we'll be creating in the future. This is probably a step closer into reaching the ability to use wormholes or something of the like. 		2011-09-22 22:28:00

Huh? who said I was mad. I think it would be cool if some of that sci-fi stuff was possible. I just thought that it was something that actually WAS impossible. Like time travel. But if the speed limit of the universe isn't a constant... then maybe time is more abstract then we thought, and it is possible to rewrite the fabric of existence so that peanuts were the dominate food throughout the ancient world in lieu of wheat, rice and maize despite not having any of their positive qualities enabling the mass producible way of developing a civilization... Or maybe alternate realities do exist, including one where I am NOT an evil warlord with a bizarre peanut fetish. Pfft, like I'd ever be some geek on a computer or anything.

This is just another example of the universe trying to make our heads implode with the pure impossibility of its own existence. If the universe keeps trying to make us question if it even exists... Well, if there's one thing mankind has shown an aptitude for, it's war... So we can probably declare war on the universe. right? Declare war on everything? On existence itself? Unless, of course, this leads to the argument that existence, in itself, is more then we think it is, so the universe could not even be all of existence... but, seeing as how humanity just uses the world "universe" as an abstract concept to include everything imaginable, well, how could existence one up us there? How can our own world for "Everything" not MEAN everything?

Well,a s you can plainly see, we know nothing ABOUT existence. Pretty much every theory we've ever had has been about the universe has been disproven. So, how can anything we discover BE the truth?

Is there even a truth? In a universe that rewrites itself to screw with humanity, how can we be sure there even IS such a thing as reality? How can anything truly exist?

Well, the mere fact that I am able to comprehend some limited scope of the universe proves SOMETHING is there. Words only explain our interpretation of things. Thus, nothing can not exist, because something DOES exist. Even if it isn't "Reality" or at least our perception of reality, even if we are a dream, something HAS to exist.

So, going back to the whole light speed thing, if the universe can rewrite itself so that any attempt at understanding it is disproven fairly quickly... is there even an answer? IS REALITY TRYING TO SCREW WITH US?

Or am I posting a bunch of random BS that has nothing to do with the topic at hand due to my own boredom?

So, to answer your question... I am not "mad". I just didn't want to say "THAT'S COOL YO", an somehow I devolved into random tangents. Like I did just now. ;o		2011-09-23 00:54:00

http://webcast.cern.ch/ 2011.09.23 16:00 CEST - New results from OPERA on neutrino properties

Set to start around 3 hours from now at time of posting. Not sure if it'll be presented in English or not, though.		2011-09-23 11:54:00

Scientists really are working fast these days, making stellar enlightening discoveries like these possible.

Those opposed to science could use this discovery to say what else may be wrong? They should lighten up.		2011-09-23 12:46:00

Seminar at above link has just started. Appears to be in English.

Edit: Over now.

Nobody could pick holes in the presentation during the Q&A session and got kind of silly when someone suggested the title of the presentation was wrong.

Apparently there is an ongoing experiment of the same kind in America that was briefly mentioned, so I guess whenever that's finished that would be where we could first expect verification of these measurements if they turn out to be correct.		2011-09-23 15:00:00

Neutrinos have always traveled faster than the speed of light. However nothing can accelerate to the speed of light, because it's mass would be infinite. Also the results have yet to be verified independently of CERN.

EDIT: Something I forgot to mention, neutrinos may have no mass. If this is true, then they can accelerate to the speed of light as anything multiplied by zero will equal to zero.		2011-09-23 17:44:00

Why didn't they build a small hadron collider first to see if it worked?

That is a very amazing find, but that doesnt really change anything. Solid matter would still probably disintegrate going at that speed. Depends, what kind of particles were they? regular atoms or compunds?
Edit: Nevermind, just saw the subatomic particles part, but yeah, still pretty cool, so is it just subatomic particles and energy, or does it affect all 4 states of matter?
Another Edit: Just read the article, they think that time travel could be possible, which is absurd, there is no such thing as time. Time is a human invention and a human idea. Time occurs as a straight line, hence the word timeline. The only way you would be able to go back in time, is if you were able to go forward in time. And even then, that would only be if the universe reset itself in some way, and thats if you were totally intact and alive somehow if the universe ends and begins again, which is highly unlikely, there is a lot of factors that occur when you talk about time travel, however, i dont think its possible to go back by other means than going forward, and if you saw yourself in the past, then your past self would see you from the future, etc. I just dont think thats the case.		2011-09-24 00:36:00

I was always skeptical about that. I figured if anything was given enough inertia, it could easily go faster than the speed of light.

Especially since neutrinos are considered elementary particles and don't have any "known" sub parts.

So they can't break down or disintegrate.

Either way, this doesn't make Einstein's theory of relativity completely wrong (obviously). May just need some recalculations, just as Newtons laws of gravitation were redefined by Einstein.

Plus, my cousin's dad is a physicist. New discoveries keep him his job. ^^		2011-09-24 03:28:00

If anything was to go at the speed of light or faster it would be neutrinos. They can go through almost anything like "a bullet through fog". This means there wouldn't be much friction against it to slow it down.2011-09-24 05:27:00

Time occurs as a straight line
Or does it? My head is aging faster than my feet (or the reverse if I'm doing a handstand ), unless that's not what you meant by a straight line.


i dont think its possible to go back by other means than going forward.
I haven't really looked into but there's a theory that if you were to go back in time you wouldn't just be going back in time but also to a parallel universe thus avoiding any paradoxes.

Anyway, going faster than the speed of light eh? Sounds interesting, I'm not quite believing it yet (though someone was saying it's only particles that have no mass?) I'll have to give those articles a read some time.		2011-09-24 06:04:00

I've got a theory (based on no evidence other than a hunch) - that the reason that hours in the morning seem to go faster than in the evening is due to the doppler effect (http://en.wikipedia.org/wiki/Doppler_effect) on space-time. So in the morning we're heading "upstream" (faster time) and in the evening heading "downstream" (slower time) - caused by the earths rotation.
Obviously this affect would be miniscule - but may be barely perceptible by humans.

Of course, the other theory is that we are already travelling backwards through time - that's why we can see the past 		2011-09-24 06:52:00

CERN's trying to test that theory. People have pointed out neautrions several times a long time ago, but this is the first time it makes big news because it's actually being tested now.

Yeah, and didn't he sing;
"That's why they call me Mr. Fahrenheit, I'm travelling at the speed of light;
I'm gonna make a supersonic man out of you!"

That's travelling "at" the speed of light - not faster than the speed of light

Get your physics right Fredd... err Nikola 		2011-09-25 02:48:00

The neutrinos do not travel with superluminal velocity all the way. They only ?jump? a small initial distance shorter than 20 meters, after which they settle back and travel as usual with speeds below that of the speed of light. This initial jump would occur at speeds that are more than ten times the speed of light, perhaps even millions of times the speed of light.
