The Paradox Thread

Archive: 63 posts


Hey guys, i was recently thinking and i thought that maybe we could discuss Paradoxes.

A Paradox is a statement or proposition that seems self-contradictory or absurd but in reality expresses a possible truth.

ill start with one

The below statement is true
The above statement is false

What would happen if you had two portals (Like in the game, but forget its mechanics for now), one placed on a wall and another on a sheet of wood - then you put the sheet of wood with portal and everything into the one on the wall?2011-04-23 01:55:00

That, I believe would be the equivalent of dividing by zero. Best case scenario is that the board placed through the portal will create more of itself, eventually disappearing into itself once it exits itself. Worst case scenario, the portal becomes self-containing and promptly devours the universe in constantly fluctuating black hole type of portal.

If the portals were the same size it wouldn't fit. It would just go out itself if it could, shrinking forever. No paradoxes. I WON.

And time travel. You go back in time to stop something and succeed, therefore you don't have to go back in time in the first place to stop it. Since you didn't do it, the thing happens, making you need to go back in time to stop it. It doesn't happen, so you have no reason to go back in time. Since you didn't do it, the thing happens, making you need to go back in time to stop it. It doesn't happen, so you have no reason to go back in time.

i have thought about this way too much.
his nose will stay the same size during the period described as 'now' when the statement has not become a lie yet.
once the 'now' period is over then his nose will grow because that statement has become a lie and his nose growing then will not alter the validity of the statement. so his nose will wait a moment before growing

either that or he will explode

They'll cancel each other out.

Portal A will disintegrate in Portal B, more than likely doing nothing.

But then there's the black hole theory in which both portal become compact and merge into one portal, one coming out of the other in rapid succession that it'll give off the black hole effect, if not actually become said hole.

But who am I with my silly theories? Let's just say magic happens.

Theres a simple solution to the "immovable object + unstoppable force" thing. The unstoppable force collides with the immovable object. THe unstoppable force then BOUNCES OFF, but does not stop. I win.2011-04-23 21:42:00

Actually nature "hates" paradoxes because of balance issues.
I think that 2 portals near to each other act like the poles of magnets, repelling themselves.

A mad scientist opens a wormhole 1 second into the past - and shoots himself through it (he 'is' mad after all).

This means he is not alive 1 second in the future in order to open the wormhole to the past in order to shoot himself, so he would still be alive and therefore would be able to open the wormhole and shoot himself, which would mean he would not be alive 1 second in the future.... (repeat ad infinitum)

4. If the universe is infinite, have we accurately measured it? (Not really a paradox)
5. A passion for hating
6. life after death

1. A Universe coming from nothing
2. If any and everything exist, can "nothing" exist?
Nothing is a term made by humans, not an existance, so depends pretty much on the definition and on who you're asking.
I could call the implosion that allegedly started the universe "nothing" and thus meaning the universe DID originate from "nothing" and that "nothing" exists or existed.

3. God (lol sorry)
?

4. If the universe is infinite, have we accurately measured it? (Not really a paradox)
That's not a paradox, that's just a question...

5. A passion for hating
Not paradox, loving to hate is not paradoxical at all, since you like the emotion "to hate stuff" you like the emotion, but you still dislike the stuff you hate.
Now Loving what you hate would be something closer.

6. life after death
...not a paradox, a belief, life DURING death would be closer, but who's to say death isn't just another step on life?
Again, life and death are human terms that can be manipulated in different ways.

7. living your life
That's not a paradox, that's being redundant...

8. blackholes
Would you explain why or how?

9. traveling back in time to a point where you are traveling back in time
Travel back in time paradoxes don't really exist, as time travelling in itself does not have solid rules set to itself and can be shifted accordingly to what people want to imagine them them to be.

For example, the theory of alternate universes kills all "If you back in time and kill yourself it means you don't back in thime and all that" paradox, what would happen would beyou kill yourself and die in that specific universe, thus creating an universe with you dead, and when you return to your time, either nothing will have changed, or you would've gone into the future of that specific dimension only, but no real "paradox."

10. eating your own head
Not really, as even if one could eat their own head, you would consume it until you reached a "lethal point" of consumption where there' no way to eat more without being lethal, thus stopping the self-head eating process.

11. imitating yourself
Nope, you can always imitate how you acted some time before, which is not paradoxical at all.

Can't think of any more lol
That's because you didn't think of any!

LOL thanks for calling me out...on everything...

I guess I'll return the favor...

"Nothing is a term made by humans, not an existance, so depends pretty much on the definition and on who you're asking.
I could call the implosion that allegedly started the universe "nothing" and thus meaning the universe DID originate from "nothing" and that "nothing" exists or existed."

By definition, nothing is the absense of existence.

So the paradox is that if EVERYTHING and ANYTHING exist, can NOTHING exist? Can the absense of existence exist if EVERYTHING exist basically. Hop the caps are helping you understand...

When I said God I meant the whole concept of an omnipotent. omniscience, omnipresent being existing (based on religious views at least)

That's not a paradox, that's just a question...

Yeah i know...that's why I put in parenthesis "not really a paradox" Was just something interesting I thought of...

I said blackholes because to me, the idea of something becoming so massive that gravity wipes it out of existence...well im not sure about that one...it sounded like a paradox in my head lol

Travel back in time paradoxes don't really exist, as time travelling in itself does not have solid rules set to itself and can be shifted accordingly to what people want to imagine them them to be.

Do any paradoxes exist?

Not paradox, loving to hate is not paradoxical at all, since you like the emotion "to hate stuff" you like the emotion, but you still dislike the stuff you hate.
Now Loving what you hate would be something closer.

Well yes, but what I meant was that if you love to hate then how can you hate if you love it?

How can you love the "feeling of hate"?

It's like saying I'm happy because I'm sad.

not a paradox, a belief, life DURING death would be closer, but who's to say death isn't just another step on life?
Again, life and death are human terms that can be manipulated in different ways.

All your arguments are semantic.

I think i probably should've said "life in death". Sorry

That's not a paradox, that's being redundant...

Touche, but i was thinking that if you're alive then you're living your life. So when someone says "live your life" it sounds like there are saying someone who is alive is dead.

I think i was thinking of saying "the living dead".

Nope, you can always imitate how you acted some time before, which is not paradoxical at all.

Well, I didn't mention that the act of imitation was based on a temporal self.

The paradox is that if you are yourself, then how can you act like yourself when you are ALWAYS acing like yourself because you are yourself?

That's because you didn't think of any!

I guess the first one isn't a paradox?

Eh, fair enough, see, we both have different points and view of this, which is kinda my point as well, while it may be a paradox to you, it is not for me, so most of these depend on the view of the person, it all depends on how you interpret things.

The Chinese word for "Contradiction" has the literal translation of "Spear-Shield" - 矛盾 ;

As it relates to the tale of a boastfull blacksmith - who claimed that his Spears could pierce any Shield and that his Shield could deflect any Spear.... then someone asked "What happens if I wear your shield and get stabbed by one of your spears?"

Alot of the Chinese language is like that - seemingly unrelated words coupled with a historical back-story to create a new interpretation for those words... it's a confusing language to learn.


It's a similar paradox to "What happens when an irresistable force meets an immovable object?"

A combination of the phrases, a cat always lands on its feet, and toast always lands buttered side down: If a cat has a piece of toast, buttered side sticking up, strapped to it's back, what side will the cat land on?

The cat will land on its feet. It's not a paradox; the only reason toast usually lands butter side down is because the height toast is usually dropped from is only far enough for half a rotation. Drop it from twice as high and it'll land butter side up.

Obviously if it's on the back of a cat it won't rotate at all, unless the cat decides to do some somesaults and stuff mid-fall.


Similarly, if you butter both sides of a piece of toast, which side will it land on?

The side that is on the bottom just before you drop it.

No, honestly - it "really" does depend on what height you drop the cat from;

In a sample study of 115 cats that had fallen out of high-rise windows - only 5% of cats that fell out of windows from between 9 and 32 floors high suffered fatal injuries, compared to 10% fatalities for Cats of lower than 7 floors high. Also the cats that fell from a higher height suffered less serious injuries than those from lower floors, sustaining only fractures rather than broken bones.

I am not aware of any similar studies done on buttered toast
