      Paradoxes

      If you went back in time and killed your grandfather, you wouldn't exist, so that means you couldn't have killed your grandfather. So that means that he would never die back in time.

      Do you have any good ones?

      Hey guys, I'm back. Feels good man

      This only arises if you were to go back to the same dimension. Theoretically, if time travel was possible, you would go to a separate dimension and time-line similar to our own, but not quite the same. Thus this paradox would never arise.

      Curry's paradox:

      If this sentence is true, then Santa Claus exists.

      There are variations such as "If this sentence is true, then the world will end in a week".

      The paradox is that the sentence could be true because because its just saying that if it is true then something will happen. The sentence is true in making such a statement and therefore Santa should exist and or the world should end.

      Like every Paradox it is flawed but still interesting to think about.

      Edit: Heres another good one I found on wikipedia:

      "Exception paradox: if every rule has an exception, then there must be an exception to the rule that every rule has an exception."

      http://en.wikipedia.org/wiki/Exception_paradox

      Obvisouly the Cretan is lieing...so that makes him the only liar and all other Cretans don't lie.

      Behold: the palindrome video. The song is called "crab cannon" and is exactly the same backwards as it is forwards.

      Grod is right, going back in time doesn't represent our reality as the consequence of your actions continues in an alternative parallel world and not in this world.

      You can't really know unless you have time traveled before. I could claim that the universe is at equilibrium and would stop a time traveler from creating a paradox, a bit like Le Chatelier's principle in chemistry. Just an example though, as of now there's no way for us to know.

      Here's a paradox: Imagine a hotel with an infinite number of rooms, even if it's full it still can take in guests.

      Yes, but we can theorize by studying the way our world is made up, and the way we perceive it.

      Who knows, we might know someday, maybe not in the next twenty years, or a hundred, but I'm not counting the possibility off yet.

      But it would never be full.

      It would, but it would still have room too. It's a paradox. =p

      Not really. If it had infinite rooms there'd be an infinite amount of people to fit inside, meaning that the hotel would never be full. Sorry bud.

      But it does illustrate the impossibility of going back on the same timeline.

      What if it is given that every room has a person in it?

      That is my favorite paradox, and I have spent a lot of time wrapping my brain around it. I think it actually disproves one of the supposed laws of logic, the "law of the excluded middle". "Either P is true, or P is not true." Another way of expressing it is, "A or not A." The paradox you posted seems to be an exception to that rule, which is so fascinating but sort of sucks because I have used the rule to back a ton of my internet arguments. Think about this:

      Either the sentence is false, or the sentence is not false.

      If it is false, then it is not actually false, making it a true statement. If it is true, then it really is false, making it a true statement, so it is false. If false, then not false. If not false, then false. It is not either or. It is simultaneously two contradictory things. I really think that paradox disproves the law of the excluded middle. It is in that middle that is said not to exist. It honestly makes me question reality more than anything else I have ever come across.

      Eigen's Paradox effectively argues that life could never exist. As paradoxes go, that's pretty powerful...
