Paradoxes: temporal, logical and otherwise.

So, this is the thread for discussing your favourite paradoxes and answers.

Edit: if anybody mentions the chicken and the egg, I'll be forced to kill you: evolution provides us with the answer: the creature we consider 'chicken' was obviously hatched out of an egg by its evolutionary ancestor divergant enough to NOT be considered 'chicken.' Therefore, the egg was first.

Traveling backwards in time is my favorite.

Asuming that time is linear (and that time travel is possible), traveling back in time is a bit of a mind fuck. Because if you go back in time to do something, there won't be a reason for you to go back in time when you did because there is you already did what you did. So whatever you have done will not happen because it happened. Kinda. Confusing stuff.

Yes, but only if time is linear. I like to imagine time isn't linear. If only to make time-travel slightly more plausible.

Question, how exactly do "contradiction" and "paradox" relate? Is a paradox always a contradiction? Is a contradiction always a paradox? If the answer to at least one of those is "No", then: How to differentiate?

It's more like a big ball of wibbly-wobbly, timey-wimey...stuff

Uhmm... I'm guessing a loop? The rope is completely straight, so it can't be called a <url=http://en.wikipedia.org/wiki/Circle>circle in any case; but the ends of the rope are connected, so I'd call it "a straight loop", however strange that sounds.

Shame on you for stealing Timelord's line : P

Just my words.

If a crocodile steals a child and promises its return if the father can correctly guess what the crocodile will do, how should the crocodile respond in the case that the father guesses that the child will not be returned?

 

[vallorn]

damn. i got thread ninja'd.

i like black holes. they emit no light BUT due to the wierdness of Quantum Mechanics they DO emit something called Hawking Radiation (geuss who thought this up?)

its not realy a paradox but all the good ones have already been taken.

Kill the child and then give him or her back? That way, the child isn't really being quite returned, but also IS being returned. And yes, before you ask, I am indeed a terrible, terrible person.

OT: Well, there's the classic 'This statement is a lie', and that's all I've got for now. This space may be modified later when I'm feeling creative.

Where did he get a talking crocodile?

after changing what you were going to change you go forward and tell yourself to go back and change it. if you do that then it makes perfect sense.

Beat the shit out of the father and take the kid anyway, because that croc's a goddamn REBEL.

Russel's Paradox

Consider the set R the set containing all sets which do not hold themselves as an element. With this statement we find that R is in R but also R is not in R. Both are true, yet contradictory.

consider R in R then R does not qualify to be in R therefor R not in R. If R is not in R then R qualifies to be inside the set R, therefor R in R.

PARADOX

 

[Mikeyfell]

if you have a car
you can replace one part of that car and it's still the same car (right?)
later on you can replace another part of that car and it's still the same (right?)
technically you can replace every part of that car individually and it's still the same car
so what happens if you build a car out of all the parts you took out of the original car?

not that great?

this statement is false

Good one

I've got no idea

Another good one

This then; Is the answer to this question no?

What would happen if you went back in time and killed your previous self?

True. Moving on to the classic "kill your grandparrent" example, no shit would make sense. If you would kill say your grandpa before your parrents where born, you would have never been born to go back in time to prevent yourself from being born. Can't think of anything to make that make any sense at all (still assuming linear time and the possibility of time travel).
