Pardoxes

Posts: 32
What are your favorite paradoxes?

Examples:

"everything is relative"

"I never tell the truth"

When ever there is time travel you can run into paradoxes. To my understanding of the definition and nature of paradoxes they can never exist and If a paradox is seen it is because we do not fully understand what is going on and once we understand it better it is no longer a paradox. Which leads to my question, is the fact that relativity allows for time paradoxes mean it could wrong somewhat or completely?

If I am misunderstanding the nature of anything in the last paragraph, please explain.

Does anyone know any paradox riddles?

Certainly interesting to say the least as I like me some nice paradox statements every here and then but I don't think this is really the place for that. I mean look at the other threads we have in this forum and ask if a thread about paradoxes should be in here.

Hey, the OP wasn't that bad. I'm not saying it's an awesome thread, but I'm not mad that it was made.

"I never tell the truth"

Not necessarily paradoxes depending on the connotation of the words.

You talk as if it's a given that time paradoxes are possible if relativity is true. This is not so, it would require faster-than-light travel, which as far as we know is not possible. We have theories, but we're not sure if it's physically possible, never mind practical.

My original post falls under the context of science which is an acceptable topic in this forum. I am curious though why would someone who posts about religion, a topic forbidden by Blizzard and not related to science or technology, care?

It is true, however that my two examples do not really have much to do with science; here are some better ones:

When I was thinking of time travel I was thinking of negative energy being used to make it possible. I see your point though.

The context in which I posted them should stand as a paradox for each.

Well do you have a specific question, or do you just want us to come up with paradoxical statements?

I was hoping for a mixture of paradox statements and paradoxes similar to theses :

Infinity Paradoxes
http://www.youtube.com/watch?v=dDl7g_2x74Q&index=63&list=PLt5AfwLFPxWIUYlCb5ip9f_s4qm1zi8kc

Zeno's Paradoxes

Relativity Paradox

and anyone's answer and thoughts to my question:

#1 The talks of religion were ten times more intense and thought-provoking than this silly !@#$

#2 I said look at previous threads and many of the previous threads were about religion so it would've been better if this was another religion so as t spark another debate rather than this %^-*.

#3 Quite frankly I don't know what makes paradoxes so !@#$%-inducing for you

#4 I simply have better things to do than think of paradoxes.

Not really the question I asked. A synonym to the question I ask is: Why would someone who posts off topic care if the subject is on topic?

Topic being technology and science.

Luftwaffe, calm down, if you don't like the thread just don't post on it. You've already made your opinion clear.

Zeno's Paradox is actually pretty solidly refuted by modern mathematics.

The intervals of time get smaller with each division, with the paradoxes which deal with 'moving halfway to the target each time, so there's an infinite number of halfway steps.'

When you integrate the function that you come up with as a result of that, you get it to equal 1.

1/2 + 1/4 + 1/8 + 1/16 + . . . 1/2n = 1

The fact that it's theoretically possible to divide it into an infinite number of subdivisions in no way makes it take an infinite time, as the time for each subdivision approaches zero once you get to small enough subdivisions.

This is coming close to the concept of "infinite but bound."

Zeno's Arrow paradox relies on equivocation; trying to define into existence a 'moment' as a subdivision of time where zero time passes. Relativity gives us a good answer to this; things which experience no time are, by definition, moving at the speed of light and thus massless.

"If everything is motionless at every instant, and time is entirely composed of instants, then motion is impossible."
Quote from Wikipedia page on Zeno's paradoxes

The assumption that "time is entirely composed of instants" is false. For a moment in time or a number in a number line, the former is located in the latter and the former is considered "part of" the latter because it gives meaning to it, but the former does not compose the latter.

Lines contain infinite points.
Areas contain infinite lines.
Volumes contain infinite areas.
4-D spaces contain infinte volumes.

Infinite points do not comprise a line.
Infinite lines do not comprise an area.
Infinite areas do not comprise a volume.
Infinite volumes do not comprise a 4-D space.

In everyday thinking if something is in something else then it is part of it, but this is simply not true for spaces of different dimensions.

I dunno about any really big paradoxes but I do know about the Cadmean Vixen and Laelaps. That counts as one, doesn't it?
