Paradoxes
I was reading this article on WIRED.com, and it had me thinking about some paradoxes. Post your favorite ones here.
- Before an object can travel distance D, it must travel distance D/2. To travel D/2, it must travel D/4, and so on. This means the distance D can never be traveled. |

What would happen if you are going the speed of light and turned on your headlights?

Re: Paradoxes
As I recall things, since you can't go the speed of light, it's immaterial. However, even if you're going 99.9999% the speed of light, you'll always measure the speed of a beam of light you fire as c. The relativistic time and space effects warp things so that this is the case.
Godel's Incompleteness theorem always amused me, even if it's not actually a paradox. It states that any consistent sytem of rules, etc must contain statements that can't be decided. The classic example from logic being: This statement is false. The colloquial version from Mathworld is amusing: "... any formal system that is interesting enough to formulate its own consistency can prove its own consistency if and only if it is inconsistent." |
Re: Paradoxes
Heres one for ya.
Your in a space ship, going faster than light traveling away from the earth. You look through a powerful telescope back at people on earth. What would you see? if anything at all? Would it appear that people are moving in reverse? Tricky eh On a similar note, same scenario, except you look away from the earth. What would you see? Since your traveling faster than the light traveling in the same direction as yourself, you would be catching up to them... so would you be able to see things that are happening behind you? Very Tricky |

In the interest of melting a brain or two, please consider "The least integer not nameable in fewer than nineteen syllables." A phrase that itself has only 18 syllables.

A Ham Sandwich Paradox
Which is better, eternal happiness or a ham sandwich? It would appear that eternal happiness is better, but this is really not so! After all, nothing is better than eternal happiness, and a ham sandwich is certainly better than nothing. Therefore a ham sandwich is better than eternal happiness. Confused? |

But fear not! All will not be blackness. As the formerly visible light fades from view, ultraviolet, x-rays, and eventually gamma rays will come into view as visible light. Now that would be cool: being able to see x-rays with the naked eye just like Superman! |
