Thread: Ask a Paradox

Then answer a paradox. I don't care if you steal it from another website, just don't cheat.

Zeno's paradox

One can never reach the end of a racecourse, for in order to do so one would first have to reach the halfway mark, then the halfway mark of the remaining half, then the halfway mark of the final fourth, then of the final eighth, and so on ad infinitum. Since this series of fractions is infinite, one can never hope to get through the entire length of the track (at least not in a finite time).

Start ____________________1/2__________3/4_____7/8__15/16... Finnish

But things get even worse than this. Just as one cannot reach the end of the racecourse, one cannot even begin to run. For before one could reach the halfway point, one would have to reach the 1/4 mark, and before that the 1/8 mark, etc., etc. As there is no first point in this series, one can never really get started.

Each step only takes half as much time as the last to complete, so although there are infinite steps, the infinityth steps take no time at all to run.

Paradox 2:

Time cannot be finite because every cause including the start of the universe is in itself the effect of a preceding cause, but time cannot be infinite because an infinite amount of time would have to have elapsed before now so now would never have happened.

lol that is the logical answer, but paradoxes exist to put a stop to logic.
