I am a total retard at math and have what is probably a naive philosophical question that either has an obvious answer you all know about or has no answer and is right up there with the meaning of life.

Anyway, as you probably know, Zeno said something like, "Movement is impossible because in order to get from a to b you need to travel half the distance and in order to travel half the distance you need to travel half that distance add infinitum".

Now, mathmematicins answer this with limits but are limits just an abstract concept or is the physical universe a set of infinite limits? I mean, is math in this case just a simplification in order to deal with this problem but doesnt represent the true physical reality of movement?

Sorry if that was confusing :P

Just trying to get my head around what is real and what is just human thought.

And please no pedantic arguments about how real is real :)

Thanks for any insight..
