Zeno, a famous philosopher back in the days, had a theory that movement was actually impossible for us humans to achieve. For example, you getting up from your chair and going to the door is impossible.

His claim was this:

Before being able to reach the door (our goal), we must be able to stand up and reach our halfway point - correct?

Well before we can reach our halfway point, we're going to have to be able to get 1/4 of the way to the door (or halfway between our starting point and our halfway point).

Yet again, before reaching our 1/4 mark, we'll have to reach our 1/8 point. However, this goes on forever BECAUSE numbers are infinite (right?). So without being able to tell when numbers stop we are unable to begin the actual process of movement.

Anyone have any ideas on how to rebute this? After hearing it myself and going over it a few times, in a philosophical way I believe it.
