Is there a smallest possible distance or size?

If I'm standing a few yards from a wall, and walk halfway to the wall, then walk halfway to the wall again, then walk halfway to the wall again, ad infinitum, will I ever stop moving? I know from maths that I would only get infinitely close to the wall, but never touch it. However, that means I would never stop moving. If moving any distance requires infinite motion, how is motion possible at all?

conclusion: the universe has a smallest size that can be a distance, like a "resolution"

So just think about this... Atoms are the pixels of real life. Mind blown.
