Can an object be infinitely small? IE if I took the smallest thing known to man (quark) I think, it may not be possible today but in theory, a quark could be split in half, and then in half again an infinite amount of times? Or is there a proven fact that states the smallest size an object can be until it's literally so small it'll just vanish and that particular object no longer exists. I read somewhere that there's actually the smallest distance which something can move. Because everything moves in frames... kinda like a slide show? Obviously though the amount of movement from one distance to another is so tiny you couldn't possibly notice it.
