Hello all. This is my first post here, so I hope I don't do anything wrong. I would have posted this in a general 'quick question' forum if there was one, but I figured this would be a good place to ask.
So, I've been trying to understand this for a long time, but so far, no one has been able to sufficiently explain it to me. My question comes down to this. Since quantum theory tells us, there is a smallest significant distance; the planck distance, and thus a smallest possible significant time (The time it would take to move over a distance of 1 planck distance going with the speed of light.) how would 'change' then be possible? What I mean by that is, that as I understand it now, when a shorter time passes then the planck time, nothing can possibly have changed right? So, you can imagine it like still frames of 1 planck time 'width'. But when you put all those frames side by side you would have one from where everything stays the same, then, directly following that, is the next frame, where again, nothing can change, and so forth. But when we experience the real world we see change and motion all around us. So there is a paradox.
I'm guessing I'm misunderstanding the basic concepts here, since that's what happens with most paradoxes, but if not, my other alternative explanations were:
1, Maybe the uncertainty principle makes it possible for something to happen, since the event happening or not is not at a certain point in time, but rather smeared out having probaballistic properties? 2 Maybe, the change occurs instantaneously in between the frames essentially making time grainy and pixel like? (Which would not affect our macro observations) I really hope someone can explain this to me. Also on a related question. If massless particles always travel with the speed of light, how does a photon get reflected then? Since at one instant, it travels with lightspeed in the positive direction, and an instant later it would travel with light speed in the negative direction. Or,... there would be a moment in between where it's speed would be 0? Very confusing to me. Please let me know. Thanks
