As far as i understand, we (our mind) observe the universe at set periods of time, say, our consciousness activates each 0.5 seconds for instance.
This means that we have no perception whatsoever of what happens between the 0.5 seconds that exist between our perceptions.This led me to the question: can we be 100% sure that, for instance, when we see a body B moving from point 1 to point 2, it actually moved across a straight line? Or could some very strong force have moved it backwards behind point 1 at some instant, and then some other even stronger force moved the body to point 2? In the end, we would still believe that the object took a straight path, but we have no way to know!
Is there some law in physics that invalidates this? Otherwise we couldn't be 100% sure when we make statements like "John was here (America for instance) with me during the last 10 minutes, so he couldn't be in China 5 minutes ago as you said". Since John could indeed have been in China between our perception instants.
Thanks in advance
