Hm, from what I know about physics, time and space are actually much more absolute and inviolable than our imperfect perceptions. the laws are quite different than our intuition, but everything is water-tight and there is no room for any deviation. the smallest of deviations would mean multiple nobel prizes, so ppl are searching really hard to find any, without success. On the other hand, if we talk about our perception, the things we see around us are of course a virtual reality constructed by our brain to model the input from our sensors, but this is normal because there is no alternative. But it seems to me you are saying smth different?
