Well, why not? Why shouldn't a cause happen after the event? — Banno
So far we know that the universe is deterministic, our known universe has a set axis of time. However, it seem to be based on the properties of probability. The larger the object or space, the more probable the consequences of causes becomes. The smaller you go, down to the quantum level, the less probable it gets. Now, by "large objects" I don't mean suns and galaxies, but even ourselves. You need to go down to extreme small scales before the quantum behaviour breaks down things.
But here lies a contradiction of sorts. If the universe is deterministic, how do we know that the quantum randomness aren't causes in a chain reaction of events? If you could predict every particle in the universe, that would mean you could predict all outcomes of all movements and states, but because you cannot predict quantum level events, since they are random, how then do we know that the consequences aren't affected by randomization on the quantum level?
If a large object in space, say, an astroid, speeds through space, it gets attracted and accelerated in different directions throughout it's journey, changing it's path slightly but so much that further down the line it's changed course by millions of light years. If random events on a quantum level change that asteroid's trajectory by a margin that is almost not measurable, it would still have changed the location billions of light years of travel later.
Now, I'm pulling hypotheses from educated guess work here since I'm not a theoretical physicist. Maybe the quantum level is random but cannot change the deterministic nature of the larger world since the only way for it to truly change the course of the asteroid is by expanding the randomness into observation, into levels of probability in which the randomness becomes so high in probable conclusions that it won't change the trajectory. Maybe the randomness and low probability of the quantum level through the process of going from 0% probable to 99,999999999999999999999999% (infinite decimals) probable, is part of how causality and entropy works and therefor the deterministic universe is still solid. If the randomness on the quantum level cannot effect movement of mass, it won't move particles of mass, but only charge their state.
So, as said, hypothetical guess-work here. I still don't know enough of things like Higgs fields and particles and there's also that little thing called unification theory that we haven't solved. However, while it's chaos on the quantum level it doesn't effect us on the larger scale. The general laws of the universe starts breaking down at a quantum level, but the laws prevents things to move backwards in time on any scale larger. I mean, we could also talk about the state of light, in which the speed of light makes only us experience light. Light in itself does not have a concept of time, since it's the speed of light, so at the start of it's journey it has already reached it's destination at the same in "it's own perspective". Because everything else is slower than the speed of light, we witness things going slower, but if you were speeding at the speed of light, you would be at the start and end of the destination at the same time, since time stops at that speed and would have been like that since the dawn of our universal laws.
Both at the quantum level and at the speed of light or at the maximum gravitational force exceeding lights speed, things break down and our laws of the universe cease to work in the way we perceive it. The big question is; if we had the means, could we make us perceive things outside of the perception we are slaves under now? Or are we forced to only understand as far as our perception goes? Even if we prove things like tachyons, would we fully understand them? Or would all the data get scrambled into a mess since we have no framework existing in our universe to even explain the basics of them?
If we live on a scale, at a slower speed than light and under normal gravitational conditions, the probability of events going against the laws of the universe are 99,9999% with infinite decimals. If there was a slim chance of a consequence causing a cause, that seem to never be, because infinitely unlikely that it will happen. It's that mind boggling thing in math where there is a chance of something, but a version of "infinite" makes it infinitely unlikely, even if it is likely.
But I'd rather point to a theoretical physicist on all of this, I can barely calculate basic math
