The laws of physics are time-symmetrical. This is true for both classical dynamics and quantum mechanics.
Various attempts have been made over the decades to try to come up with a deeper understanding. Examples include String Theory, Loop quantum gravity, and computational models such as those espoused by Stephen Wolfram.
What they all seem to lack however is a recognition of the intrinsic reversibility of the universe we live in.
In my opinion, the most promising research in this realm is actually around Quantum computation. By necessity, it accepts the reversibility at the heart of things, otherwise you couldn't have the sorts of logic gates you need to do Quantum computation.
By way of an entrance into this rabbit hole, look up the Ffredkin gate.
