(Sorry in advance if this topic has already been covered recently.)
What physical laws distinguish future from past? For example, I imagine some of the laws about entropy would distinguish future from past (like heat spreading). Is there anything besides entropy, and which rules of entropy specifically?
I was wondering if this relates to causality somehow? If the universe is completely deterministic, would there be a way to distinguish future from past or cause from effect?
I'm thinking about the "first cause" argument for God. Some Gnostics believed that God was a "unity". What would entropy and thermodynamics suggest as the starting point - a single bit?
