I hate thinking about free will in physics. It's a real conflict for me. On the one hand, I think the universe is completely deterministic, while on the other it horrifies me to think I am not in control of my future. I kinda don't want science to resolve it for me, because either way I'd be unhappy.

On another note, I've been thinking about the heat death of the universe, something else I've always felt uncomfortable with. I propose that the second law of thermodynamics actually forbids heat death. Here's why...

The entropy of a system always increases with time. That's the 2nd law. But heat death is the spreading out of all energy into perfect equilibrium. The "final state" of the universe is pure radiation. But radiation moves at light speed, and therefore has no mass. So the final state of the universe is massless, and therefore lacking in gravity, which critically implies no time.

With no time, there is no space. So it is meaningless to say there is space between each unit of energy. This makes the end of the universe indistinguishable from the beginning of the universe, where all energy was compressed into a singularity. A universe with no time is a singularity.

Heat death implies a new big bang. And the big bang is as low entropy as possible. So the 2nd law is broken, entropy decreased.
