What is cool about Life 2333 is that it is irreversible.
Each current state leads to one and only one state on
the next iteration, but the current state could have come

people regard as "the laws of physics" are almost all
time reversible.

Still if you were to reverse the Universe which would
involve reversing the velocities and direction of gravity
and electromagnetic forces the computer on which Life
runs would be reversible?

If you release a ball on the side of a bowl it will roll
around until friction brings it to a halt on the bottom.
You cannot reverse the state (ball on bottom) to the
state that lead to that final state. But if you reverse
the Universe the forces that were dissipated as friction
would also reverse pushing the ball back to whatever
state it started with?

So it is the macro description that is irreversible not
the physical reality. We have lost the information but
the Universe has not?
