And early in Big Bang when the cosmic fireball was at the Planck
Temperature of 1.41*10^32 degrees Kelvin how does Russell propose the
information was encoded?
High temperature means there are lots of states energetically available,
so it doesn't preclude high information content. If quantum mechanics
is right then the physical evolution of states has always been unitary
and reversible and information has been preserved.
That still leaves the coding problem -- just think Hawking radiation.
But information is preserved only in the multiverse. It most certainly
is not preserved in the universe we observe.
