That's putting it mildly. I was thinking that it is more likely that a
universe tunnels out of a black hole that "just randomly" happens to contain
your precise brain state at that moment, and for all of future eternity. But
the majority of these random universes will be precisely that; random. In
most cases you will then find that your immortal experience is of a purely
random universe, which is likely a good definition of "hell".
