Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and
makes a universe for them to describe?

I'm sorry to disappoint science fiction fans, but if information is preserved, there is no possibility of using black holes to travel to other universes. If you jump into a black hole, your mass energy will be returned to our universe but in a mangled form which contains the information about what you were like but in a state where it can not be easily recognized. It is like burning an encyclopedia. Information is not lost, if one keeps the smoke and the ashes. But it is difficult to read. In practice, it would be too difficult to re-build a macroscopic object like an encyclopedia that fell inside a black hole from information in the radiation, but the information preserving result is important for microscopic processes involving virtual black holes.

People who boast about their I.Q. are losers.

Why are we so worried about artificial intelligence? Surely humans are always able to pull the plug? People asked a computer, ‘Is there a God?’ And the computer said, ‘There is now,’ and fused the plug.
