Several cosmologists, including Hawking, have developed the idea that
this means that the Universe is a black hole -- we are living inside an
extremely large black hole, and will one day suffer the fate of any
matter inside a black hole, as spelled out by Penrose thirty odd years
ago. So cosmologists have recently puzzled over what happens at the
singularity at the end of time, the Omega Point. The obvious guess is
that the singularity that marks the death of our Universe marks the birth
of another universal cycle, and this is born out by the mathematics.

But if one singularity can give birth to a Universe, why can't others?
Specifically, what happens at the singularities that form inside black
holes in our own Universe? According to some interpretations of the
equations (and here I have to admit that not everyone agrees on this),
the singularities could form their own baby universes. On this picture,
stuff that falls into a black hole singularity is shunted sideways into
another set of dimensions, its own spacetime. It sounds like science
fiction, but it isn't really--science fiction writers are never as imaginative
as mathematical physicists. Hawking's baby universes are rather like that,
little bubbles on the surface of the expanding balloon, each expanding in their
own right, still connected to the mother Universe by a "wormhole".

And, of course, the baby universes can have babies of their own, while
our Universe may be the offspring of a black hole that formed in
another spacetime. Very quickly, the picture in your mind comes to
resemble a mass of expanding frogspawn, or the froth of a bubble bath
being whipped up ever higher.

This sounds similar to Black Hole, the piece, in which stuff falls into the
singularity & then is spit out--but Hawking says it is spit out into another
set of dimensions.

At least Hawking believes me.

Music and the dixieland/quantum uncertainty:
Whatever you think about free jazz, it matches in energy and uncertainty the quantum mechanical universe. Think about how to play free music and it comes off more spacetime than subatomic, more Einstein & less Pauli, more Freud and less Jung. Dixie is like controlled chaos. Jazz varies between controlled chaos and uncontrolled Feynmania. Raise the energy until it all falls apart--free jazz.
