> These [baby] universes would be unobservable to us because they are also behind an event horizon, a one-way light-trapping point of no return from which light cannot escape, meaning information can never travel from the interior of a black hole to an external observer.

Also meaning that “our” blackhole (the one containing us) is unobservable from the parent universe for the same reason. So where is all this extra light/energy going in our universe? Should we not have detected an increase of energy in our universe?

I figure our whole universe so far has existed in the first nanosecond (or whatever) after the creation of the black hole in the parent universe, so very little energy or light has had time to enter.

By one or two seconds in the parent universe’s time scale, our universe will have settled down to its extremely long state of being a cold, dark void of slowly decomposing subatomic particles.

No good reason to think this, just feels right.

Scales are a very interesting thing to think about. There's a theory that the universe didn't really 'start' with the big bang, that it was always there, but at a different scale. The big bang was essentially an increase in the scale of the universe, possibly in terms of time and space.

Our universe may be a rotating detonation engine only it's our universe being made not combustion.
