Is our universe trapped inside a black hole? This JWS Telescope discovery

> 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?

(Complete hypothesizing from a very cursory understanding.)

Perhaps that's dark energy or vacuum energy? If mass and time truly switches places when crossing into a black hole, it would make sense that the spacetime size of this universe translates into observable mass outside it. Which might tie it to the expansion of the 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.

What do you mean by that?

The relative time part is a really interesting thought. Thanks!

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.

Time in high gravity usually flows slower than in flat regions, not faster.

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

With our math, yes. But maybe that’s because we are the imaginary part of the equation.

what exactly is a flat region in high gravity?
