#2Ok but then the theory of black holes are wrong because this isn’t dense at all.

#3> 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?

Black holes aren't really infinitely dense. The matter isn't concentrated at the centre, its spread out over the event horizon. As i understand the theory, they effectively suggest you could glue another universe onto the event horizon of a black hole. From the outside that is indistinguishable from 'just a black hole'.

(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.

An entire universe crammed inside the event horizon seems pretty dense to me! Makes you wonder how much matter would be in the parent universe.

#7"All who dare
To cross her course
Are swallowed by
A fearsome force
Through the void
To be destroyed
Or is there something more?
Atomized — at the core
Or through the Astral Door —
To soar…"

#8How does this work with matter falling into 'our' black hole and hawkins-radiation leaving our black hole?
Heck, Hawkins radiation means black holes can evaporate. Does that correspond to a universa collapsing?
Would matter falling into our black hole come shooting out of the white-hole we see?
Would time on either side of the event horizon even be related?

Black holes need not be dense. The black hole at the centre of galaxy M87 has the density of air in our atmosphere. The larger the black hole, the less dense it is. So that alone doesn't preclude us existing inside of one.

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.
