How 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?

Perhaps dark energy is hawking radiation. We just see what it's like from the inside.

Something to consider is a possible time scale difference. Eg time could be dilated for us for being around so much density.

It would need to be the other way around, dark energy being matter falling into our black hole. Hawking radiation should 'suck' energy out of our universe. I can't think of a satisfying source of this energy. The best I can imagine is either space contracting (but that is gravity) or entropy increasing (but that doesn't leak energy, just free energy).
