Recursive holes in space sounds fun.

spacetime curves into >= hole >= singularity =< hole <= out from curves spacetime

simultaneously. But from our perspective 'our' universe is expanding.

Wish I knew cool maths to go deep in quantum physics.

Yes, this is absolutely what I spend my time on at a Saturday evening.

So I'm thinking.. as matter 'falls' into singularity, if it's the case that even quarks finally gets teared apart, that means energy are put into that local system, resulting in more quarks. If this happens as matter is closing in on the singularity, it seems intuitive to me that where "time" faults, space emerges on the other end and new time therefore exists again.

From our universes' perspective that would look like .. well.. an ever expanding bubble, right? Dark energy and matter just being left over energy from a new emergent spacetime.

As soon at the outer universe empties out, an inner universe would deaccelerate, eventually resulting in all matter falling into the larger black holes, merging. Our "13.5B years old" universe might not make sense from a perspective of time frame in any outer or inner universes.

So, if we have multiple ultramassive black holes, eventually merging, the size of any white hole might not be ratioed per time, as matter falls in they both accelerates towards c, and gets spaghettified, from the point of view of an emergent universe this might seem to happen linearly, of from a singular space/time (hence a big bang model). So what if our big bang is just and incomprehensible compression of spacetime from an outer black hole, and as the white hole emerges, it seems to originate from a single point, even though this single point is also spacetime coming into existence, so it was never a point in space, it is space, and therefore any measurement from "outside" the emerging spacetime does not make sense. "What are the universe expanding into?" might just be undefined. Just because humans can construct a sentence doesn't make it valid.

Again, I don't know the technicalities and maths to understand these things, just thinking.

Hmmm, LQG, AdS/CFT, ER=EPR, spin networks, causal dynamical triangulations...

Good thing I have Claude to ... er, I mean a beard to scratch and ponder this myself. Nah.. AI is great compared to classical information searching.

Happy caturday 🖖
