I like the one where we live inside of a black hole, and a black hole is a gateway to another universe

Not the most useful of gateways though if you have to be smushed to go through it.

Think of the weight loss bro better than any diet

I believe the correct term is "spaghettification" and it's not your ordinary everyday spaghettification, but one that happens at an atomic level.

As I understand it, spaghettification only happens falling into a "small" black hole, the difference in gravity is huge over a small enough distance to stretch you into meat goop as your corpse fall towards the singularity.

A supermassive black hole like in our and most galaxy centers, you'd cross the event horizon without noticing anything different besides tunnel vision. But yeah. It'll end with total obliteration.

Makes sense tho, there's not much complexity to the material expanding from the big bang initially. Squished into almost nothing and squirted out the other end completely unmade is not great sci-fi :(

As long as you find a black hole that leads to the spaghetti universe, it would be fine

It's this theory here:

https://en.wikipedia.org/wiki/White_hole#Big_Bang/Supermassive_White_Hole

edit: While I do like the idea I hadn't begun to take it seriously until this news about our Universe possibly spinning. It's one of the few properties of a black hole. The only other possibly persuasive bit of info I've personally heard about is that heat death seems awful similar to how black holes evaporate (Hawking Radiation) somehow apparently. I won't pretend to understand that one. But! To my mind, that would mean this universe is a one and done deal. No infinite cycle.

Still doesn't preclude an infinite cycle, so long as Nothing is unstable.

I think another point is that the edge of our universe is thought to behave in the same way as the event horizon on a black hole

[–] [email protected] 1 points 1 month ago (1 children)

If it ever turns out to be true (I'll be long dead) that might start to answer my previous question here about what would happen if our black hole was actively or suddenly started consuming matter in the universe or whatever above ours. Still not comforting is the idea of our black hole merging with another.

The mass has to go somewhere by logic but I don’t know enough about it, but it would make sense for all that mass to be taken elsewhere
