But wouldn't that mean it's black holes all the way down? If in our universe, another universe is inside every black hole, then aren't those universes quite small due to their total mass being the same as the black holes'? The mass of black holes can be quite modest. Then the universes inside those universes' black holes would be even smaller, and so on. Also, it's my understanding that black holes shrink over the time, so they aren't expanding and certainly not at increasing rates like our universe is. The ones in the center of galaxies "gobble" up gas, but most black holes aren't at the centers of galaxies.

> The ones in the center of galaxies "gobble" up gas, but most black holes aren't at the centers of galaxies. Most black holes aren't as large as our universe, although if that theory is true we can't say much about what a typical black hole would be like in the larger universe. It is also possible our universe ate the entire outer universe. At a certain size the black holes density is less than the universe density, at that point its event horizon will expand forever and eat the whole universe. That could happen to our universe as well. That probably wouldn't destroy the outer universe though, since entering such a large black hole doesn't rip you apart, so in a way that is a theoretical way to "exit" a black hole, although technically you make the outer universe enter it. Edit: Back in college I intend to go into theoretical physics, but once I got to string theory etc I no longer believed in it, and continuing from there would mean I'd have to study that sort of nonsense for half a decade just to enter the field. That makes theoretical automatically turn away anyone who have alternate interpretations, so you wont find them form working physicists. I know all the math from the tested parts of GR, the rest are just untested theories, mine are as good as any there.
