Black holes may harbour their own universes

Black holes may contain whole universes inside them, according to a theory called loop quantum gravity (Illustration: XMM-Newton/ESA/NASA)
When matter gets swallowed by a black hole, it could fall into another universe contained inside the black hole, or get trapped inside a wormhole-like connection to a second black hole, a new study suggests.
What's inside a black hole is one of the biggest mysteries in physics. The theory that predicted black holes in the first place – general relativity – says that all the matter inside them gets squashed into a central point of infinite density called a singularity. But then, "things break down mathematically", says Christian Böhmer of University College London, in the UK. "We would like to see the singularity removed."
Many researchers believe that some kind of new, overarching theory that unites gravity and quantum effects will resolve the problem. String theory is the most popular of these alternatives.
But Böhmer and colleague Kevin Vandersloot of the University of Portsmouth in the UK use a rival approach called loop quantum gravity, which defines space-time as a network of abstract links that connect tiny chunks of space.
Loop quantum gravity has been used before to tackle the singularity that would seem to have occurred at the origin of our universe. It suggests that instead of a big bang, an earlier universe could have collapsed and then exploded outward again in a "big bounce".
Bizarre solutions
A similar repulsiveness appeared when the loop quantum approach was previously applied to the inside of a black hole with particular properties. Those studies suggested there was a repulsive boundary that blocked matter from clumping together in the singularity.

So we may actually have life in these parts??
Some think our universe, AKA the universe, is the inside of a black hole.
Any volunteers to go check it out?
In next 1,000 years, we might be able to do so.
I have an entire galaxy contained inside a locket on a gold chain. Sometimes I let my cat Orion wear it just for kicks.

They controlled a wormhole, and there were ‘entities’ living inside.
Science fiction - as much science as fiction!
Of course they do, what did they think was contained by black holes?
So, each “universe” is the inside of another black hole, and on and on and on, like those boxes in novelty stores that fit inside each other sequentially until they are very small....
Bump for later
But “our” universe is expanding. So, what is it expanding into?..................
Some black holes do not contain universes. Washington, DC is an example.
Interesting. I’m not a scientist but I did stay.....never mind.
I have to wonder though, IF our universe were to be contained in a black hole could an explanation spring forth from that assumption that would explain the apparent but not confirmed existence of dark matter?
Anyone? Bueller?
Like those nested dolls they used to make in Russia. Could be a hundred billion or a trillion universes inside this universe and we can never make contact. Of course we can never make contact with the trillion universes inside of the great universe along with our own universe. It goes both up and down the scale forever, which is as far as we need to think about it: unlimited we can deal with; infinite we cannot—Kant, 1781.
“But “our” universe is expanding. So, what is it expanding into?..................”
Why, our universe, of course.
Look at the ordinary black hole. Is it expanding? Not really, but from inside it could have the illusion of expanding.
So what happens when a black hole falls into another black hole?..................
