Yes, but what does that mean??

A team of astrophysicists at Canada’s University of Waterloo have put forth a theory suggesting that our universe exists inside the event horizon of a massive higher dimensional black hole nested within a larger mother universe.
Perhaps even more strangely, scientists say this radical proposition is consistent with astronomical and cosmological observations and that theoretically, such a reality could inch us closer to the long-awaited theory of “quantum gravity.”
The research team at Waterloo used laws from string theory to imagine a lower-dimensional universe marooned inside the membrane of a higher dimensional one.
Lead researcher Robert Mann said:
The basic idea was that maybe the singularity of the universe is like the singularity at the centre of a black hole. The idea was in some sense motivated by trying to unify the notion of singularity, or what is incompleteness in general relativity between black holes and cosmology. And so out of that came the idea that the Big Bang would be analogous to the formation of a black hole, but kind of in reverse.”

Nikodem Poplawski of the University of New Haven imagines the seed of the universe like the seed of a plant - a core of fundamental information compressed inside of a shell that shields it from the outside world. Poplawski says this is essentially what a black hole is, a protective shell around a black hole singularity ravaged by extreme tidal forces creating a kind of torsion mechanism.
Compressed tightly enough - as scientists imagine is the case at the singularity of a black hole, which may break down the known laws of physics - the torsion could produce a spring-loaded effect comparable to a jack-in-the-box. The subsequent “big bounce” may have been our Big Bang, which took place inside the collapsed remnants of a five-dimensional star.
Poplawski also suggested that black holes could be portals connecting universes. Each black hole, he says, could be a “one-way door” to another universe, or perhaps the multiverse.
Regardless of whether or not this provocative theory is true, scientists increasingly believe that black holes could be the key to understanding many of the most vexing mysteries in the universe, including the Big Bang, inflation, and dark energy. Physicists also believe black holes could help bridge the divide between quantum mechanics and Einstein’s theory of relativity.

But, do we really want to do that?  Questions, questions....

  3. Questions are good, we are slowly learning which questions to ask.

  4. OK. But how much acid did they drop to come up with this idea?

  5. So a lot of that multi-dimensional science fiction I read in the 50's and 60's may be true? How about "The Underverse"?

    1. The Underverse exists on the label of Sans' underpants.

  6. And not one iota of credit given to Kamala Harris for her black-hole contribution. Shameful!
