Is there any remote possibility that a singularity may be real? [closed]
Usually, when physicists talk about singularities in Einstein's theory of relativity, they say that these cannot exist and that they are only mathematical artifacts that indicate that is likey that ...

We say the big bang (initial singularity) didn't happen at a point, but is it the same with the singularity of a black hole?
I have read this question:
The simple answer is that no, the Big Bang did not happen at a point. Instead, it happened everywhere in the universe at the same time. Consequences of this include
The ...

Do the apparent infinities at the center of black holes disappear if instead a phase-change takes the place of its singularity?
When I watch physics documentaries that discuss black holes, they talk of impossible infinities in the singularity at a black hole's centre.
I was wondering about the bubbles of water vapour in ...

Black hole cosmology vs. Big Bang cosmology
The evidence for Big Bang cosmology is an expanding universe. The expansion of the universe is accelerating. Gravity causes acceleration. What evidence is there that proves everything is moving away ...

Possible Beginnings of New Universes? [duplicate]
Black holes pull anything and everything that enters past the event horizon into the singularity. What if the current unknown output where all of this infinitely condensed matter goes to is the ...

Does time stop inside a black hole? How about at its singularity?
I'm a layperson who just read Brief Answers to Big Question and in the book, Hawking proposes that:
A typical black hole is a star so massive that it has collapsed in on itself. It’s so massive ...

Isn't the Big Bang contradictory with the existance of singularities in black holes? [duplicate]
So it's my understanding that the current models predict that a super massive object will collapse beyond the event horizon into a singularity of infinite density.
My question is the following: isn't ...

Where does the matter and energy go in a black hole?
Is it possible that when matter and energy enter the singularity inside a black hole, that it all re-appears at the big bang?
Some say that black holes will eventually swallow all the matter in the ...

Big Bang not really the beginning of a completely new universe? [closed]
From what I know about the origins of the universe and the big bang, it is stated that it all started from an intensely hot and dense mass. This sounds like a singularity to me, which means a black ...

Black Holes and the Multiverse [closed]
Are there any peer-reviewed theories which explore the idea that black holes in our universe may spawn other universes - or that our universe came from a black-hole-like event in another universe?

How could the "Big Bang" singularity have actually expanded? [duplicate]
We have mountains of evidence about singularities and how they work, and we have mountains of evidence that the "Big Bang" was the origin of the universe as we know it. But if compressing enough ...

Given that matter cannot escape a black hole, how did the big bang produce the universe we see today?
Extrapolation of the expansion of the Universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.
If the matter contained within our ...
