Hypothetically, could the interior of a black hole look exactly like the universe that surrounds us?
I do understand that we can't experimentally verify anything we imagine about the interior of a black hole.
If we were to apply what we know about the physics of the observable universe and assume ...

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 ...

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 ...

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 ...

What will happen to a naked singularity during the Big Rip? [duplicate]
I apologize in advance if some concepts I use are vague, but I am just an enthusiast.
I have read that the Big Rip will not rip off black holes because the event horizon will become equal to something ...

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 ...

Why did the universe not collapse to a black hole shortly after the big bang?
Wasn't the density of the universe at the moment after the Big Bang so great as to create a black hole? If the answer is that the universe/space-time can expand anyway what does it imply about what ...
