**Ask a monkey a physics question thread**

[rong]

This may be a dumb question as I know nothing on this subject whatsoever. But is there any evidence to suggest our universe is not the inside of a black hole. I mean the big bang sounds like a star imploding/exploding/whatever we call the creation of a black hole and the universe expanding sounds like it fits the theory of a black hole sucking stuff in as it grows. Is this not the most obvious theory of our universe? Does anything prove/imply/suggest that this isn't the case?

I may have asked this before, I've asked it before somewhere and don't remember getting a satisfactory answer.

In post #20, you asked:

Are we inside a black hole?
This seems to me to be the most obvious explanation of our universe.
Is there any evidence to suggest we aren't?

In post #30, my response:

Physics answer: could be
Nothing can be observed beyond an event horizon, and therefore it is outside the purview of physics. We don't know what happens inside black holes, so it is impossible to rule out that the entire universe is, in fact, inside a black hole.

As stated, there can be no physical evidence for or against this claim.
