**Ask a monkey a physics question thread**

[MadMojoMonkey]

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.
