I've heard it said that our our universe is definitely not the inside of a black hole but I have never heard the reasoning for that claim beyond the "maths says it's a singularity". As with a black hole, light cannot escape our visible universe and the inflationary period embedded in the BBT could be interpreted as the initial collapse into a black hole, ie: I like to speculate that it's black holes all the way down (and up, sideways, etc).
Damn, that is what I am also wondering about. Would be really nice to see a good explanation for that.
I mean there must be some relation between the singularity that a black hole is and the singularity at the big bang. In one case the mass collapses and in the other one it inflates and forms a universe. But what is the difference, or isn't there any, and it is just looking at it from outside and from inside?
Below the article here is a link to an article about a theory related to that.. The theory is that the universe is at the surface of a 4-dimensional black hole, which would explain these things. Though I still don't know why it isn't just a 3-dimensional black hole.
