Re: 5D Black Holes
Our universe, which according to this is simply a "sphere" of material slowly escaping from a dead hyperstar's black hole, has its size increase as it escapes the black hole

I am curious: does this imply that our universe is, in and of itself, a 'bubble' within another four dimensional universe of some type?

I'm also a little confused with regards to three dimensional universes versus four dimensional universes. Is the 'fourth dimension', as implied in this case, not the dimension of time but something else? And a final question: since space-time is a fundamental construct of our universe, isn't our universe already a four dimensional universe?

Re: 5D Black Holes
In my post I said that I wouldn't include time, as it wasn't necessary to understand this model. However correctly our universe is 3+1-dimensional. This model says we might be a bubble in a 4+1 dimensional universe.

That clears things up. I appreciate the clarification.

I have no idea how another spatial dimension would manifest, but then again, I am not a four dimensional being!

It makes me wonder: if our universe (3+1) is essentially a 'bubble' within another, larger (4+1) universe, are there other (3+1) universe bubbles also in existence and if so, can they interact? i.e. collide?

Re: 5D Black Holes
Have you read Flatland?

Have not read it, but I know of it. They actually indirectly referenced the concept in one of the episodes of the Big Bang Theory.

That reminds me: I recall reading a sci fi short story years ago about a vacuum instability event (I think that is what they called it) where the universe's inherent 'energy state' actually shifted. (Like an electron changing energy states) This changed the fundamental laws of physics in the universe and most advanced devices stopped working. Interesting take on a theoretical premise, although I believe even a minor shift in any of the fundamental forces would basically negate all current life and drastically change the nature of the universe as a whole.
