Could we be living inside a super-super massive black hole

Black hole the entire mass/energy contents of our entire universe?

Such a universe would have a radius about the size of our universe and density about our universe!

It seems possible. However, it is more likely in my opinion, that we are currently inside a white hole being accelerated toward a black hole event horizon where sometime later, a new Big Bang Universe will emerge.

Now imagine that the white hole / black hole event horizons somehow folded back onto one another forming a ring like universe. See: Wormholes - P1

I don't think that is quite accurate. Black Holes, by definition, has super dense mass. The mass of our universe is the exact opposite of that. Tiny specks of mass in a giant near mass-less space (dark matter not included.)

If we DID live in a super-super massive black hole, we would live on one super massive, giant ball of dense matter (with temperatures reaching billions of degrees, and pressures millions if not billions times the force of gravity.)

A few scientist have indeed postulated that this could be so. The say we are inside a Grav Star with mass centered @ the outer edge. As we we move outwards to the edge of the Grav Star our speed is accelerating This is supported by our measurements that the universes expansion is accelerating pace equally in all directions. It has been also suggested that BH spawn other universes.....multi-universe theory

Some scientists believe that that is possible.

As some other answerers have pointed out, light can not escape from a black hole. However, there is no evidence that light is escaping from our Universe, so that is not a reason why our Universe can not be a black hole.

According to Stephan Hawking "light cannot escape, neither can anything else; everything is dragged back by the gravitational field." (Hawking, 1988), so this would seem that there is a center to which everything is being drawn to, except we are observing that our universe is expanding, therefore not being dragged back by the gravitational field.

Oh yeah, we live in a black hole. That`s why the universe is expanding... it`s gobbling up nonexistence. Very plausible.

Nope!

we live but around that black hole not inside
