Extraordinary claims require extraordinary evidence. Also what happens to this "universe" when the black hole dissipates due to Hawkins Radiation?

I thought it was weird that Stephen Hawking wasn't mentioned at all in an article about black holes. But to be fair, I don't think we have any evidence of Hawking Radiation either.

You are quite correct "Hawking Radiation" (entropy) completely blows this (rather fun) theory to pieces. Nice idea but does not stand up to inspection.

I rather think that there is such evidence (mostly indirect though). Plus - if folks start creating mini-black holes under experimental conditions then we are all in trouble if entropy does not kick in and cause them to evaporate in pretty short order.

Well I admit I'm mostly a "Wikipedia physicist", and the lengthy article there says that the effect has not been observed. If you find such a citation, might I suggest that you add a link? http://en.wikipedia.org/wiki/Hawking_radiation

The idea of the big bang being caused by some sort of 'white hole', is kind of cool. Here you have an object absorbing all matter, becoming infinitely dense, and at some point, it becomes so dense with matter that it actually tears a hole right through the fabric of the universe, where it then diffuses into a new reality where matter is low/non-existant. You'd have to agree that if this is possible, the 'explosion' that would occurr as the black hole diffused through the tear would be terrific. Would it be equivelent to a 'big bang'? I don't know.

Perhaps the life (or death) of a black hole varies, dependent on the available matter for the black hole to consume. A black hole that never reaches that critical amount of mass required to tear through into a new dimension (or whatever the terminology for describing the event is) is doomed to dissipate via Hawkins Radiation, however a black hole that consumes enough matter to tear such a hole, ends up disappearing anyway, as it diffuses into the newly created universe?

I have no idea, nor am I qualified in any way to have an opinion. I did read 'A Brief History of Time' once though!

It is worth noting that the estimated mass of the universe is the same as the mass of a black hole whose event horizon has the radius of the visible universe.

This coincidence is rather striking and has been the subject of much speculation, though nobody has been able to make anything useful come out of it. If this theory manages to predict this relation within the created universe, that would be evidence for the theory.
