These strange things happens, as I understand it, ON the event horizon.

If I ever make a mod, it will be a spell, called, "On the (event) horizon". It will require A1E1W1F1N1B1D1A1 and cost 40 astral gems. The effect will be to destroy every single building (temple, castles and labs). And maybe all people too.

Given that the thermal energy of the black hole would be associated with matter, and the matter of a black hole is contained within the event horizon any radiation would be contained within the event horizon.

The thermal emissions I learnt were associated with black holes are those from acceleration effects on matter. For instance a star/black hole orbitting each other, with the hole pulling matter from the star, which then spirals around the black hole until it dissapears into it. Radiating quite a lot as it does.

I may be wrong here, but I think based upon what I've read, that at this moment the "string theory", as scintists understand it, is not really a single all-incorporating and explaining neat theory which is more or less universally accepted, but rather a collection of related theories based upon variations of "hyper string" concept, some of them being more admited by the scintific world than others.

Hmmm inst that true of any theory? Generally scientists have no problem with the word theory. Its only the people outside the Sci world that want to declare things too soon as "fact". Even things that have the word theory in their name.

Ultra strictly you can never proove a theory. Each time observations agree with the theories predictions you are more certain it is correct. As soon as one reliable observation disagrees, you know that it isn't.

I myself don't Subscribe to the Hidden Variable Theory, but I think it is a theory. The variables just have to be currently unobservable, it's perfectly possible that we will observe them in the future, with more advanced techniques.

Schroedinger's cat would make the perfect pet. Discuss :-D

My apology, I was writing the post ~2AM, wasn't thinking straight. Black holes don't thermal radiate like your conventional matter actually.

I was thinking of Hawking Radiation instead, which is the virtual particle emission mentioned above. The reason I mentioned thermal emission is that historically, it was the nagging concern that if black holes do not radiate, it would be an entropy destroyer of the cosmos, something thermodynamics do not allow. So people think black hole must radiate somehow, and then Hawking Radiation was proposed to solve this.

My apology for the misleading information. I'll edit my previous post appropriately.

And Schroedinger's Cat may or may not be the perfect pet. It depends on what the first observation reveals
