Stephen Hawking just solved a huge black hole mystery!

[Barn]

Even with decades upon decades of research, this is still a pretty complex theory. Due to the fact that we have never seen a black hole. We have evidence that they exist, and even where they may be located, but we have never actually seen one. So these are pretty weird theories.

Black holes are predicted by the well tried and tested theory of General Relativity (a theory that has predicted many things) and observable evidence. They can even be explained by common sense pretty succinctly. There's basically 0 doubt about the existence of black holes.

Not to mention that you can't see a black hole, it's black. It emits no electromagnetic radiation. You can only see its effects.

But now Hawking is saying that Black hole maybe leading to another universe..( like a worm hole). If so, how does it look from the other universe?. If the info does get destroyed in the black hole does it go to the other side?. or just stay in the event horizon?.

He's still at it?.....
Is he going to bet on it again?.

In 1997, Stephen Hawking and Kip Thorne made a bet with John Preskill on the ultimate resolution of the apparent contradiction between Hawking radiation resulting in loss of information, and a requirement of quantum mechanics that information cannot be destroyed. Hawking and Thorne bet that information must be lost in a black hole; Preskill bet that it must not. The formal wager was: "When an initial pure quantum state undergoes gravitational collapse to form a black hole, the final state at the end of black hole evaporation will always be a pure quantum state". The stake was an encyclopaedia of the winner's choice, from which "information can be recovered at will".[6] Hawking conceded the bet in 2004, giving a baseball encyclopaedia to John Preskill. Thorne has not formally conceded.

The Thorne***8211;Hawking***8211;Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other.

Thorne and Hawking argued that since general relativity made it impossible for black holes to radiate, and lose information, the mass-energy and information carried by Hawking radiation must be "new", and must not originate from inside the black hole event horizon. Since this contradicted the idea under quantum mechanics of microcausality, quantum mechanics would need to be rewritten. Preskill argued the opposite, that since quantum mechanics suggests that the information emitted by a black hole relates to information that fell in at an earlier time, the view of black holes given by general relativity must be modified in some way. The winning side of the bet would receive an encyclopedia of their choice.[1]

In 2004, Hawking announced that he was conceding the bet, and that he now believed that black hole horizons should fluctuate and leak information, in doing so providing Preskill with a copy of Total Baseball, The Ultimate Baseball Encyclopedia.[2] Comparing the useless information obtainable from a black hole to "burning an encyclopedia", Hawking later joked, "I gave John an encyclopedia of baseball, but maybe I should just have given him the ashes."[3] Thorne, however, remained unconvinced of Hawking's proof and declined to contribute to the award.[4] As of 2008, Hawking's argument that he has solved the paradox has not yet been accepted by the community, and a consensus has not yet been reached that Hawking has provided a strong enough argument that this is in fact what happens.

Hawking had earlier speculated that the singularity at the centre of a black hole could form a bridge to a "baby universe", into which the lost information could pass; such theories have been very popular in science fiction. But according to Hawking's new idea, presented at the 17th International Conference on General Relativity and Gravitation, on 21 July 2004 in Dublin, black holes eventually transmit, in a garbled form, information about all matter they swallow:

My point in this is He's been wrong before and he could be wrong again!.
