Title: Has Stephen Hawking Been Wrong For The Last 30 Years?

With his cutting-edge research on black holes in the 1970s, Stephen Hawking emerged as a major player in the physics world. Then, with the 1988 publication of the bestseller, A Brief History of Time, Hawking achieved international celebrity status.

As this BBC presentation shows, Hawking’s fame might rest on weaker foundations than most could have imagined. Several important physicists, including Leonard Susskind here at Stanford (see our previous references to him), zeroed in on Hawking’s major contention that, when black holes disappear, they take along with them all information that ever existed inside them, which leads to the logical conclusion that there are clear limits to what scientists could ever know about black holes. After 20 years of debate, the Susskind camp seems to have won out, leaving Hawking’s legacy in question.

Called the Hawking paradox, he solved it himself demonstrating that no information was lost.

In July 2005, Stephen Hawking published a paper and announced a theory that quantum perturbations of the event horizon could allow information to escape from a black hole, which would resolve the information paradox. His argument assumes the unitarity of the AdS/CFT correspondence which implies that an AdS black hole that is dual to a thermal conformal field theory. When announcing his result, Hawking also conceded the 1997 bet, paying Preskill with a baseball encyclopedia "from which information can be retrieved at will". However, Thorne remains unconvinced of Hawking's proof and declined to contribute to the award.

I like Hawking. However, I think his resolution of the paradox is something of a cop out. In a TV documentary about the subject, he concludes at the end that information persists in parallel universes that do not have any black holes.

Ooh...kayy...

I'm open to the notion of parallel/alternate universes, but I still considered his answer a cop out. An alternate universe that even somewhat resembles our own would have physical laws that would inevitably include black holes.

There goes the neighborhood.

this says it all for me -

Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.

+++++++++++++++++++++++++++++++++++++++

We have to open our hearts to Him.

He's not going to do a dynamic entry into our lives.

It is our choice to make, or not.

Lod, I truly like your style ! Simple truths are obvious ... while long-winded diatribes are bullshit !
