Blackhole Information Paradox

What good is a universe without somebody around to look at it?
Robert Dicke

John Archibald Wheeler (born July 9, 1911) is an eminent American theoretical physicist. One of the later collaborators of Albert Einstein, he tried to achieve Einstein’s vision of a unified field theory. He is also known as the coiner of the popular name of the well known space phenomenon, the black hole.

There is always somebody who is the teacher and from them, their is a progeny. It would not be right not to mention John Archibald Wheeler. Or not to mention some of his students.

COSMIC SEARCH: How did you come up with the name “black hole”?

John Archibald Wheeler:It was an act of desperation, to force people to believe in it. It was in 1968, at the time of the discussion of whether pulsars were related to neutron stars or to these completely collapsed objects. I wanted a way of emphasizing that these objects were real. Thus, the name “black hole”.

The Russians used the term frozen star—their point of attention was how it looked from the outside, where the material moves much more slowly until it comes to a horizon.* (*Or critical distance. From inside this distance there is no escape.) But, from the point of view of someone who’s on the material itself, falling in, there’s nothing special about the horizon. He keeps on going in. There’s nothing frozen about what happens to him. So, I felt that that aspect of it needed more emphasis.

It is important to me to understand some of the history of the Blackhole, and the students who went on to develop the very ideas around them. To see how they interconnect at one time or another, to provide for the very insights from such gatherings.

Stephen Hawking’s says:

“Roger Penrose and I worked together on the large scale structure of space and time, including singularities and black holes. We pretty much agree on the classical theory of theory of relativity but disagreements began to emerge when we got into quantum gravity. We now have different approaches to the world, physical and mental. Basically, he is a Platonist believing that’s there’s a unique world of ideas that describes a unique physical reality. I on the other hand, am a positivist who believes that physical theories are just mathematical models we construct, and it is meaningless to ask if they correspond to reality; just whether they predict observations.”
( Chapter Six-The Large, the Small and the Human Mind-Roger Penrose-Cambridge University Press-1997)

See: Phil Warnell’s comment.

Black hole information paradox

Whereas Stephen Hawking and Kip Thorne firmly believe that information swallowed by a black hole is forever hidden from the outside universe, and can never be revealed even as the black hole evaporates and completely disappears,

And whereas John Preskill firmly believes that a mechanism for the information to be released by the evaporating black hole must and will be found in the correct theory of quantum gravity,

Therefore Preskill offers, and Hawking/Thorne accept, a wager that:

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 loser(s) will reward the winner(s) with an encyclopedia of the winner’s choice, from which information can be recovered at will.

The black hole Information Paradox results from the combination of quantum mechanics and general relativity. It suggests that physical information could “disappear” in a black hole. It is a contentious subject since it violates a commonly assumed tenet of science—that information cannot be destroyed. If it is true, then cause and effect become unrelated, and nothing science knows, not even our memories, can be trusted.

Before the Big Bang

Professor Sir Roger Penrose, OM, FRS (born 8 August 1931) Before the Big Bang

Three Different Views of Quantum Weirdness
(and What It Means)

A: According to the orthodox view of quantum mechanics, called the Copenhagen interpretation, a system (represented here by a child’s block) does not occupy a definite state or location until it is measured. Before then it is just a blur of overlapping possibilities.

B: The many worlds interpretation insists that the system occupies all its possible states but that every one of them exists in its own alternate universe. Each universe sees one state only, which is why we never observe the block in two states at once.

C: In Penrose’s interpretation, gravity holds our reality together. In each potential state, the block generates a separate gravitational field. Over time, the energy required to maintain these multiple fields causes the block to settle into one state only—the one that we observe.

See:If an Electron Can Be in Two Places at Once, Why Can’t You-by Tim Folger, Photograph by David Berry, Illustrations by Don Foley?

In Penrose’s interpretation, gravity holds our reality together. In each potential state, the block generates a separate gravitational field…..,” rings with a certain importance when one talks about what happens with the very nature of the blackhole. What happens to that information.

Phil Warnell:However, if the second is taken as truth and all is remembering, then what can the force of gravity do to a memory that is not in any, yet of all?

I tried to implement a method by which one could “gauge the significance of the emotive experience” as it may pertain to that “primitive part” of our nature. That we could see “remembering” had been assigned a “quantum reductionist state” within the confines of that methodology?

See:Quantum State reduction as a real phenomenon by Roger Penrose (Oxford)2 Sep 1999

“The block,” while holding different gravitational defined consciousness states, had to settle to a strong emotive consolidating force from that experience. You repeatedly relive the experience, while current information saids that the memory can change. See Ledoux.

    The Information triangleWhile I do not have the book that Phil has drawn the quote from, I thought it important that the image I seen resonate with what is written by Roger Penrose. Resonates with what is being exemplified by use of the image. I could be wrong, but it seems to me to be the basis of what I see not only in context of what Tegmark grasps onto, but Bee of Backreaction as well.This was the “intuitive tag” that I thought ignited something in your mind Phil. There is a reference for this for consideration that is fleeting right now. I’ll have to come back to it later. It’s when I seen you say, “I see now,” over at Backreaction.:) Yes, quite vague indeed.Penrose saids,I I think that Fig. 34.1 best expresses my position on this question, where each of three worlds, Platonic-mathematical, physical and mental-has it’s own kind of reality, and where each is (deeply and mysteriously) found in one that precedes it ( the worlds take cyclicly). I like to think that, in a sense the Platonic world may be the most primitive of the three, since mathematics is a kind of necessity, virtually conjuring its very existence through logic alone. Be that as it may, there is a further mystery, or paradox, of the cyclic aspect of these worlds , where each seems to be able to encompass the succeeding one in its entirety, while itself seeming to depend only upon a small part of its predecessor.”(Page 1028-The Road to Reality- Roger Penrose- Borzoi Book, Alfred A. Knoff- 2004)Click on paragraph. It was important that where the language ends, that the image take over. This would have been the “universal language” that discounts all languages, including the mathematics, yet, mathematics would had been closer to the source, while the image would be, “the source.”In this sense then I hope I had capture the awareness of what trigger “recognition” in another’s mind.I like to think that, in a sense the Platonic world may be the most primitive of the three… holds some what of a fascination, since I think this aspect is not primitive at all. Primitive in the sense that time is measured by Plato’s appearance, but not by some of the nature of thoughts that could have been spoken in context of how the world is being demonstrated today.Two points came to mind here when I thought about Coxeter and Susskind’s image of the vibrating rubber band. “The image” was the culmination of serious work.Dirac’s very nature. He was gifted in this way as was some of the ones I have highlighted in terms of their visionary skills.Least I forget Feynman too, had this skill, while his diagrams are a testament to the distillation process he took his mind through.You see now?:)

    Hi Plato,A very nice piece that captures much of how I think. I must remind however, that I am merely conveying as an echo the thoughts of others and that I make no claim they are my own. They do however serve to give some place to stand as I struggle to see. The likelihood that I might ever do so is practically zero; what I truly hope for is that others who have also discovered this path, do have the power of mind required, so that I might discover if it leads to a place that holds only what I can imagine. I will however from time to time share more of my thoughts with you, as I find ways to make them clear.Best,Phil

    Phil:what I truly hope for is that others who have also discovered this path, do have the power of mind required, so that I might discover if it leads to a place that holds only what I can imagineWhen you had said about, “contribution of service for others,” this is what it is about for me. If we can awaken something in any person, this may provide for new roads to understanding, then for me, all one can do is just lay it out there. I do not ever “own it.” The pool from which we draw(all probabilities), is not mine and belongs to everyone.This is something I learnt about service to others. Sometimes it can be a “quiet thing” that can be done that “leaders can lead” from anonymity. You can be a factory worker, a waitress, a banker and it is within the group that you work, that you provide incentive for growth through “contribution of thoughts about anything” to provide for a betterment of this/that system. “Any contribution” is to be provided for through such incentives. People will tend to dig deep within themselves, working within such a “nurturing environment.”This is what I felt about the “PI Institute.”This is a powerful experience in my journey to know that what one can give of self, “we have to let go” so that service can move on and ignite newer realities.I am ill equipped in a lot of areas yet, I persevere to live according to the tenets of science’s requirements. You are providing this service for me, so I look forward to your sharing “what lies in waiting” in those imaginations.This does not mean any of us should disregard their long road to discovery of self, “who is it” in the face of other people that work in science. There will most definitely be corrections. This is what learning and acquiring knowledge is about.
