Generalizations on, It from Bit

I know there is an essay question going on and I thought it might quite the challenge indeed to wonder and construct from a layman standpoint some of the ideas that are emerging from the challenge.

The past century in fundamental physics has shown a steady progression away from thinking about physics, at its deepest level, as a description of material objects and their interactions, and towards physics as a description of the evolution of information about and in the physical world. Moreover, recent years have shown an explosion of interest at the nexus of physics and information, driven by the “information age” in which we live, and more importantly by developments in quantum information theory and computer science.

We must ask the question, though, is information truly fundamental or not? Can we realize John Wheeler’s dream, or is it unattainable? We ask: “It From Bit or Bit From It?”

Possible topics or sub-questions include, but are not limited to:

What IS information? What is its relation to “Reality”?

How does nature (the universe and the things therein) “store” and “process” information?

How does understanding information help us understand physics, and vice-versa?

 See: It From Bit or Bit From It?

So maybe as I go along it will contrive into something tangible, worth considering. If I show it’s production here and it eliminates any possibility of an entrance, then it”s nice that I will have learn something along the way.

Part 1

To my mind there must be, at the bottom of it all,
not an equation, but an utterly simple idea.
And to me that idea, when we finally discover it,
will be so compelling, so inevitable,
that we will say to one another,
“Oh, how beautiful !
How could it have been otherwise?”
From a personal notebook of Wheeler circa 1991

This symbol was used to demonstrate in a global sense that everything is derived from bits. Taken from a speech given by John Archibald Wheeler in 1999.  Also from, J. A. Wheeler: Journey into Gravity and Spacetime (Scientific American Library, Freeman, New York, 1990),  pg. 220

So the idea here while starting from a vague representation of something that could exist at of deeper region of reality is ever the question of where our perspective can go. So as if telling a story and reaching for some climax to be reached I ponder a approach. If one goes through the story it is to bring fastidiously a place in the future so as to see where John Archibald Wheeler took us now, in the form of his perspective on Information, Physics and Quantum.

So indeed I have open on a simplistic level so as to move this story into the forum of how one can might approach a description of the wold so as to say it’s foundation has been purposeful and leading. So I will move forward and present a phenomenological approach considered and go backward in time.

Quantum gravity theory is untested experimentally. Could it be tested with tabletop experiments? While the common feeling is pessimistic, a detailed inquiry shows it possible to sidestep the onerous requirement of localization of a probe on Planck length scale. I suggest a tabletop experiment which, given state of the art ultrahigh vacuum and cryogenic technology, could already be sensitive enough to detect Planck scale signals. The experiment combines a single photon’s degree of freedom with one of a macroscopic probe to test Wheeler’s conception of “quantum foam”, the assertion that on length scales of the order Planck’s, spacetime is no longer a smooth manifold. The scheme makes few assumptions beyond energy and momentum conservations, and is not based on a specific quantum gravity scheme See:Is a tabletop search for Planck scale signals feasible? by Jacob D. Bekenstein-(Submitted on 16 Nov 2012 (v1), last revised 13 Dec 2012 (this version, v2))

The question of any such emergence is then to consider that such examples held in context of the digital world of physics. This is to say it can be used to grossly examine levels to take us to the quest of examining what exists as a basis of reality. So too then,  as to what can be described as purposeful examination of the interior of the black hole.

Jacob D. Bekenstein

Such examinations then ask whether such approaches will divide perspective views in science into relations that adopt some discrete or continuum view of the basis of reality. This then forces such division as to a category we devise with respect to the sciences as theoretical examinations and it’s approach. So from this perspective we see where John Wheeler sought to seek such demonstration in which to raise the question of a basis of reality on such a discrete approach?

So such foundational methods are demonstrated then as to form from such developments in perspective. John Wheeler sought to seek a demonstration of the idea  of foundation as an end result by his students. To seek an explanation of the interior of the black hole as to demonstrate such a progeny in his students is to force this subject further along in history. So,  from this standpoint we go back in time.
