Some less and more wild notions about the quantum gravity enterprise

#1

Post by notFritzArgelander »


In a recent thread https://theskysearchers.com/viewtopic.php?t=25335 @Gmetric posted an interesting video on BHs and the information paradox which following on recent threads on the ER = EPR slogan

https://theskysearchers.com/viewtopic.php?t=25388 and

https://theskysearchers.com/viewtopic.php?t=25069

suggested some connections to me. This resulted in my changing my thinking about the ER = EPR slogan. Initially I was highly skeptical, but I am now persuaded that there might be more to it all. There followed a series of intuitions about other things that might be packaged together and I soon found myself with an ensemble of notions that might also be clues to facets of quantum gravity.

The top line inspired by EP = EPR is that the quantum gravity may be a realization of the parable of the blind men and the elephant.

https://en.wikipedia.org/wiki/Blind_men_and_an_elephant

So I decided to push that as far as I could. ;)
A king has the blind men of the capital brought to the palace, where an elephant is brought in and they are asked to describe it.
When the blind men had each felt a part of the elephant, the king went to each of them and said to each: "Well, blind man, have you seen the elephant? Tell me, what sort of thing is an elephant?"
The men assert the elephant is either like a pot (the blind man who felt the elephant's head), a winnowing basket (ear), a plowshare (tusk), a plow (trunk), a granary (body), a pillar (foot), a mortar(back), a pestle (tail) or a brush (tip of the tail).
The men cannot agree with one another and come to blows over the question of what it is like and their dispute delights the king.
Here is a laundry list of things that I think are like the reports of the blind men on their elephant experience. I’ll divide the views into sections. The first section of the list consists of items that are more or less “mainstream” and the second section consists of personal idiosyncrasies. After the list is a narrative that links the items.

1) String theory and quantum loop gravity are in some sense duals of each other
https://www.quantamagazine.org/string-t ... 0160112/

2) Causal set theory is another facet that is not incompatible them both

3) As a result of 1 & 2 ER = EPR and the BH information problem might resolve

4) Consider also conformal field theory (CFT) and scale invariant field theories (SIFT)

https://en.wikipedia.org/wiki/Conformal ... variance https://www.quantamagazine.org/symmetri ... 20220112/ https://www.quantamagazine.org/to-avoid ... 20140818/

5) AdS/CFT correspondence, rather than merely criticizabie as not the space in which we live, might admit novel topologies for the universe accommodating ER + EPR ideas more naturally than the space of the standard cosmology

https://en.wikipedia.org/wiki/AdS/CFT_correspondence

6) Bootstrapping time?

https://www.quantamagazine.org/the-orig ... d21d14a9ea

7) Consider quantum contextuality

https://www.quantamagazine.org/the-spoo ... wz4OrPp6m8

8) A fundamental set of particles is a self-consistent set so the bootstrap theory insight can be included. Can a bootstrap principle predict the constants of the standard model?

https://en.wikipedia.org/wiki/Bootstrap ... -20170223
https://www.quantamagazine.org/how-simp ... -20191209/

9) ECSK gravity might be a better choice than GR since there may be nore topological freedom with a metric that is less symmetric and less constrained.

10) Wheeler’s “It from bit” is as close to reality as can be achieved, Reality Itself is unknowable. We need only work at finding real laws governing phenomena. The Real Laws of the universe are not necessarily knowable.

11) Wheeler’s “one electron universe” may be compatible with the above
https://en.wikipedia.org/wiki/One-electron_universe

12) Zitterbewegung is a manifestation of 1 & 2 & 10 & 11? Link to causal sets? Standard model masses as diffusion coefficients?
https://en.wikipedia.org/wiki/Zitterbewegung

I'll add a post containing a narrative of how these might hang together in a later post here.

Initial impression, probably way wrong...

a sort of really complex 'dance' that determines what reality is?

Exactly so, if reality is understood as phenomenal reality and not as Reality-In-Itself. I'm writing up how this might all work together (at least in my vain imaginings).

You get it into comprehensible book form (maybe consult with a competent writer there) and I'll buy it.

That said, it seems to me like your approach might be...shaving the lines...between 'phenomenal reality,' 'reality-in-itself,' and some version of pantheism. Maybe. If one squints hard enough.

Sir! I strongly protest! I am as innocent as the driven snow! I make no pretense of thinking about anything more real than models of the phenomenally real! :)

Actually there may be some relevance of this old thread: https://theskysearchers.com/viewtopic.p ... les#p65394
