So Leonard Susskind publishes a paper on arXiv

# Dear Qubitzers, GR=QM

Which of course is what I have been saying all along. Of course Susskind’s paper is actually ‘of course’ not about QM emerging from GR, which is what I believe, and have good reason to follow up on.

Instead Susskind says:

Dear Qubitzers, GR=QM? Well why not? Some of us already accept ER=EPR [1], so why not follow it to its logical conclusion? It is said that general relativity and quantum mechanics are separate subjects that don’t fit together comfortably. There is a tension, even a contradiction between them—or so one often hears. I take exception to this view. I think that exactly the opposite is true. It may be too strong to say that gravity and quantum mechanics are exactly the same thing, but those of us who are paying attention, may already sense that the two are inseparable, and that neither makes sense without the other.

The ‘paper’ (perhaps letter is a better name), has made the rounds/ Not Even Wrong,

Instead of that happening, it seems that the field is moving ever forward in a post-modern direction I can’t follow. Tonight the arXiv has something new from Susskind about this, where he argues that one should go beyond “ER=EPR”, to “GR=QM”. While the 2013 paper had very few equations, this one has none at all, and is actually written in the form not of a scientific paper, but of a letter to fellow “Qubitzers”. On some sort of spectrum of precision of statements, with Bourbaki near one end, this paper is way at the other end.

While Woit’s nemesis Lubos Motl,

Susskind also says lots of his usual wrong statements resulting from a deep misunderstanding of quantum mechanics – e.g. that "quantum mechanics is the same as a classical simulation of it". A classical system, a simulation or otherwise, can never be equivalent to a quantum mechanical theory. The former really doesn't obey the uncertainty principle, allows objective facts; the latter requires an observer and is a framework to calculate probabilities of statements that are only meaningful relatively to a chosen observer's observations.

Sabine Hossenfelder put it visually on Twitter:

My take is about the same as these popular bloggers. Don’t really think much of it.

Except the title. QM can, I believe, emerge from Einstein’s General Relativity, in much the same way that Bush and Couder’s bouncing drops can display quantum behaviour.

My research gate page has more.

Its ridiculous that 11 dimensions and sparticles have hundreds of times more study than fundamental emergent phenomena. Emergence is the way to go forward. You don’t need a new force/particle/dimension/brane to make fundamentally new physics from what we already have in electromagnetism and general relativity.

See the search links on the side of this blog for some recent papers in these areas.

Linking the worlds of GR, QM, and Newton has already been done. Democritus’s smallest identicle particles, Newton’s explanation of light (an aether wave overtakes and directs light corpuscles), and the STOE model which considers the “space” of GR the same as the medium of Bohm Interpretation. The pilot waves are caused by particles such as photons. Diffraction experimental results (Afshar Experiment and Hodge Experiment) reject wave models of light. Then classical equations can give diffraction, QM entanglement, and QM eraser effects.
