Doesn't this paper support Penrose's OR theory?

Universal decoherence due to gravitational time dilation

Now Penrose being a very smart guy having realized that he has taken a realist standpoint on Quantum Mechanics very well knows that he has to incorporate some element of non-locality in his Twistor theory to account for Bell correlations.
Towards an Objective Physics of Bell Non-Locality: Palatial Twistor Theory by Roger Penrose

Is Twistor theory becoming an another example of Bohmian Mechanics?

Hi bremsstrahlung

I copy my email to Caslav Brukner, and his response, in regards to this experiment (17 June 2015):

Hi Caslav

This morning I saw on physorg.com an article about a Nature article which you are a co-author of: “Universal decoherence due to gravitational time dilation”.

I have a question:

When I see the word decoherence, I immediately think that quantum effects are suppressed, but don’t disappear (interference is harder to see, but if you take the system + environment it is in principle in a pure (superposition) state).

Is this the same with the coupling of the quantum system and the external environment (in this case classical general relativity time dilation); that is even though it the quantum system (either micro or macro) is coupled with this environment, the quantum effects are suppressed but in principle still exist?

Many thanks for any clarity you are able to offer.

Best regards
Stevie

His response:
Hi Stevie,

Yes, you are right, the quantum effects are suppressed but in principle still existent.

All the best,
Caslav

If I am not wrong that's exactly what Penrose is arguing that Gravity suppresses quantum superpositions.

In Einstein's theory, any object that has mass causes a warp in the structure of space and time around it. This warping produces the effect we experience as gravity. Penrose points out that tiny objects, such as dust specks, atoms and electrons, produce space-time warps as well. Ignoring these warps is where most physicists go awry. If a dust speck is in two locations at the same time, each one should create its own distortions in space-time, yielding two superposed gravitational fields. According to Penrose's theory, it takes energy to sustain these dual fields. The stability of a system depends on the amount of energy involved: the higher the energy required to sustain a system, the less stable it is. Over time, an unstable system tends to settle back to its simplest, lowest-energy state: in this case, one object in one location producing one gravitational field. If Penrose is right, gravity yanks objects back into a single location, without any need to invoke observers or parallel universes

As I understand Penrose's theory, it is gravity that causes wave function collapse. Being suppressed, superposition's are much harder to see. But if the system is in one state or the other, that isn't a suppressed superposition.
 
We often see discussions about what QM and QFT mean, but hardly anything on just how fundamental they are to much of physics. To rectify that, see the following; https://www.cambridge.org/engage/api-gateway/coe/assets/orp/resource/item/66a6a6005101a2ffa86cdd48/original/a-derivation-of-maxwell-s-equations-from-first-principles.pdf 'Somewhat magically, if one then applies local gauge invariance to the Dirac Lagrangian, a field appears, and from this field it is possible to derive Maxwell’s...
I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...
