This is a Tom kind of question and he is the physicist, I'm just an engineer. You are aware of his traveling and the illness of his grandson at present so for the moment he may not get around to answering this. But as I have said before, when I don't have an answer, I sometimes wake up with one. In this case, and just going on the simplistic explanation in WikiPedia where I stopped to check my memory of the facts:
Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons. Neutrinos are affected only by the weak sub-atomic force of much shorter range than electromagnetism, and are therefore able to pass through great distances within matter without being affected by it. Neutrinos also interact gravitationally with other particles.
What I get from this and what little I remembered from before is that neutrinos interact the least with matter as they pass through.
Tom described the speed of light as resulting from the refresh rate of the 'screen pixels' in effect of the PMR simulation. Tom speaks metaphorically, and humorously, of the refresh rate of the screen pixels while what he is actually referring to is the amount of calculation required to deal with (do the calculations related to) a photon within that pixel (VR node point). If a neutrino interacts less strongly than any other form of "matter", then it takes less calculation to determine whether it interacts and to portray it as it moves from one 'screen pixel'/VR node to another "at least in some circumstances" as they said about it possibly and sometimes traveling faster than the speed of light, based on this new and as yet unconfirmed results. To me anyway this sounds like the reason that a neutrino can possibly move faster than a photon. Since the neutrino like a photon is not physical but a calculated thing in this VR, then it would seem like the amount of calculation required for its representation would be significant in terms of its ability to be represented as moving from one 'pixel' of the VR to another 'pixel'. Occurring in the lowest/smallest fractal level of the VR, it doesn't even have to be calculated except as lost in the probability of higher fractal levels when no one is 'looking' with appropriate detector equipment.
I would say that this new physics result is actually entirely in agreement with MBT
. Tom just never having had a reason to mention it before since no one
believed it possible for anything to move faster than a photon previous to this new research result. And they aren't even sure yet and are asking for others to reproduce their work.
This at least is my answer, whether and until Tom agrees when he is available to comment. After further thought and seeing further reactions by physicists, I think that this is actually a confirmation of the Virtual Reality, computed non physical, nature of PMR. It links the special behavior of neutrinos in these circumstances, if confirmed, to the computational requirements for their display within the simulation compared to the computational requirements for the simulation of photons. Of course, we don't know the details of those requirements, but that a particle that interacts so minimally with other matter would be less difficult to calculate versus photons which interact relatively readily seems like a reasonable assumption.
