I'm not sure what this question even means. In actual experiments, there is no such thing as "quantum interference pattern" vs...

But this is a special case, and you can't base a general count of "number of fields" on special cases. The ##B## field doesn't cease to...

No, it doesn't. The fact that the field is generated by the sources does not mean it incorporates the sources. The field and the sources...

Yes, it is not trivial. :wink: As in, yes, we have no bananas: https://en.wikipedia.org/wiki/Yes!_We_Have_No_Bananas

Yes, it is. Hobson did say "at least" 25 fields.

Up, down, strange, charm, top, bottom. Yes, that counting leaves out the quarks' color charge. But note that, for example, when we say...

Yes, I see that from the paper, thanks for the reference. Key things to keep in mind: the coordinates ##U## and ##V## are null. The...

6 leptons, 6 quarks, 12 gauge bosons, and the Higgs in the Standard Model. Of course this counting leaves out a lot of things. Hobson...

Do you mean this metric? If not, can you give a reference?

Not in the case where photons escape to infinity. In such a case, this... ...or its quantum analogus, is simply wrong. Photon that...

Technically, yes, this is possible. My understanding is that it's considered extremely unlikely, because whatever mechanism makes the...

Ok, fair enough.

No, they don't: Please don't post contradictory statements. Also, nonzero neutrino masses do not "suggest" that they do not travel at...

Classically, fhe field equations for light and gravity are similar, yes; both of them have the basic form of a differential equation...

That depends. It seems like your question is not specifically about any quantum aspects of light or gravity, but just about this: The...
