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...

But that just underscores the point that no such thing happens with us humans and the measurements we make under ordinary conditions...

Yes, but "thoroughly erased" is one thing when it's just a qubit--it's quite another when it's, say, Schrodinger's Cat, containing...

That's only correct for a free particle, i.e., zero potential. That's not the case in your example; you have a potential confining the...

That's true. I haven't computed the actual deltas from the energy eigenstates the OP is using, but of course that could be done to see...

Yes, it assumes that the only source of uncertainty is that inherent in the quantum wave function. That's the argument I understood the...

You can't argue anything from an uncertainty relation where one of the factors is zero. That breaks the math.

And this invalidates the rest of your reasoning regarding ##\Delta p## being infinite. The correct conclusion from ##\langle H \rangle =...

No. The geodesic is a worldline. The 4-momentum is a 4-vector ##k^\mu## that is tangent to that worldline. And... No, this is not...

Since we are talking about relativity, the term "photon" is out of place; that's a quantum term. A better term might be "light pulse" or...
