Higgs Field & GR: Are They Related or Not?

Since these two pillars of science have mass as a common core, are they related, essentially the same or not?

What do you mean by that?

Moderator's note: Thread title edited.

I don't know what you mean by that either, but I am pretty sure the answer is "no".

No they are not the same

It's clear what the OP meant; "Higgs field creates mass" and "mass creates gravity", so there could be a relation between Higgs and gravity. Of course, both claims in quotation marks originate from oversimplified and misleading explanations in pop-sci literature. Neither claim is really true, and there is no relation.

Maybe it seems that way to you, but the person who should be clarifying and explaining what the OP meant is the OP. @Dennis Plews please clarify what you meant, as has already been requested. Otherwise this thread will be deleted.

To use a famous quote: “Matter tells spacetime how to curve and spacetime tells matter how to move.” Here I am converting Prof Wheeler’s “matter” to what I consider to be a fair substitute, mass. Mass is now understood to be field excitations that have a positive coupling constant with the Higgs field and thus acquire the property know as mass. Hence it seems fair to inquire of experts if such Higgs couplings are causally related to GR.

Ok so far. But:

This is not correct. What "matter" actually means, when you unpack what GR actually says, is "stress-energy". Rest mass is only part of stress-energy, and things that have zero rest mass, like EM radiation, still have stress-energy and are still a source of spacetime curvature (and of course also still get told by spacetime how to move).

This is garbled. The Higgs mechanism is only one possible way that a quantum field can have mass. But in any case, "mass" in this case means "rest mass" (or invariant mass, which is a better term), and, as above, that is not the same thing as stress-energy.

And the answer is no. See above and previous responses.

Of course they are not the same. The question is whether they’re connected via their common core of mass. Has anyone examined this commonality to see if they are connected? The first thing that comes to my mind as a possible nexus is the stress energy tensor

OK, it appears that @Demystifier did indeed understand your question properly when he answered it in post #6 above. I don’t think we can much improve on his answer there.

See my post #9, which already addressed this (wrong) "possible nexus".
