Physical objects cannot occupy the same space at the same time. — SophistiCat
They do at the center of a black hole, don't they? Time stops, so I don't know if "same time" means anything there. — frank
Even if that is true, we cannot put history aside. History of something is its property. Two things, even if the same size, color, weight, shape and in the same location, are not the same things if they have different history. — elucid
Fine. Two fields can occupy the same space. How's that? — frank
To simplify things for shmucks such as myself: I'd imagine that if they do occupy the same space at the same time, it would be analogous to temperature and pressure being two ways of viewing the same physical given. But not two separate physical givens. — javra
A temperature field is not the same thing as an electromagnetic field, though they occupy the same space. — frank
Temp and pressure relate by way of volume. They only track with a constant volume. — frank
Cool. What kind of object is a temperature field? — frank
I think you mean abstract object. A number is an abstract object. — frank
Is that what temperature fields are? — frank
It's considered by physicists to be a physical object. Do you disagree with them? — frank
A Grand Unified Theory (GUT) is a model in particle physics in which, at high energy, the three gauge interactions of the Standard Model that define the electromagnetic, weak, and strong interactions, or forces, are merged into a single force. Although this unified force has not been directly observed, the many GUT models theorize its existence. If unification of these three interactions is possible, it raises the possibility that there was a grand unification epoch in the very early universe in which these three fundamental interactions were not yet distinct.
Experiments have confirmed that at high energy, the electromagnetic interaction and weak interaction unify into a single electroweak interaction. GUT models predict that at even higher energy, the strong interaction and the electroweak interaction will unify into a single electronuclear interaction. This interaction is characterized by one larger gauge symmetry and thus several force carriers, but one unified coupling constant. Unifying gravity with the electronuclear interaction would provide a theory of everything (TOE) rather than a GUT. GUTs are often seen as an intermediate step towards a TOE.
