I'm not a mathematician or a physicist but interested in quantum mechanics/gravity/relativity. I'm trying to understand some ideas that are presented for laymen, and a lot of them talk about different fields. So I'm trying to understand it this concept a little better as I can't seem to visualize what it actually is.

First off the way I think about it now is what my Calc3 taught me like as in a vector field. Every point in space having some vector associated with it, so with some operations you can find out things like slope at points and find a direction. But every field that I can think about has some kind center of origin or position from which these fields radiate. Like a gravitation field would be emanating from the magnet, gravitational field emanating from the planet etc. But why do some things like higgs fields and gravitational are sometimes described as being everywhere.

Like in the book book Covalent Loop Quantum Gravity, by Carlo Rovelli, one of the things he says is that gravitational field is the same thing as space-time in general relativity. So the gravitation field must be present everywhere that space-time is present?

  I also read that particles in fields are just excitations of the field itself. So does that mean there is one single field and that all the other particles like all the bosons and all the fermions, just excitations of that field at different energies? Or are there separate fields that are just interacting with one another?

I'm not a mathematician or a physicist but interested in quantum mechanics/gravity/relativity. I'm trying to understand some ideas that are presented for laymen, and a lot of them talk about different fields. I understand what a field is and how to work with it, like finding a slope, direction of maximum increase etc. What I'm unsure of is why something like a higgs field is considered to be everywhere while a magnetic field or gravitational field seem to be generated by an object and are local. So my question is why do some fields have a distance limit and others can act at arbitrary distances and seem to be at every point in space? If possible I would like a technical answer first and then maybe some explanation. Thanks for answering.
