I think General Relativity gives us a better fundamental
understanding of what gravity is than we have for understanding what
electromagnetism is, all Einstein starts with is the existence of
movement, that is spacetime, and mass. Electromagnetism needs all that
too but also needs to assume the existence of something called
"electrical charge".

Science can tell us how things work, but as for why...... logically
the chain of why questions either goes on forever or it doesn't and
ends in a brute fact, after that there is no why, that's just the way
things are.

The sciences do not try to explain, they hardly even try to interpret,
they mainly make models. By a model is meant a mathematical construct
which, with the addition of certain verbal interpretations, describes
observed phenomena. The justification of such a mathematical construct
is solely and precisely that it is expected to work.
