So in analogy to Einstein's general relativity which states that the curvature of space-time causes different bodies to act on each other through distance, how does electromagnetic force act through space? I don't think this can be explained in any way by the curvature of space-time, so what is it? I tried to search for an answer for this, and came across Theodor Kaluza's hypothetical fifth dimension applied to general relativity which can explain Maxwell's equations. I'm actually surprised by how little information I could obtain on the subject, since nobody seems to ask the question how does the electromagnetic force work, the same way people used to believe Newton's gravity is all there is. Or am I missing something that's out there, or is the subject too deep to be solved right now and need another 100 year until a great mind very much like Einstein's could come up with a revolutionary idea that will reshape our thinking about just everything?
