Whenever I ask someone what an electromagnetic field is exactly, they say that science does how questions, not why questions (which doesn't really make sense in this context, maybe i worded my question differently). We say that there are four fundamental forces that create the universe we live in, and that those forces are fundamental to the universe... end of story. There is no point in asking what a force field actually is. I feel like this is sorta like that guy who said at the turn of the century that everything that can be invented has been invented. I mean we already kind of have an explanation for gravity, bent space-time and all that. So is it that we kind of have an idea what, say, an electromagnetic force field actually is but it's too complicated to explain to the masses?
