>suggests that it has no tangible relation to physical phenomena. A lot of mathematics is that way, and there's nothing wrong with that. Sometimes mathematical concepts do find tangible physical phenomena that demonstrate them - but sometimes, centuries after they've been invented. Mathematics is often about what one can imagine. Our imagination can be inspired by the world around us, but it is not limited by it. It's not a red flag that some concepts don't have short explanations. Sometimes you really just have to know the full joke to get the punchline.
