> has a nice little introduction and the math in the overview isn’t too scary. Is it possible for a regular person(regular meaning not a researcher i guess, someone with unrelated day job) to understand the math and this kind of stuff at a deeper level?

I just read a book that gave a high level overview of some astronomy and physics topics like this one, but im unsure how to get a deeper understanding or if its even possible.
