If you cannot understand it, then probably it doesn't matter for you, because you have no problem to solve. Most of the time, physicists are trying to invent a mathematical formula or construct to elegantly describe a physical process, to make an accurate prediction.
Just imagine, that we have a game, where we want to accurately predict next frames of a video. It's an interesting game on its own, because you need to understand deeply what happens on the video to be able to accurately predict behavior of all objects, animals, and persons in the video.
Such game requires a lot of skill, to accurately guess and predict, but most of the time it's not important for us, mere mortals. For example, we put a lot of effort into OpenGL, PBR, physic engines, etc. to make realistic games. Do you feel obligated to study all of that when you are interested in a realistic fly simulation? Do you feel obligated to study construction of AK when you like to play a 3D shooter?
If you really want to understand physics, then I suggest to perform experiments, or play with a physical simulation, or, even better, to implement your own physical simulation. Look, for example, at this beautiful simulation of black hole done in OpenGL shader:
