Why are you so surprised? We understand how gravity works to an incredible degree of precision, and anyone with a physics degree is able to explain it. You seem to have some misconceptions around physics. If you go through the formal training that we go through (i.e. spend years thinking about physics problems, papers and textbooks) you should understand that mathematics is a tool, and that physics is our best attempt at building mathematical objects that behave like the real world. What I mean by this is that we’re well aware that our theories are not perfect, and we can point to what doesn’t work (within our respective fields) quite well. At the same time, we’re aware of certain “features” of reality that cannot possibly be otherwise. Thermodynamics or special relativity are simple examples of this. Their validity is not in question, just as our existence in the first place is not in question (if you want to argue about philosophy go ahead, but that has nothing to do with the point I’m making). Therefore, even though we don’t have a perfect theory of physics, we can say that we understand certain stuff quite well. And vague statements about life and “new ideas” don’t help us advance our understanding. P.S. my view of the common “nobody understands quantum mechanics” saying is that only people who are too attached to classical reality can hold that opinion. The great founders of QM grew up without it, so are excused in thinking that QM is unintuitive. But for the most part the uneasy feeling about QM disappears when you let go of classical assumptions for good.
