    Astronomy professors rave about how nutty it is that the only way we can measure it is through our understanding Newtonian mechanics alongside the implications.

Special Relativity, not Newton, but otherwise spot on. History is full of these "I have no idea on the why or how, but here is a bunch of math to describe and make predictions" when it comes to natural phenomena. Hell, speaking of Gravity, what is it? I mean Why is there Gravity? We understand DNA and evolution magnitudes more in depth than we do one of the four universal forces of the universe!

This is obviously just one of the more mainstream theories, but I found a very nice lecture series that tries to explain/ground concepts of loop quantum gravity. No maths but also no stock animations of vibrating strings. ;)

Hitting this up after Passover tonight. Fucking love TierZoo, in case I haven't said that enough.

I think you have just introduced me to my new favorite website. Thanks!

My pleasure! I'd also urge you to check out either of Brian Greene's Special Relativity courses they are hosting (there's one purely conceptual and one formal), even you if are already familiar with the material. It's hands down among the best lecture series in physics I watched and I strived to emulate some of his style in my own outreach work.

Everything they have looks like something I will enjoy, but I will make sure to put those high up in the queue!

Ahh, expecting to learn more about this next semester, but the survey course spoke related it all back to conservation of angular momentum to explain the confusion around why the galaxies' rotations don't add up.

Gravity is a myth and we live on a flat disc accelerating upward. Check and mate

One time one of my coworkers was just staring off into space. I asked them if they were okay and they just kept on staring, and said "I know it's a meme and all, but seriously, how do magnets work?"
