Gravitational Ramblings I was never really interested in physics, preferring instead the more pure branches of mathematics. Given that, much of what I'll say in this little discussion is probably already out there or just total nonsense, still just in case it isn't, I figured I just write it down. You never know, it's a strange world. I was watching a newly published lecture series with the eminent Richard Feynman. He said a couple of things that I had already learned about gravity, but I found fascinating anyways. The first was that Copernicus found that the planets traveled in a ellipse, with the sun being in the focal point. Quite well, known, but the relevance of the sun's position never really dawned on me before. Another thing he talked about was the measurements for a system far away, but the star's position wasn't at the focal point in the ellipse, he pointed out that this was because we were viewing the system from an angle. The final bit that I found i...
