I'm self-educated, and thinking about suing my instructor for malpractice. grin! Sounds to me like you have a really good instructor. Your post reminds me of a joke (sorry if you already heard).

An old man is walking in the street and talking to himself. His neighbor asks, "Why are you talking to yourself?" He answers, "I always enjoy speaking with an intelligent person."

LOL! I've got neighbors that talk to themselves, but that AIN'T the reason.

I love to nibble at the edges of physics, but I have too many interests to immerse myself in it. Besides, I not sure I could understand what Fairbank, et al. actually proved without a real instructor to explain it. My eyes cross when I start reading about fractional charges. I appreciate your input to this thread tonight. You hvae been most instructive.

BTW, has anyone actually spun up a large mass (in a vacuum) to even sub-relativistic velocity and measured the delta in gravity?

Einstein did a gedanken but materials technology wasn't there then. We have it now. It shouldn't actually be that expensive to try. (plus or minus a few million)
