In fact I've always tended to drop minus signs, forget to differentiate terms, lose factors of 2pi, etc., and I do appreciate people pointing these things out. Now that I've been 29 for twenty years, my error rate has increased. Maybe that's why full professors keep graduate students around. Anyway, my admitting these limitations got interpreted as me stating that I didn't understand the fundamentals of general relativity, and when I said one thing, I really meant some other, wrong, thing.

As far as I know, Chris had no formal education in theoretical physics, but she does know relativity as well as any degreed physicist. Anyway, to anyone that cares, Carl sent me an email explaining his problem with Chris.

Yes, she is a real pain in the butt, but that's because she is a self-taught expert, with no background in physics, and she really knows her stuff.

I will add a bunch of pull down menus to select initial conditions that demonstrate various facts about gravity, Newtonian and relativistic. For example, I will have a bunch of points separated by only a small amount. When they orbit close to a black hole they will string out, thereby demonstrating tidal forces (sort of). Later I will update it to rotating black holes, make it 3 dimensional, and will even be able to do Lense-Thirring demonstrations. I found the relativistic equations by writing proper time as an integral of the line element ds^2 over t. Then the calculus of variations gives three differential equations in x, y, and z with respect to t. That is, a = F/m like Newton. This is new work and an improvement over current methods of "post Newtonian" celestial mechanics. It is very simple, but I suppose I will write up a paper and submit it to arXiv. The usual textbook GR method is to use affine parameters. This ends up with 4 differential equations, one of which, d^2t/ds^2 is redundant. My calculation pissed off the local GR experts who "corrected" my work by showing how the usual 4 DEs can be obtained fom Christoffel symbols. Now they've arranged to have the thread locked, the punishment usually given to threads that discuss theories that blatantly violate relativity. I'm already laughing.

The calculation uses Painleve coordinates which are of interest to QFT because they are a single chart that covers the entire black hole. These coordinates have hope of treating gravity as a force on a flat Minkowski space, compatible with the rest of the standard model. Also, I will eventually read Foucalt's pendulum and The Name of the Rose. My reason for starting with The Island of the Day Before was because the local used book store had a new copy of it for $2.

But in this case there are so many things that can go wrong, that Nature (the bitch, not the magazine) will have a hard time picking a couple. Kea, you are most welcome as always. Hi Tripitaka, thank you. Just a note: the GM quote goes "Those are my principles...", not "my beliefs". I modified his sentence to fit the bill, but it works equally well. Island, the strong anthropic principle predicts that humanity is bound to fail in the search for the Higgs, because this Universe was made exactly for that purpose. Cheers to all, T.

What's the strong anthropic prediction?... HAHA!
