Hm. That is a very interesting point. I'll get back to you after I take my GR course in a year or so :P. I don't think it should affect the trajectory but GR has proved me wrong before, so.

And apologies - illusion of transparency and all that, I knew it wasn't spectacular but I didn't know it was incomprehensible. I wasn't going to spend a quarter-hour making a really good drawing, either, before I had decent confirmation I was talking with someone who knew what they were talking about.

(And huh, you're on DKA? I should pay more attention to usernames.)
