Someone a while ago when all this was still in net.space, mentioned that some basic experiment upon which general relativity was validated had proven to be incorrect. I asked my physics student friend but, although he knew all about monopoles and some other things that had been under discussion, he hadn't heard of this. Could someone enlighten me? Ralph.

Doug, I'm still really confused. However, I don't want to clutter the Physics mailing list with this stuff if everyone else understands it. I guess the best bet is for us to continue this discussion on the mailing list until someone asks us to stop. Sound fair? Anyway, Hubble constant stuff aside...I don't understand this locality principle. I know a little bit about special relativity, but I don't recall anything about locality. What determines what is "local" & what is not? In particular, I'd like to know a little more about extrapolation away from the local environment. Help. --Hook [By the way: can you suggest some good books covering this stuff?]

From: Doug Gwyn VLD/VMB <gwyn@brl-vld> Your numbers look reasonably close at first glance. Of course, time dilation is what explains the whole phenomenon. I didn't assume total mass->energy conversion because I don't know how to do this. I do know how to build a chemical, ion, or other "conventional" rocket.
