Paul, I don't have a discussion group. I have a one-pager that I send out to people ( journalists, scientists, anyone ) from time to time and sometimes they respond. I find the addresses on the internet. Maybe I would type in Google Search: Faculty - Astronomy - South Africa and then get a list that way. If I send out 25 one-pagers I may get one response. Then if it's good I'll post it. It promotes Geocentism and I learn this way. Bernie Paul Deema <paul_deema@xxxxxxxxxxx> wrote: Bernie B Thanks for keeping us informed. I had a private bet that this would be his next question - Question: So it's the ether that provides a head-wind according to your theory. Another question, then: Do you agree that the surface layers of Jupiter are either liquid or gaseous? i.e. we can't see any hard ( e.g. rocky ) surface of Jupiter. RT Well you avoided that adroitly! Can anyone join your discussion group? I'd like to meet this Dr. Regner Department of Physics and Astronomy, even if just briefly.
