In reply to Michel Jullian's message of Sun, 12 Oct 2008 00:34:39 +0200: Hi,
I haven't actually worked it out, but I don't even think that the gravitational field of a massive disc would be perpendicular to the disk, but probably directed more toward the center, and I suspect exactly at the center. >The gravitational field of the Black Hole itself is indeed radial, but >that of the whole system can be essentially perpendicular to the disk >if the accretion disk's mass is orders of magnitude higher than that >of the Black Hole's, which was my (possibly ludicrous) hypothesis. >There may be other problems with my simplistic suggestion, such as the >fact that it would imply a broader than observed spectrum of >velocities in the jet as pointed out by Horace (whose theory BTW I >can't comment on, having not studied it in any detail for lack of time >and skill) > >Michel [snip] Regards, Robin van Spaandonk <[EMAIL PROTECTED]>
