<DIV><FONT size=2 face=Arial><SPAN class=218491718-07032010>There's a good
article at Science News about a subject that has puzzled me for decades, how it
is that matter around a black hole sheds enough angular momentum to eventually
fall in:</SPAN></FONT></DIV>

accretion disks of nearby stars, rather than collisions with other

be a big player in this phenom. Where's Amara these days? She would
