That means the Seti hunt may need >to focus its attentions near hot, young stars or even near the >centres of galaxies." <snip> A late realization for Shostak: Isaac Asimov calculated - "It is nine times to eighty one times more likely that intelligence has arisen earlier in the central region of our galaxy" - basically because the class II stars of the central region are composed of older, recycled matter necessary for organic life. To confirm that, Hyron Spinrad found the metal content of stars - which indicates age of star generation - increases towards galactic centers. See 'Supermetallicity in nearby Galaxies' 1970 QrtlyJrnl of Royal Astronomical Society. Nb. 'Metal' to astronomers is anything heavier than hydrogen and helium - i.e stuff that has been manufactured inside stars. Possible reasons for that long delay by SETI? Maybe try UFO Updates posts on "SETI's real objectives?" www.ufoupdateslist.com/2008/may/m01-002.shtml and www.ufoupdateslist.com/2008/may/m06-001.shtml Cheers, Ray D Listen to 'Strange Days...
