Remember they are quite faint here, needing large telescopes, and there are still more on the limits of our telescope's power we won't see until the large space telescope is put up. If the ones we're seeing are uniformly distributed in space, rather than along the gallactic plane, because we can't see any beyond 100 or maybe 1000 light years, then surely we can't see even ones ten or a hundred times bigger in other galaxies that are millions of light years away. ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
