Autzoo.1466 net.space utcsrgv!utzoo!henry Thu Mar 4 19:50:33 1982 quasar redshifts The Doppler-but-not-distant explanation of quasars WAS taken seriously at one point, because it is possible to explain the absence of blueshifts, small redshifts, etc. if the quasars are high-velocity objects expelled by the core of our own galaxy. This gives them a strong reason to all be pointing away from us: we are part of the structure that launched them. This does assume that they were launched in a particular epoch some time ago and are no longer being launched (or that some clever aspect of the launch process or the quasars themselves keeps us from seeing more recent launches). Maybe the quasars are trying to tell us something: perhaps expulsion of quasars is the first sign of an exploding galactic core... Of course, this theory does not sit well with several things found more recently. There are an awful LOT of the damn things. There is no other sign of the spectacular event that expelled them. Some of the quasars found after serious searches started have redshifts indicating velocities of 0.9c+, which is hard to explain. We don't seem them around other galaxies, and assuming that ours is unique is rather ad hoc. And finally, this theory cannot explain why some otherwise-typical-looking quasars definitely ARE far away.
