In other words, you can eliminate the need for a non-Doppler redshift mechanism if you can devise a way of accelerating starlike objects to substantial fractions of c (interactions with the magnetic field of an exploding galactic core?). At one time this was a respectable theory; I don't know its current status. One problem is that one should then see some blueshifted objects as well, although one can fend this off by claiming that we aren't looking at the right wavelengths to see the major emissions of a massively blueshifted object. How this explanation stands in the presence of increasing astronomy efforts in the UV and X-rays, I don't know. Any attempt to avoid the "cosmological" explanation of quasars also needs to bear in mind that things like the recent case of double images of a quasar being formed by gravitational lens effects of a distant galaxy DO put a lower bound on the distance of SOME quasars. ----------------------------------------------------------------- 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.
