- He's shown no such thing. What he HAS done is sorted through a lot of
- astronomical images involving quasars and found a few instances where the
- quasar and a relatively nearby galaxy are almost in line of sight, and in which
- there is some sort of nebulous material that happens to enclose both the galaxy
- and the quasar IN THE TWO-DIMENSIONAL PROJECTION.
-
- From this, he reached the conclusion you stated above, and decided that he
- needed time on some four-meter scopes to decide things. Of course, observing
- time on four-meter scopes is rather scarce, so the groups that schedule such
- time require that one demonstrate that your project is worth pursuing.
- Apparently Arp did not do that to the satisfaction of the groups that schedule
- time on such scopes. If I recall correctly, what they demanded was that, before
- being given time on the scopes, he do a statistical analysis to show that the
- stuff he's got photographs of can't be explained by chance.

-
- That's one explanation, and Arp hasn't, to the best of my knowledge, given any
- strong argument that rules out that possibility.
-
- >Does anyone know more about (the refutation of) Halton Arp's theories?
-
- As far as I know (and please note my sig), Arp hasn't made a persuasive enough
- argument for his claim to get any other scientists to take it seriously enough
- to refute it. Basically, a first cut at refutation would entail doing the
- survey of pictures of quasars, and the statistical analysis that Arp should
- have done himself. If Arp's not willing to do that, why should anybody do his
- work for him?
