That and I can pretend I'm crushing your head between my fingers.
Arp has shown galaxies and quasars which are positively connected together and are part and parcel of the same thing, and the quasars have the characteristic high redshift and the galaxies do not.
Not that I'm defending a dead horse, but I think Narlikar proposed that the H_alpha forest was ejecta from the same jet that ejected the quasar. I don't know that anyone has bothered to seriously examine the claims, as the whole theory is pretty much dead at this point anyway, for other reasons.
