     The jets eject the objects?  That's not the model I was referring to.
Supernova explosions eject the objects, and the jets are the residue
("wakes") in the paths of the ejections.

     I understand there is a full literature interpreting plasma jets in
standard models.  We are here considering a different model.  If this
supernova ejection idea has been "contradicted" in the literature, I have yet
to hear of it.

     Don't you specialize?  And don't most astronomers?  How can one or a
handful of astronomers proposing a new model be expected to come to grips
with even a reasonable fraction of the data that's in a single issue of the
ApJ?  New models have to start somewhere, and the gross tests come first.
Then if the results merit it, many more astronomers will test the model in
their own areas of specialization.

     A neat theory, but where are the specifics?  I can't recall offhand any
important facts in this area which went away in newer samples.  Quite the
opposite.  For example, on page 128 of the current (August) issue of Sky &
Telescope, right next to the supernova picture I referenced in another post,
is an article about a completely new, independent sample of accurate
redshifts which *confirm* Tifft's quantized redshift claims.  Whatever will
the standard model do with quantized redshifts, let alone time-variable
redshifts, as Tifft's latest results indicate?  -|Tom|-
