Thanks Q-reeus for this thread.
Thanks to Farsight for his quote of Einstein, as follows:
Thanks for your comments James R and rpenner.
I make reference to my earlier thread which was aimed at trying to distinguish the actual determinants of cosmological redshift, as opposed to just assuming it was all due to SR velocity of expansion and differential Doppler effects.
This is my thread of some months ago:
http://www.sciforums.com/threads/distinguishing-cosmological-expansion-frame-from-sr-frame.156053/
In my opinion it was effectively sabotaged, and discussion of the alternatives shut down before proper discussion on the actual OP alternatives got under way, by posters who were adamant in misconstruing the alternatives put by me, for consideration on their respective merits, as somehow preferring one or the other. I hope by now it will have become clear that I just posed the alternatives for consideration and discussion to eventually hone in on the actual cause and mechanism responsible rather than just assuming SR Doppler because no distinguishing possibilities between the two existed or were so far identified.
The reason I bring up my past thread is that if proper discussion was allowed to proceed then without all the prejudicial misconstruing, we may have all arrived at the answer to the question raised by Farsight's quote of Einstein above.
It appears that those who effectively shut down my earlier thread are now claiming that the GR considerations of spacetime condition is
not relevant?
Yet how can this be
IF there is no
SR or Doppler speed differential involved in the purely gravitational scenario where light is emitted/absorbed in gravitational well positions which differ and so create different frequency/wavelength photons as per the
clock rate applicable at those respective locations according to GR experimental evidence confirming such clock rate differentials exist due to gravity well position?
As far as I can ascertain, Farsight has raised a valid point in quoting Einstein in the context of clock rate and photon frequency emitting/absorbing processes which are determined by such clock rates at different gravity well radial positions.
It is now on those who disagree with Farsight to explain why in
my earlier thread the possible condition of spacetime during expansion was dismissed in preference for assuming SR/Doppler causes due to expansion speeds etc, but Einstein and GR clearly present the spacetime differences in different gravity well radial positions as being the determinant not any speed or SR considerations.
Maybe if my earlier thread and discussion had not been sabotaged and shut down so early by posters who didn't really understand what was being considered, then this question raised by Farsight and Einstein quote could already have been settled?
I can only conjecture what might have come of my thread if it had not been so carelessly mistreated and ignored by those very same posters who now cannot present any SR/Doppler arguments for emission/absorption frequency differences at different GR gravity well radial positions where spacetime condition differs between the two positions according to well proven scientific evidence from relevant GR-ONLY scenario clock rate experiments excluding SR/Doppler factors.
This post after long absence has been my overt expression of disappointment at the way my earlier thread and discussion was treated by those learned members who should have known better how to read that OP and how to discuss properly without prejudicial straw man and ego based dismissals out of hand like that was.
I am not going to participate further in this thread or indeed my above earlier thread, because I have come to realize very quickly that certain groups of posters here are more interested in politics and ego than in proper discussion based on objective merits of OPs. I have no objections to obvious pseudoscience etc being moved and ignored as appropriately; but I do have strong objections to the way my earlier thread and OP alternatives were treated by learned members who should have read properly before making misconstrued and straw man responses like they did and I was helpless against because it would have involved in never ending conflict and confusion brought by those who did not want proper discussion because they has already made up their minds and beliefs rather than discussing on merits/possibilities involved.
That is my opinion on the above issue raised by Farsight-Einstein GR quote; and my personal reaction to what happened to my earlier OP and thread which taught me not to pursue any really serious discussion at this site in future; but merely make occasional comments, if at all, if and when I bother to read here, which is now seldom.
Thanks again Q-reeus, Farsight, James R and rpenner for giving me something of interest to comment on today. I will come in again next week to see how this thread gets on in the question of gravitational redshift cause and effects on photon frequency/wavelength and associated issues. See you then.
