If you intend to address challenges to the ATM ideas presented, as presented, concerning the (Hubble) scale of the universe and the universality of the Arp-Narlikar VMH, please say so explicitly.

However some galaxies have been demonstrated to have peculiar internal redshifts but of quite small magnitude compared to quasars.
This, it seems, is circular logic ... please clarify.

Specifically, please show that "some galaxies have been demonstrated to have peculiar internal redshifts" using observational and experimental techniques that have been rigorously shown to be fully consistent with the VMH.

Please also explain what the distance scale of the 'quasar' universe is, using observational and experimental techniques that have been rigorously shown to be fully consistent with the VMH.
Quote:
Generally, Narlikar has demonstrated that for VMH many things scale on (1+z) in the same way as they do for GR, i.e as 1st, 2nd or 3rd power.
Reference please.
Quote:
Actually for normal galaxies, the alternatives both depend on the same ladder steps to derive a real distance unrelated to redshift (otherwise you could not do a distance versus redshift scatter diagram). [snip]
Please provide a definition of "normal galaxies".

Please show that "the alternatives [upon which the ATM ideas presented in this thread depend] depend on the same ladder steps to derive a real distance unrelated to redshift" using observational and experimental techniques that have been rigorously shown to be fully consistent with the VMH, WSM, LSG, and LET.

I am pretty confident that the Hubble constant is now quite accurate as I can compare geological cycle periods to galaxy super-cluster distance spacings (the 128 Mpc that we discussed in the Redshift periodicity thread) and get a match.
I do not know if anyone is questioning, or has questioned, your confidence - certainly not me.

However, the explicit purpose of this ATM section of BAUT is to challenge and question ATM ideas, as presented.

In this thread you have presented an ATM idea that seems to depend - inextricably - upon several other ATM ideas, including WSM, LET, LSG, and the VMH. These ATM ideas seem to require a re-write of large parts of the standard physics that is incorporated in the estimation of distances beyond a kpc or so.

Logically, then, a potential weakness in the ATM ideas presented here is the relationship between distance estimates based on standard physics with estimates based on replacing key parts of standard physics with WSM, LET, VMH, and so on. In this set of related posts, I am asking about the extent to which those differences have been investigated and found to be unimportant.
Quote:
That match allows the Hubble constant to be immediately calculated to better than 1% accuracy and potentially to better than 0.1%. The present value I get is only about 0.3% different to the latest value that I saw.
Unless a rigorous demonstration that distance estimates are the same (to within a few percent, perhaps) - using the ATM ideas of WSM, LET, VMH, etc vs using standard physics - it seems all you have is an interesting coincidence ... and that is assuming that "the 128 Mpc" and "geological cycle periods" stand up to appropriate scrutiny (for avoidance of doubt, the very mild challenges these were subject to in earlier ATM threads is nothing compared with what they would be faced with if presented for publication in a relevant, peer-reviewed journal).
Quote:
When you do fundamental physics and cosmology in a more fundamental way, many more of these things appear as cross-checks. It also helps to use equivalent units such as years and light years to see the fit rather than seconds and Mpc/h which is the daftest unit ever.
Indeed.

However, when so many ATM ideas are proposed, it is all but impossible to challenge them effectively, especially when there are so many, potentially fatal, logical inconsistencies and errors to ferret out.
