Previous Next Up Topic Cosmology / Alternative Cosmology / Lerner and the Tolman test (1275 hits)

Hilton has another newsletter out, this one all about Lerner et al's paper on the Tolman test and a static universe (of course).

I haven't seen the refereed paper, but I was intrigued to see in the preprint that they took on Lubin and Sandage 2001, the "gold standard" of proving universe expansion via Tolman test:

Lerner et al. preprint said:

The nonexpanding scenario was ruled out at the 10 sigma confidence level. These very same data are also re-discussed by Sandage[5], reaching similar conclusions.

These conclusions are not supported by the data for two main reasons. The first one is that, for the static scenario, Lubin and Sandage set the distance to d = (c/H0)ln(1 + z), which is valid only for the Einstein-de Sitter static case. This is not the cosmology we are testing here, where the Hubble relation is hypothesized to be d= cz/H0 at all redshift.


There's also an interesting note that similar luminosity corresponds with similar size in the 'static' case, but extrapolations have to be made in the expanding case; that's part of the luminosity 'evolution'.

Interesting to see someone do a modern take on Edwin Hubble's own objections :)
