One of the subjects is answering the very questions you ask. Stay tuned. -|Tom|-

<br />New poster/amateur scientist here. Pardon if this has been covered, but: What degree of compatibility does or doesn't obtain between any of the four principal alternatives to the BB (Quasi-Steady-State, Plasma Cosmology, MetaModel, Variable-Mass Cosmology)? Is a "grand unified alternative" among any of these possible to synthesize? Thanks.

There are lot of people who think that the largest part of the redshifts comes from light-matter interactions.
The most interesting observations are:
- The periodicities in the "Lyman forests of the quasars" which may be deduced from the spectrum of atomic hydrogen.
- the spectrum of the light emitted inside the "pearl necklace" of supernova SNR1987A: it is strongly redshifted, so that by Hubble the supernova would be 2 billions light-year away while by light echoes, the distance is 162 000 ly. It is remarkable that light emitted by the ring is nearly not redshifted. Both types of beams cross hydrogen outside Strmgren's sphere, that is not excited atomic hydrogen does not redshift. There is only a difference between atoms inside and outside: inside they are generally excited, so that we may conclude that the redshift happens during a cross of excited atomic hydrogen only.

JMB, Can you provide a link to the SNR1987A data you posted above? thanks

You can look at arxiv:0801.0925 (physics). The last improvements will be presented at "Brass Tacks 2" conference in June and at "CCC2" conference in September.

JBM, I just did a search using the info you posted above and no matches were found. Is the number correct and if it is can you give me any clues what I'm doing wrong? thanks again

go to www.arxiv.org , type 0801.0925 in the box "search or article id" (right in the red banner), then physics in "Subject search and browse:", then Go in the red banner.
