..almost all dwarf stars have a positive radial velocity ..like its are flyng away ... the farest-ones have higther speed ..and the hotter-ones have higter speed ... ???

...i am a little old...in the old sense , the dwarf stars were very little , very heavy and very hot..
the idea of bigbang is very beautifull but with some contradictions.. drived with the idea that the temperature could influence the redshift , i began tosee the astronomy in this perespective .. and the dwarf cat. III/235A in CDS Strsbourg seemed to be rigth ...like in other situations for quasars , supernovae , galaxies etc...
can we repeit togheter the various found steps and to discuss ?
