Question Big Bang

1) What is theReal Age Of Universe?20 billions years based onHoof
-50KMS-1MPC-1 or Ho of100KMs-1MPC-1 in empty universe of10 or11 billion years?
2) Does WIMPS (wealkly interacting Massive particles ) also contribute to critical density of the universe? The universe contain about 1/10th as much as ordinary matter as critical density. Looking at critical density of universe, the universe suffer frrom short fall of ordinary matter consisting of proton neutrons and electrons as per Dr Pranab Kr Bhattacharya & Mr. Rupak Bhattacharya.
3) Neutrinos are Mass less orhave a mass? All accepeted models of universe so far in cosmology and particle physics assumes neutrinos are mass less.But really is it or it carries a mass of 17000Kev.
4) Whether universe is closed[ omega>1] or open[omega<1] or Flat [ omega=0] . if universe isOmega=1 then was nucleosynthesis in Big Bang was realy baryonic ornonbaryonic in quark hadron phase transition

I'm not sure why you are asking us. To fully explain the answers to your questions would take a large book. However. I can say that you have some old information, and that things are clearer now than they were. In a couple of weeks, we expect to see some new information released from the WMAP team. Read that carefully, and most of your questions will be answered.

The age of universe is when estimated from a cosmological model based on Hubble constant is 13.7+/-0.2 billion years and hubble value for H0 motivates the cosmologists to belief in Stedy state theory of Hoyel Bondi and Gold and then universe is same in all direction and in all place and expanding where matter must be continiously creating. How a hydrogen Ion will Know where it has to be created and when to be created in this universe.And probably steady state theory put the Big Bang theory in a big trouble. On the critical Density of the universe the question of Expansion of universe for ever actually depends whether it will expand for ever or it will expand for some time and then will collapse and will fall into Big crunch another singularity. The observed density of baryonic( Neutron Proton, Quarks etc ) gives 4.4% of Critical density for Ho=1 And then most of the matter of universe is non baryonic-

I am moving this thread into the Against The Mainstream section of this forum. Perhaps another mod may merge it with some other steady-state, big-bang-is-wrong thread.

MMM why would we need costant creation of matter? If the universe expand universally, the distances between the galaxies just becomes larger and larger (depressing thought in a way, for anyone who would like to go travelling into deep space once).
I see no need for hydrogen to be created, and therefore no need for the hydrogen to know where it should be created.

Is there not a contradiction in terminis in this quote?

Then how the universe evolved from its featureless state to its clumped structure of galaxies and super clusters ? whether this process worked bottom up with very large structure forming through merging of small subgalactic units or topdown process with large clusters forming before any galaxies? Next DoesCDM model can explain very large scale distribution of galaxies?CDM model always point towards a flat universe[Omega=0] and it assumes that universe had a mean critical density , universe expands for ever, >90% matter non baryonic.It do support Big crunch and galaxies formation is bottom up.Though CDM has many problems like density fluctuation & perturbation regarding the precise nature,associated with Eienstien De star cosmological model,universe will crash down one day on milky way/etc

Hi pranab, You are mostly asking straightforward questions now. Later today, the WMAP team will release some papers that will tell you as much as is currently known about the answers to your questions.

A language barrier is evident, as is a logic barrier. The website link is bizarre. The association between 'cytogenetics' and cosmology is nonsensical to me. It looks like a degree in bad science.
