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
