Has dark matter in the Universe become more popular then Neutrino theory?

Answer 1

I'm afaid that I don't really understand your question.

Are you asking if Astronomers are more likely to believe in dark matter than in the existence of neutrinos? In my opinion, yes, because I know of no astronomers who don't believe in the existence of dark matter, but there are many who do not believe in the existence of neutrinos.

Answer 2

Its not a question of popularity.

Work on neutrinos was once important to try to resolve what the total mass of the universe might be.

Now we have measurements that indicate that its mass is much larger than we can account for from observed stars etc. And we also know that the neutrino mass is too small to make up this difference.

So neutrinos remain important but are now known not to have enough mass to explain the observed (from the effects of gravity) mass of the universe.

Answer 3

i think so. i personally know more about dark matter than neutrino theory.

Answer 4

Yep .. Neutrinos contribute very little mass.
