comment What is the explanation for rapid inflation just after the big bang?
Afaik, there is no physical reason for it. Inflation is a model to explain some observations, but I never heard about forces or conditions which caused it. I hope someone more expert can say something.

comment Are there a lot of collisions between stars in the core of the galaxy?
Very good, thank you. It seems I was wrong. But, from a quick look at the paper, it seems there are no observational evidences for this, even if many arguments point to the expectation of such events.

Where did you read that redshift proves expansion is accelerating?

comment Could light be dark matter?
In this way, you are assuming that light gravitates much more than ordinary matter.

comment If the Universe is infinite, why isn't it of infinite density?
It seemed so from your question. Could you refer to the source which gave you these information?

Having infinite number of hydrogen atoms is not a direct consequence of an infinite Universe. You must revise your hypothesis.

Not really, stellar collisions are a rare event. I'll try to make an answer in a while.

comment Metallicity: What are the metallicity values of various galaxies?
Can't grab it. Here is a catalog: mpa-garching.mpg.de/SDSS/DR4/Data/stellarmet.html but is a bit of work.

Do you need the exact values? And just out of curiosity: why?
