Seeing Betelgeuse?
The small stars might be in part because the larger the star, the shorter its life. A G type star like ours has an average life of about 10 billion years, but a tiny M class can have a lifetime of 200 billion years. A giant like Sirius A only has a lifetime of 1 billion years. A super giant may only last 10 million years.
Many smaller stars have lifetimes longer than the age of the universe, which means some of the original stars might still be going. Living in the neighborhood of a super giant would probably not allow much life to get going. Just as life gets going the star 50 LY away super novas and wipes out the neighborhood.
That is interesting. Is it just mistaken dating? I've long been convinced the universe must be infinite, as no rational alternative exists in my view, and we were bound to find older structures as the "Big Bang" must have been merely a local event. Most of the neighborhood nearby what we see is probably cold, dead and black.
I'm thinking our local area (everything we can see) is actually unusually dense and that there's likely a black hole somewhere going 'big bang' somewhere all the time.
You made me ponder on whether The Big Bang is the result of God being bored and firing fireworks, or not.
