It took me a second to decipher the title.
The oldest stars were late bloomers?
Okay. I get it now. The first stars formed later than expected; to us, they are younger than expected. Hooray!
I think life in the universe is a precious thing no matter how expansive the universe is. Life that is conscious of the universe, as humans are, is especially precious. But the first stars formed — well, let’s put it this way:
Age of the universe: 13.798 billion years old.
First stars formed 560 million years after that.
First stars formed 13.238 billion years ago.
We’ve been around (so far) as humans, for about 100,000 years.
That’s 1/132,380-nth the age of the universe since stars formed. And without Googling anything, I’m going to say that stars are necessary for any kind of life we could relate to. If aliens existed in the primordial glow of the big bang, then more power to them.
As far as life we might label alien, let’s assume we need stars to exist in the universe.
We’ve been around for .00076% of the time. Around 8 ten-thousandths of a percent.
How long does any given intelligent species typically survive in this crazy universe of ours before it goes extinct? What’s the average life expectancy of an intelligent species, I guess. I’d like to know.
Because if intelligent life is out there, but we don’t overlap in time enough to make contact, then will we ever find each other? I hope so.
This is an article about the age of the first stars, but a beautiful narrative about the growth of our universe as well.
