Is the universe considered young or old?
Is 14 billion years since the big bang like an infant, or is it a middle ager?
I read some clickbaity articles that are all about the end or death of the universe, makes it all sound very old. Before our sun there were endless other suns already burnt out, and all that.
Our solar system formed what, 5 billion years ago? So it's like one third of the universes' lifetime. That doesn't seem much.
I wonder what astronomers would have seen five, ten billion years ago when they looked into the skies, deep into the universe. It must have been a lot denser populated with stars, a lot brighter.
Weird when you think about it.
