Do we Live in a Middle Aged Universe?

I am teaching an Astronomy course at Waubonsee Community College at Plano, Illinois. Today the NYT reports the findings of D. Sobral et al. I post below the  arXiv  link to an article by Professor David Sobral, earlier, and the paper in question (arXiv).

We live finite lives. Our Sun is middle-aged, and now it turns out, our Universe also. At least as far as making new stars is concerned.

We are talking billions of years here, it is a sobering thought regardless.

We can have thoughts of immortality, but we do not have a single object we can claim is eternal. Our Universe was born, and in its way to a more complex future, we appear. Are we going to reach a Climax? Are we going to go down as a civilization, as a species, as a Universe?

No clue.

Here is the Royal Astronomical Society announcement.
