Expanding Universe, Big Rips and heat Death

Some recent scientific articles that popped my interest.

Well, the second article suggests the universe had no beginning and may have no end.

The third article suggests that the end "the Big Crunch" will occur in "a few tens of billions of years" which means the universe is still relatively young -- barely out of its teens so to speak.

The first article says that the universe may end in about 2.4 billion years, in which case it has already had 90% of it's life expectancy.

But the human race will not last anywhere near that long, so i guess i shouldn't worry.

It didn't have a beginning?
That doesn't seem right. :o

2.8 billion years?
I think they better look at their calculations again. :o

I tend to go for the heat death option which will be around 22 billion years in the future and total matter dispersion 100 million after that. Or a steady state option. Depends on how much dark matter there is, causing gravitational collapse, or how much dark energy there is, causing increased expansion.

I wish Earth's future looked as long. :o

Interesting...thank you for these! Definitely gives food for thought!
