Age of the universe...

Postby sky » Tue Dec 20, 2005 4:33 pm

I understood the age of the universe to be 13.7 billion years old. I have heard however that the hubble constant is being reviewed following the discovery of galaxies and stars older than this.

Can anyone confirm this?

thanks all!

How do they know that they are older than this? I thought that distant galaies were aged by their redshift. This would give answers that fitted into our old age of the universe (namely 13.7 billion years).
Interesting though!

No idea, I heard it on another forum, the gist was that the hubble constant was being disputed and the galaxies in question were 15 billion light years away, i.e. older than the universe, so therefore the universe is not 13.7 but at least 15 billion years old, can't find any collaborating evidence tho...
