Hi everyone,

Could someone tell me the details on how to calculate the age of the universe?
I've read online that it is about 13 billion years old but I can't find anywhere that tells me how they got to this number without confusing the hell out of me. Can anyone fill me in?

Thanks.

Hi TheSpecialist, welcome to these Forums!
How do you find the age of the universe? Try here post #26, and here, post #66.

I hope these help.

Hi TheSpecialist, and also welcome. There are several different ways of estimating the age of the universe and all of them yield similar results:

WMAP has provided what is believed to be the most precise estimate to date - 13.7 billion years.
