The Age of the Universe

Some Universe Wallpapers

The best estimate we currently have for the age of the Universe is 13.7 thousand million years, plus or minus a few hundred million years.



This estimate follows from very accurate observations of the microwaves of the 3K background radiation that reach us from all directions.


Those observations only fit our models of the growth of the Universe if it is now that old.
