Thanks to my friend William Atkins for pointing out at iTWire that astrophysicists from Princeton and Johns Hopkins universities have determined the age of the universe more precisely, and it turns out to be a “little” older than previously thought.
The scientists have analyzed data from WMAP, NASA’s Wilkinson Microwave Anisotropy Probe, and have come up with an additional 20 million years.
WMAP definitively determined the age of the universe to be 13.73 billion years old to within 1% (0.12 billion years) -as recognized in the Guinness Book of World Records! So a mere 20 million years can be considered just a tiny amendment of the universe’s age!
This Basic Questions blog has a number of earlier posts about such cosmological matters. If you’re at all interested in cosmology, the WMAP site should definitely be on your must-see list. Since 2000, they say, the three most highly cited papers in all of physics and astronomy are WMAP scientific papers.
