The Universe Is 13.73 Billion Years Old

CaptainCarrot writes "Phil Plait, aka The Bad Astronomer has summarized for his readers the new results released by NASA from the Wilkinson Microwave Anisotropy Probe (WMAP), which has been surveying the 3K microwave radiation left over from the Big Bang. Some of the most interesting results: The age of the universe is now known to unprecedented accuracy: 13.73 billion years old, +/- 120 million. Spacetime is flat to within a 2% error margin. And ordinary matter and energy account for only 4.62% of the universe's total. Plait's comment on the age result: 'Some people might say it doesn't look a day over 6000 years. They're wrong.'"

    Well, it's a sure bet that she's younger than 13.73 billion years old.

    Can't say the same thing about my ex-wife, however.
