NIST and the Big Bang
BY Nancy Scola | Friday, May 15 2009
It's Friday, so let's geek out a bit. NIST, the office within the Commerce Department responsible for setting standards and measuring stuff, has released a rather awesome new video explaining their development of ultra-refined microwave sensors that just might be able to measure the universes gravitational waves "a trillionth of a trillionth of a trillionth of a second after the Big Bang." What they find might prove or disprove a theory called cosmic inflation, which holds that the universe we see before us went through an amazingly rapid expansion in the very instant after it first came into existence. Check it out.
