Big Bang Really a Big Hum

Posted by michael on from the letdown dept.

benna writes "The New Scientist reports, 'The Big Bang sounded more like a deep hum than a bang, according to an analysis of the radiation left over from the cataclysm. Physicist John Cramer of the University of Washington in Seattle has created audio files of the event which can be played on a PC. "The sound is rather like a large jet plane flying 100 feet above your house in the middle of the night," he says.' Apparently the idea for the project came from an 11 year old."

    The reason you can't hear sound in space is because it's almost a vacuum. Back around the time of the Big Bang, matter was packed much closer together and density was far higher. Much higher, for example, than the density of the Earth's atmosphere. So yes, sound vibrations could propagate around in the early universe.
