John Cramer, professor emeritus of physics at the University of Washington in Seattle, has created a high-fidelity rendition of the sound of the Big Bang and the noise generally believed to have accompanied the early development of the universe.
This is the second attempt for Cramer, who in 2003 generated a 100-second recording representing sound from between 380,000 years to 760,000 years after the Big Bang. Cramer updated his recordings with new, more detailed data produced last month from the European Space Agency's Planck satellite mission.
