- description: Available now for your listening pleasure, a recording of our birth. Captured in hi-fidelity. A decade ago, American physics professor John Cramer released an audio file of a true golden oldie -- the sound of the theorized Big Bang that formed the universe. Now armed with new data from the Planck cosmology probe -- a European-led space observatory -- Cramer has released a remix. It's a remarkable audio update on the oldest collaboration imaginable. "In general, there are no sounds in space, because there is no air to vibrate," Cramer, a professor emeritus at the University of Washington, tells QMI Agency. He notes the old Hollywood tag line of "In space, no one can hear you scream, but adds: "The Big Bang is the exception to this, because the medium that pervaded the universe in the first 100,000 years or so was far more dense than the atmosphere of the Earth." He's traced compression waves -- "like ripples in a pool or the ringing of a bell" -- moving through a medium of the very early universe and resonating in it. "The initial sound waves left a "fingerprint" on the cosmic microwave background in the form of temperature variations," he explains. "If you were there then, you might hear something like the bottled sound, but the frequencies present then would be very much lower than the simulation." The audio has proven to be a hit with scientists. As well as Cramer's dogs, which he says react with barks to the low frequencies. All credit goes to Cramer for this recording. Credit for picture shown goes to the European Space Agency.
