How did the big bang sound like? New data from the Planck cosmology probe provide new data for more ‘high-fidelity’ rendition of sound. The following videos present a high-fidelity and high-quality ‘remix’ audio version of the origin of the universe in light of these new data in a short version and a long version:
A bit of history now: 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. In space, no one can hear you scream. However, 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. The initial sound waves left a “fingerprint” on the cosmic microwave background in the form of temperature variations. 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. – Daily News
