        Space Sounds - Sound of the Big Bang | It's Okay to Be Smart

Cramer from the University of Washington took the measurement data of the cosmic microwave background from ESA's Planck space telescope and converted the energy frequencies of the first 760,000 years of the universe into audible sound.
