The Sound of the Early Universe

The sound of the early Universe.

If you could hear the sound of the early Universe, this is what it may sound like.

The sound starts out as reasonably uniform and then decays down as the Universe expands.

Sound simulated by John Cramer of University of Washington based on Planck and WMAP satellite data.
