This is what the birth of the universe sounded like | Mark Whittle
Summary
Astronomer Mark Whittle explains how sound waves from the early universe, detected in the cosmic microwave background, shaped the formation of galaxies. He demonstrates how these primordial vibrations, originally 50 octaves below human hearing, can be sonified to reveal a cosmic chord. Whittle connects this ancient acoustic era to modern galaxy patterns and shares a musical composition based on these frequencies, highlighting how humans are made of the same atoms that participated in the universe’s first symphony.
