On a bright spring morning 50 years ago, two young astronomers at Bell Laboratories were tuning a 20-foot, horn-shaped antenna pointed toward the sky over New Jersey. Their goal was to measure the Milky Way galaxy, home to planet Earth. To their puzzlement, Robert W. Wilson and Arno A. Penzias heard the insistent hiss of radio signals coming from every direction — and from beyond the Milky Way. It was cosmic microwave background radiation, a residue of the primordial explosion of energy and matter that suddenly gave rise to the universe some 13.8 billion years ago. The scientists had found evidence that would confirm the Big Bang Theory, first proposed by Georges Lemaître in 1931.

The light helps rule the Big Bang Theory out.

The mysterious signal means a steady state of the universe.

The universe was in a steady state without a singular beginning.

The radiation is a residual effect of the explosion which Lemaître theorized.
