The Radio Static That Turned Out to Be the Big Bang
In 1964, two engineers kept hearing a faint hiss in their antenna and blamed pigeon droppings before scrubbing every bolt. The noise was actually the afterglow of the universe's birth, and it won them a Nobel Prize. This is the story of how the biggest discovery in cosmology arrived disguised as an annoying glitch.
Listen in the Fylom app.
Bell Labs researchers discovered a persistent three-degree hiss while repurposing a twenty-foot horn antenna.
Engineers scrubbed bird droppings and taped antenna seams to rule out local interference for the noise.
The isotropic signal matched Princeton's prediction of relic radiation chilled by billions of years of expansion.
This discovery provided the observational evidence needed to favor the Big Bang over Steady State theory.
Cosmic microwave background fluctuations represent the gravitational seeds that eventually formed every galaxy.
Modern satellite missions used this ancient light to calculate the universe's age at thirteen point eight billion years.
