In June 2023, scientists around the world announced the first official detection of the gravitational wave background — a cacophonous symphony of gravitational waves coming from every direction in space. Buried within that cosmic noise, there may be a primordial signal from the Big Bang. One day, scientists may be able to tease it out, and study the oldest signal in the universe.
