Scientists May Have Detected a Signal That Could Change Astronomy Forever
Scientists think they may have spied the universe’s “gravitational wave background” after more than a decade of searching.

In 2015, scientists snagged the first detection of a gravitational wave, a ripple in the fabric of spacetime. The achievement marked the beginning of an entirely new field of astronomy and earned the 2017 Nobel Prize in Physics. Now, emerging research suggests that we may be on the cusp of yet another major milestone for gravitational wave astronomy: the detection of the so-called “gravitational wave background.”
The discovery of gravitational waves continues to be one of the most consequential breakthroughs in science because it allows researchers to examine cataclysmic events, such as the mergers of black holes, that could never be spotted with traditional light-based astronomy.
