Using a method similar to tuning an equalizer, scientists isolated a quiet overtone in event GW250114. Its confidence level rose from 82.5% to 99.9%, fully confirming Einstein's theory.

Collisions of neutron stars or black holes create ripples in spacetime—gravitational waves. Scientists need to know about such an event instantly to see its light. This is the story of GstLAL, a program that finds the signal in just 16 seconds and almost never shuts down. Thanks to it, out of 250 al
