According to Physics World, physicists have developed a new model of how gravitational waves reveal dark matter's secrets. When black holes collide, nearby dark matter subtly warps their orbital dynamics. These disturbances leave traces in the gravitational-wave signals detected by instruments like LIGO. If the model holds up, it could give scientists a new way to study dark matter—one of physics' biggest unsolved puzzles—by analyzing the cosmic collisions we already observe.
