Astronomers have, for the first time, measured the recoil speed and direction of a newborn black hole using gravitational waves. Data from the 2019 event GW190412 revealed the remnant shot away at 50 km/s. This breakthrough shows gravitational waves can reconstruct full 3D motion, offering new ways to connect black hole mergers with light signals.
