New Study Explores How LIGO-Style Lasers Could Test Quantum Gravity
Gravitational waves, first directly detected in 2015, have opened a new way of observing the universe. Now, physicist Ralf Schützhold of HZDR proposes going a step further—actively interacting with these ripples in spacetime using powerful lasers. His theoretical scheme builds on LIGO-style interferometers, where intense laser pulses bounce repe...

Black Hole Kicked Away? Gravitational Waves Reveal Einstein’s Ripples in Spacetime
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.

Gravitational Waves Suggest Supercool Phase Transition After the Big Bang, Unveiling New Physics
In 2023, scientists detected faint ripples in spacetime, known as gravitational waves, which were initially attributed to a phase transition shortly after the Big Bang. This phase transition was thought to have occurred in the early universe and was believed to generate the low-frequency waves detected by pulsar timing arrays. However, recent resea...
