“One of the Most Titanic Blasts in the Cosmos”: Gravitational Waves Support a “Forbidden Range” of Stellar Obliteration
Gravitational waves reveal an explosive “forbidden range” of stellar destruction so powerful that not even a black hole…
Gravitational waves may be responsible for dark matter in the universe
Dark matter is thought to exist everywhere, wrapping around galaxies and helping to shape the largest things in…
The physics of no return: What actually happens if you get pulled into a black hole

Expanding catalog of black hole collisions is rewriting the history of the universe
Between May 2023 and January 2024, a global network of gravitational-wave detectors picked up 128 new cosmic signals,…
Atomic light could be most practical way to detect gravitational waves
Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever so slightly. However, a…
New study shows gravitational waves alter atomic emission patterns
Quantum mechanics and general relativity are two of the most powerful theories in physics. Each has been tested…

Newly discovered ripples in spacetime put Einstein’s general relativity to the test
When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions travel far…
New catalog more than doubles the number of gravitational-wave detections made by LIGO, Virgo, and KAGRA observatories | MIT News
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form…
Scientists develop a new way to measure the expansion rate of the universe
For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe…
