When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...
The conceptual architecture of black holes has undergone a radical transformation between 2024 and 2026, transitioning from the classical bottomless pits of general relativity to the intricate ...
General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...
“The main idea is to have a gravity gauge theory with a symmetry that is similar to the Standard Model symmetries, instead of basing the theory on the very different kind of spacetime symmetry of ...
For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...
Susskind, a physics professor at Stanford, and Cabannas, a former MIT math professor, offer an overview of Einstein’s theory of general relativity in this survey for specialists, the fourth volume of ...
Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...
© H. Pfeiffer, A. Buonanno (Max Planck Institute for Gravitational Physics), K. Mitman (Cornell University) A year ago, almost to the day, the LIGO-Virgo-KAGRA ...
General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...
