A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed ...

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 ...

Physicists have proposed a modified version of Einstein’s general relativity, called quadratic quantum gravity (QQG), that could eliminate the Big Bang singularity and naturally produce cosmic ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...

What if the technology you use every day depends on a subtle distortion of time itself? The answer lies in a century-old idea that still shapes the modern world.
