Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

A unified theory of everything has long eluded scientists due to gravity being irreconcilable with the three other fundamental forces (electromagnetic, weak, and strong) described using quantum ...

"By understanding quantum gravity, we could solve some of the mysteries of our universe — like how it began, what happens inside black holes, or uniting all forces into one big theory." ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Scientists demonstrate that quantum networks of clocks offer a new way to explore the interplay between quantum mechanics and curved space-time. Quantum networking is advancing rapidly across the ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has ...

n this illustration, a pulsar (PSR J0337-1715) ... "At some level, the majority of physicists believe that Einstein's theory of gravity, called general relativity, is correct.

Einstein predicted how gravity should work at the largest scales. And he was right, suggests new research. When Albert Einstein introduced his theory of general relativity in 1915, it changed the ...

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

A British theoretical physicist has developed a theory that could solve one of the universe's biggest mysteries: why its rate of expansion is accelerating rather than slowing down, as predicted by ...
