The result from CERN confirms expectations, but it's the first time gravity’s effect on the stuff has actually been tested. Reading time 3 minutes In the 95 years we’ve known about antimatter, ...

Did you know that moving a clock one inch toward the ground would result in a slower tick compared to the same clock positioned higher up? Gravity doesn't just pull things; it also bends time.

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Levon Pogosian receives funding from the Natural Sciences and Engineering Research Council of Canada. Camille Bonvin receives funding from the European Research Council (ERC) under the European ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. Using two HST images ...

The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...
