Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed ...

A quantum probe for gravity: Physicists have detected a tiny phase shift in atomic wave packets due to gravity-induced relativistic time dilation – an example of the Aharonov-Bohm effect in action.
