Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

A researcher at Kyushu University and his collaborators have shown that continuous parameters in quantum gravity may not be ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

Albert Einstein postulated in his 1905 theory of special relativity that the speed of light in a vacuum is constant. Ever ...

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

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 ...

The gravity quantum field is calculated in flat spacetime. The curved classical metric is calculated using the expectation value of the gravity quantum field. At long last, a unified theory combining ...

Everything in the universe has gravity — and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

What if dark matter didn’t exist? Sure, scientists have never observed it, but they believe it exists because of apparent gravitational effects. But what if our current understanding of gravity was ...
