Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

For more than 200 years, scientists have struggled to pin down the exact strength of gravity — and one physicist spent a decade chasing the answer while keeping his own results hidden from himself.

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team ...

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our Universe — which neither emits nor reflects light — remains unsolved. A team ...
