A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

Scientists aim to build the first graviton detector to explore gravity's quantum nature, despite significant challenges.

Bottom line: For decades, physicists have been trying to solve one of the greatest mysteries in science: how gravity operates at the smallest scales governed by quantum mechanics. While we have ...
