The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...
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 ...

The study of gravitational dynamics interweaves the classical and quantum realisations of gravity, employing both traditional methods and modern amplitude techniques. At its core, the subject ...
We don’t often think about gravity, the invisible force that anchors us to Earth, as it always seems constant and dependable. However, it will slightly vary, sometimes by enough to make you weigh ...
The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase in ...
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 ...
To find features like groundwater under Earth's surface — or under the surface of another world — scientists can sense the subtle marks those features leave in the planet's gravitational field. But ...
We explore if there is a true connection between light and gravity. We know that gravity exerts its pull on light, and we have an explanation for why. Actually, we have multiple explanations that all ...
