One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

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 concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

Fine balance The researchers measured the gravitational field between two gold masses of 1mm radius each that are brought close to each other. (Courtesy: Tobias Westphal, University of Vienna) ...

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 ...

Zone of divergence: A section through the centre of mass, O, of a planet and the single point, S, on the surface of the planet that touches its Brillouin sphere. The point O is the centre of the ...

There are two fundamental classes of theories required to describe the entirety of the Universe. On the one hand, there's quantum field theory, which describes electromagnetism and the nuclear forces, ...

At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...
