Far below the surface of the Indian Ocean lies one of the most striking irregularities in Earth’s gravity field, a broad ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Gravitational fields as a research area encompass theoretical, computational, and experimental studies of how mass-energy curves spacetime and produces gravitational interactions, primarily within the ...

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 ...

Transformation optics in gravitational fields explores the design of engineered media that emulate the curvature of spacetime to manipulate electromagnetic waves. By mapping desired geometrical ...

Thermodynamic equilibrium in a gravitational field describes a state in which a fluid or gas under the influence of gravity attains a stationary temperature distribution that balances gravitational ...

Cast your mind back four years, and gravitational waves were the talk of the town. On September 14, 2015, the first detection of these ripples in space-time was made by the LIGO-Virgo collaboration, ...

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, ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

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 ...

Technically, every single object in the universe with mass or energy emits a gravitational field, and scientists have been able to measure the gravitational field of objects far smaller than a human.
