But even with that incredibly small gravitational field, scientists have devised clever experiments to measure it. In 2021, a team of scientists at the University of Vienna in Austria took two gold ...

Scientists measured the gravitational field of an object with a mass of just 90 milligrams A gold sphere on a horizontal glass beam responds to the gravitational pull of a neighboring sphere (right).

A layered Earth. (Courtesy: iStock/AlexLMX) The Earth is not a perfect sphere. This makes very precise modelling of our planet’s gravitational field rather tricky. To simplify the maths, scientists ...

The crater was first detected as a huge dent in Earth's gravitational field. Initial ground-based seismic and gravity surveys already indicated that the crater was huge — around 150 miles (240 ...

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 ...

Effective Field Theory (EFT): A framework that simplifies complex interactions by integrating out high-energy phenomena, allowing for accurate descriptions of long-range forces.
