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

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 ...

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 ...
