According to Einstein’s Theory of Relativity, space and time are inextricably connected. In our Universe, whose curvature is barely measurable, the structure of this spacetime is fixed. In a ...

Disclaimer: I am very much a physics noob. This might be a nonsensical question. That spacetime can be curved or warped is something I can grasp, but I keep getting stuck on one specific aspect of how ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

In 1797, English scientist Henry Cavendish measured the strength of gravity with a contraption made of lead spheres, wooden rods and wire. In the 21st century, scientists are doing something very ...
