The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

Gravitational physicists explore the implications of the general theory of relativity, in which gravitation is a consequence of the curvature of space and time. This curvature thus controls the motion ...

Gravity is the force that keeps our feet on the ground ... This clip will be relevant for teaching Physics. This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA ...

ELLIE: Let's say we want to find out the force of gravity, their weight, acting on your physics teacher as they stand at the front of the classroom. JAMES: Good image. Now first, you would need to ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites ...

A collaboration between Nordita, the Nordic Institute for Theoretical Physics, hosted by Stockholm University, KTH and Google ...

Physics is a continually advancing field, with new discoveries occurring daily. Newton’s theory of gravity and Galileo’s ...

Even though dark matter is invisible—and, technically, still hypothetical—it is thought to be the driving force behind ...

This discovery was a watershed moment in physics and astrophysics ... One profound consequence of Einstein’s theory of gravity is that the fabric of spacetime can be warped and stretched ...

However, the discovery was also only possible because of a well-known concept in the world of physics: gravitational lensing ... that had been set loose by the forces of the galaxy cluster ...
