Tiniest gravitational field ever created may solve a mystery Einstein couldn't Researchers are closer than ever to a grand unifying theory. by Sarah Wells Updated: Feb. 20, 2024 ...

Gravitational field A gravitational field is a model used within physics to explain how gravity exists in the universe. In its original concept, gravity was a force between point masses.

Massive sources -- things like particles -- have the analogue of a gravitational charge, while the curved fabric of space itself is the analogue of a gravitational field.

In a new Physical Review Letters study, researchers have successfully followed a gravitational wave's complete journey from the infinite past to the infinite future as it encounters a black hole.

But the part that makes this thing game-changing and truly revolutionary is that it’s the start of gravitational wave astronomy. An entirely new field! Christie: So a new tool AND a new field!

For example, the gravitational field strength on Earth is 10 N/kg whereas on Jupiter it is 24.7 N/kg. This means that a mass of 50 kg will weigh just over double on Jupiter than it would on Earth.

People around the world cheered yesterday morning (Feb. 11) when scientists announced the first direct detection of gravitational waves — ripples in the fabric of space-time whose existence was ...
