Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Kinetic energy has to do with the motion of an object—the faster it’s moving, the more kinetic energy it has. If you take a ...

Is General Relativity the correct theory of gravitation? Can gravity be used to detect new fundamental fields? A recent Letter appearing today in Nature Astronomy, authored by a researcher of the GSSI ...

Exact solutions in electromagnetic fields and gravitational dynamics offer a rigorous window into the fundamental interactions that govern our universe. By applying advanced mathematical ...

Your location in this Universe isn't just described by spatial coordinates (where), but also by a time coordinate (when). It is impossible to move from one spatial location to another without also ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

To find features like groundwater under Earth's surface — or under the surface of another world — scientists can sense the subtle marks those features leave in the planet's gravitational field. But ...
