In physics, a center of gravity of a material body is a point that may be used for a summary description of gravitational interactions. In a uniform gravitational field, the center of mass serves as ...
NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets.
A new planet-wide electric field that is as fundamental to Earth as gravity has been discovered in a major scientific breakthrough. The ambipolar electric field, which begins 150 miles above the ...
