Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

For a long time, scientists knew of a “gravity hole” beneath Antarctica—an area with particularly weak gravitational force. Considering the various threats currently faced by the region, scientists ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated ...
