A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological ...

We all know gravity as the invisible force that keeps us grounded. But what if it's not a force at all? What if it's a function? One physicist believes gravity might actually be one of the strongest ...

Space travel has always hit a wall with slow speeds and massive fuel needs. Gravitic propulsion systems offer a game-changing ...

In Newtonian physics, gravity was thought to be instantaneous. But in Albert Einstein’s general theory of relativity, the speed of light, c, is the fastest possible speed for any interaction that ...

Aerodynamics explains how airplanes fly through the interplay of four fundamental forces: lift, weight, thrust, and drag.
