Gravity behaves predictably in your daily life. Drop a ball, and it falls. Planets loop around stars. On paper, the same rules should also govern matter spread across the universe. But the farther ...

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and ...

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

If gravity is the weakest of the four fundamental forces, how can the Sun’s gravity affect distant and low-mass objects such as those in the Kuiper Belt and Oort Cloud? It is true that gravity is ...

In the zero-gravity airplanes or vomit comet, why does stuff behave like there is no gravity when it is just falling? – Austin B., 11, Scranton, Pennsylvania I have flown many times in zero-gravity ...

Physicists have traced three of the four forces of nature — the electromagnetic force and the strong and weak nuclear forces — to their origins in quantum particles. But the fourth fundamental force, ...
