Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to ...

This larger gravitational force between two bodies relies on something called the gravitational constant that is used to calculate the relative gravitational force between two objects.

Renowned experimental physicist, Nobel laureate and Massachusetts Institute of Technology Professor Emeritus Rainer Weiss, ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the ...

In 2010, renowned string theory expert Erik Verlinde from the University of Amsterdam and the Delta Institute for Theoretical Physics proposed that gravity is not a fundamental force of nature ...

The movie Gravity had everyone spellbound with its gripping portrayal of spacewalks and the perils astronauts encounter ...

While gravity's effects can clearly be seen on the scale of things like planets, stars and galaxies, the force of gravity between everyday objects is extremely difficult to measure.

Quantum particles can feel the influence of gravitational fields they never touch Scientists reveal that the Aharonov-Bohm effect also applies to gravity ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today.

New study proposes using atomic clocks to probe the intersection of quantum mechanics and general relativity in spacetime.
