Because gravity is such a weak force, that would require masses of at least 22 micrograms, having quintillions of atoms.

Gravity and quantum mechanics are expected to meet at extreme energy scales, but time dilation could induce decoherence even at low energies affecting microscopic objects—a prospect that could ...

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 ...

Currently, the force of gravity can’t be explained in terms of quantum physics, but being able to measure its effects on smaller and smaller scales could unlock its secrets and perhaps reveal ...

For example, take the team's research into Isaac Newton's inverse square law, which stipulates that the gravitational force between two objects is proportional to the square of the distance ...

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

In 2002 the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Hannover was opened, as an extension of the already existing MPI (Albert Einstein Institute, AEI) in ...

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.

The 2017 winners of the Nobel Prize for Physics were announced today. One half of the prize will go to Ranier Weiss from MIT, while the other half is being awarded jointly to Barry C. Barish and ...

Einstein’s general relativity is a theory of gravity. It says that spacetime can be curved, and we feel the effects of that curvature as the gravitational force.
