Their work, entitled “Working models for the gravitational field of Phobos”, was published in SCIENCE CHINA Physics, Mechanics & Astronomy, 2012, Vol 55 (2).

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

What’s new — As it turns out, all they needed to do was build, what the researchers are calling, the tiniest ever laboratory-created gravitational field.

A new Big Bang model does away with speculative elements, putting gravitational waves at the forefront of the creation of ...

Observations of astrophysical objects with weak gravitational fields and small spacetime curvature have provided no evidence of such fields so far.

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never ...

Hairy merger: artist’s impression of two black holes in-spiralling towards collision. (Courtesy: NASA) Black holes may defy the famous “no-hair” theorem by leaking residual gravitational ripples that ...

In quantum mechanics, charged particles like electrons can be sensitive to the effects of electromagnetic fields, even when placed in a region where both the electric and the magnetic fields are ...

Perhaps the best way to understand the electric field is to look at another field—the gravitational field. Suppose you have two objects, an apple and similarly sized (but much heavier) rock.
