We don’t often think about gravity, the invisible force that anchors us to Earth, as it always seems constant and dependable. However, it will slightly vary, sometimes by enough to make you weigh ...

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 zero.

Satellites detected a strange gravity signal off the coast of Africa nearly 20 years ago, suggesting something unusual had happened deep within the planet to distort its gravitational field, according ...

In one particularly weird document, titled Negative Mass Propulsion, the authors propose nuking the Moon, as well as building ...

The study of gravitational dynamics interweaves the classical and quantum realisations of gravity, employing both traditional methods and modern amplitude techniques. At its core, the subject ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

Phobos is the larger and closer of the two natural satellites of Mars. Despite decades of Martian exploration, we still know very little about Phobos. Many fundamental properties of this small ...
