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 ...

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 ...

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 ...

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 ...

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 come ...

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 ...

In an extraordinary testament to the predictive power of Einstein’s theory of general relativity, a star system has been discovered that demonstrates extreme gravitational lensing. This observation ...
