Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Research conducted by two physicists from the National Institute of Standards and Technology (NIST) in the US reveals 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 zero.

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

started rising. As the ground rebounded in this fashion, the gravity field changed. “The Earth behaved much like putting your finger into a sponge ball and watching it slowly bounce back,” said ...

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 ...

A new model of the Universe suggests that modifying Newton's theory of gravity could do away with the need for dark matter. The model instead relies on an as-of-yet undiscovered form of gravity to ...
