Atom interferometry may enable ways to measure gravitational waves without the destructive influence of laser fluctuations.

A modified form of Lagrange’s equations of motion will make it easier to account for energy loss in a mechanical system.

The surprisingly complex behavior of three gravitationally attracted bodies includes several previously unknown periodic orbits.

No cause for alarm, but new simulations show that less energy than previously thought is needed to form a black hole in a particle collision.

Microparticles suspended in an optical cavity may be a new way to detect gravity waves.

Contrary to the common view, the gravitational lensing from cosmic voids causes a brightening—not a dimming—of background objects, according to new calculations.

Existing or planned electron accelerators may be able to see the breakdown of general relativity.

New calculations of hypothetical “black hole bombs” set an upper limit on the possible mass of the photon and on the existence of certain dark matter candidates.

The gravitational version of the Aharonov-Bohm effect, where particles are affected by the gravitational potential in the absence of a force, could be demonstrated in a lab-scale experiment using ultracold atoms.
