A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when ...

Gravitational distortions produced by distant galaxies show a slight—but notable—disagreement with Einstein's predictions.

The study says that the gravitational distortions observed in distant galaxies exhibit subtle discrepancies with the ...

Dark matter, a mysterious substance thought to make up most of the universe's mass, has puzzled scientists for nearly a ...

Black hole light echoes are an extreme form of gravitational lensing. To measure the masses and spins of black holes, ...

It states that complex gravitational theories in a high-dimensional ... CFT stands for conformal field theory, which ...

Why is the expansion of our universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

Exactly how deep can be calculated using the theory and the group has now verified this using data from the Dark Energy Survey. Using gravitational lensing, they have determined how deep the ...

The theory, which Einstein published in 1915 ... and track their movements in the strong gravitational field of a companion pulsar," Professor Ingrid Stairs from the University of British Columbia ...

This review of experimental gravity provides a detailed survey of the intensive testing of Einstein's theory of gravity, including tests in the emerging strong-field dynamical regime. It discusses the ...

All matter has a gravitational field that attracts other objects. The more mass an object has, the greater its gravitational field will be. For example, the Earth has a greater gravitational field ...

A timely book which offers a simple and clear introduction to the theory of general relativity and its modern applications to cosmology, astrophysical black holes, and the exciting field of ...
