General relativity and gravity

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies of gravitational waves and observational studies of gravitational lensing, as well as tests of general relativity and laboratory experiments.

    Examining and comparing many of the definitions of a black hole, it is concluded that the profusion of different definitions is a virtue that makes the investigation of black holes possible and fruitful in many different kinds of problems.

    KAGRA is a new gravitational wave detector being built in Japan. Unlike LIGO/Virgo, it will operate at cryogenic temperatures with sapphire mirrors. KAGRA will help improve the localization of gravitational wave detections and determination of the source parameters.

    The stunning picture of a black hole shadow that was released by the Event Horizon Telescope highlights the power of collaborative projects, as no single person, telescope or nation could have captured such an image.

  • News and Views |

    While the measurements of the Hubble constant from the local distance ladder and the cosmic microwave background radiation appear to disagree, given a sufficient number of localized detections, gravitational waves may possibly shed light on the tension.

    General relativity was first experimentally verified in 1919. On the centennial of this occasion, we celebrate the scientific progress fuelled by subsequent efforts at verifying its predictions, from time dilation to the observation of the shadow of a black hole.

    Do black holes rotate, and if yes, how fast? This question is fundamental and has broad implications, but still remains open. There are significant observational challenges in current spin determinations, but future facilities offer prospects for precision measurements.
