Relativity & Gravitation Group

The Relativity & Gravitation Group is part of the Department of Applied Mathematics and Theoretical Physics, which in turn is part of the Faculty of Mathematics of the University of Cambridge. The group was founded by Dennis Sciama in 1961, and is currently headed by Professor Paul Shellard.

It is internationally renowned for a number of important developments in Einstein's classical theory of gravitation, including the no hair and area theorems for black holes and the theorems indicating that singularities would occur both in gravitational collapse and at the beginning of the expansion of the Universe.

In recent years the group's main effort has been towards the inclusion of quantum effects, and the development of a theory of quantum gravity; in particular, the semi-classical quantization of black holes (leading, e.g, to the discovery of the thermal radiation produced by them) and the formulation of the Euclidean path integral approach to quantum gravity (leading to the no boundary condition for the Universe).

Furthermore, the group has expertise in the areas of supergravity, string and membrane theories of gravity, cosmology, cosmic strings and other topological defects in cosmology, numerical relativity and Regge calculus.

In addition, the group houses and operates COSMOS, the UK national cosmology supercomputer.

Stephen Hawking 75th Birthday Conference

2-5 July 2017

An international conference, entitled “Gravity and Black Holes,” marking the 75th birthday of Professor Stephen Hawking, will be held at the Centre for Mathematical Sciences, Wilberforce Road, Cambridge, UK, in July 2017.

This meeting will discuss recent advances in gravitational physics and cosmology, and the exciting future of this field following the recent direct detection of gravitational waves.

Registration for academic participants is now live.
