International Conference on General Relativity and Gravitation is a recurring international scientific meeting focused on General relativity, Gravitational waves, Cosmology, and associated mathematical and experimental developments, founded in 1955. The conference has brought together researchers from institutions such as Princeton University, University of Cambridge, Massachusetts Institute of Technology, California Institute of Technology, and Max Planck Institute for Gravitational Physics and has been influential in disseminating results connected to Einstein field equations, Black hole thermodynamics, and Quantum gravity.

History

The conference originated in the mid-20th century amid renewed interest following work by Albert Einstein, Karl Schwarzschild, Subrahmanyan Chandrasekhar, J. Robert Oppenheimer, and Lev Landau, with the inaugural meeting in 1955 inspired by interactions among researchers at Institute for Advanced Study, Royal Society, Université de Paris, International Astronomical Union, and Niels Bohr Institute. Subsequent gatherings reflected major developments associated with Roger Penrose's singularity theorems, Stephen Hawking's black hole radiation predictions, and the rise of modern cosmology shaped by observations from facilities like Mount Wilson Observatory and missions such as Cosmic Background Explorer and Wilkinson Microwave Anisotropy Probe. The conference series paralleled formation of organizations including International Union of Pure and Applied Physics and collaborations like LIGO Scientific Collaboration and VIRGO Collaboration.

Historically organized under rotating committees from universities and societies such as International Society on General Relativity and Gravitation, host selection has involved bodies at University of Tokyo, University of Buenos Aires, University of Warsaw, and University of Cape Town. Meetings initially occurred roughly every three to four years with special symposia tied to anniversaries of figures like Einstein and Kip Thorne's peers; scheduling adapted to accommodate large collaborations like LIGO Laboratory, European Gravitational Observatory, and funding cycles at agencies such as National Science Foundation, European Research Council, and Japan Society for the Promotion of Science.

Noteworthy editions convened at venues including Princeton University (early Cold War era gatherings), Cambridge (United Kingdom) with links to Isaac Newton Institute, Walt Disney Concert Hall (as a major auditorium host in a city with California Institute of Technology activity), Moscow State University during Soviet-era exchanges, Kyoto University in Japan, University of Rome on occasions featuring Enrico Fermi-related histories, and Cape Town representing expansion to African institutions linked with Square Kilometre Array outreach. Sessions often coincided with satellite meetings at institutions such as Perimeter Institute for Theoretical Physics, Stanford University, Harvard University, University of Chicago, and Imperial College London.

Conferences highlighted breakthroughs in topics associated with Black hole solutions like the Kerr metric, stability analyses by Yvonne Choquet-Bruhat, numerical relativity developments tied to teams at Caltech and NASA, and advances in Gravitational wave detection culminating in LIGO and Virgo observations. Thematic sessions covered intersections with Quantum field theory, proposals such as Loop quantum gravity and String theory, baryogenesis and inflationary scenarios inspired by work from Alan Guth and Andrei Linde, and observational programs linked to Sloan Digital Sky Survey and Planck (spacecraft). Mathematical advances included studies of the Einstein–Hilbert action, energy conditions associated with Hawking–Penrose singularity theorems, and global analysis methods promoted by researchers from Courant Institute and IHÉS.

The conference series helped catalyze collaborations that directly contributed to milestones such as the first direct detection of Gravitational waves by LIGO, establishment of precision cosmology through missions like Planck (spacecraft), and integration of observational and theoretical programs across centers like European Southern Observatory and National Aeronautics and Space Administration. It also promoted curricula and research networks between universities including University of Cambridge, Yale University, Columbia University, and research institutes such as CERN and Max Planck Institute for Gravitational Physics.

Proceedings have been published by academic presses and societies including Cambridge University Press, Springer Science+Business Media, and proceedings series associated with International Astronomical Union and American Physical Society, often edited by organizers from Princeton University Press and distributed through libraries at Bibliothèque nationale de France and Library of Congress. Special issues in journals such as Physical Review Letters, Classical and Quantum Gravity, The Astrophysical Journal, and Communications in Mathematical Physics have collected selected contributions, while preprint circulation via arXiv archives has complemented formal publication pipelines.
