Balzan Conference on Open Issues in Gravitation
March 24-26, 2026
at IHES - Marilyn and James Simons Conference Center
How to get to IHES

The Balzan Conference on Open Issues in Gravitation is part of the research project carried out at IHES with the 2021 Balzan Prize for Gravitation: Physical and Astrophysical Aspects, awarded to T. Damour.
Though gravity is the oldest investigated interaction both observationally and theoretically, it remains mysterious and challenging in many aspects.
This three-day conference will bring together leading experts in a wide range of topics related to gravitation. Besides offering an overview of the status of the field, the talks will address open issues in gravitation that are currently the focus of intense research, such as: gravitational waves, tests of General Relativity, numerical relativity, self-force, new approaches to Black Hole perturbations, extreme black holes, BMS, post-Minkowskian gravity, scattering amplitudes, high-energy scattering, effective field theory, etc.
The talks will be videotaped, thereby completing the collection of Balzan Lectures at IHES (available on carmin.tv)
