Geometric Foundations of Gravity 2025

is a conference dedicated to the various approaches to gravity that venture beyond the basic formalism of general relativity, i.e., the description in terms of a massless metric field in Riemannian geometry derived from the Einstein-Hilbert action. The topics will range from the foundational issues to the applications in cosmology, gravitational waves, black holes, and other objects. The meeting will take place on June 30 - July 4, 2025 in Tartu, Estonia. It is a continuation of a series of earlier conferences and workshops on the related subjects.

The topics under discussion include for instance:

• Extensions of general relativity (metric-affine gravity, Poincare gauge gravity, scalar/vector/tensor gravity, teleparallel gravity, massive gravity, bi-metric gravity, etc)
• Phenomenology of extended gravity (black holes, ordinary/neutron/boson/grava stars, gravitational waves, cosmology, dark energy, dark matter, galaxies, early universe etc)
• Beyond Lorentzian geometry in classical and quantum gravity (doubly/deformed relativity, standard model extension, Hamilton geometry, Finsler geometry, etc).

The last day of the conference is planned for hands on tutorial workshops on using computer algebra in gravity theory calculations, focussing on free specialized software packages Cadabra and SymPy (tensor).

The conference is organized by the gravity research group at the Laboratory of Theoretical Physics, Institute of Physics, University of Tartu.
