# Geometric Foundations of Gravity 2023

is a conference focusing upon the various approaches to gravity that go beyond the usual framework of general relativity. The topics will range from the foundational issues to the applications for cosmology, gravitational waves, black holes, and other objects. The meeting will take place on **19-22 June 2023** in Tartu, Estonia, while remote online attendance can be also made possible when necessary. It is a continuation of a series of earlier conferences and workshops on the related subjects.

The theories 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, …)
- Astrophysics in Extended Gravity (black holes, ordinary/neutron/boson/grava stars, gravitational waves, strings, wormholes, binary systems, …)
- Cosmology in Extended Gravity (dynamical system analysis, observations and constraints, dark energy, dark matter, inflation, early universe, galaxies, …)
- Beyond Lorentzian Geometry in Classical and Quantum Gravity (doubly/deformed relativity, standard model extension, Hamilton geometry, Finsler geometry, …).

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