The cosmological constant and the physics behind dark energy that accelerates the expansion of the universe remain among the biggest mysteries in theoretical physics. An intriguing possibility is that these problems stem from extrapolating Einstein’s General relativity from the Solar system to the far infrared cosmological scales. In the other extreme, at the ultraviolet regime Einstein’s theory encounters notorious infinities resulting in spacetime singularities and obstacles to quantisation, which suggest new gravitational physics with possible repercussions to early universe physics.
The program will bring together experts in various aspects of gravity and cosmology, enabling to establish new links between fundamental physics and cosmological and astrophysical experiments from the fruitful interface of extended theories of gravity.
The main themes of the conference will include:
- Massive and bimetric theories
- Nonlocal theories
- Screening modifications of gravity
- Vector-tensor theories
