The quest for a consistent theory of quantum gravity is one of the most important
outstanding problems in theoretical physics. In the landscape of physical theories,
quantum gravity sits at the corner where all the physical constants (speed of light,
Newton’s and Planck’s constant) are finite. A region that is often overlooked is the
nonrelativistic gravity regime. Contrary to common lore, it is becoming clear that
the theory of nonrelativistic gravity is much richer than was so far appreciated,
containing much more than just Newtonian gravity. Thus, this offers an entirely
unexplored potential as a new route towards quantum gravity.
Central to this development is the formulation of non-relativistic gravity in terms of
Newton–Cartan type geometries, originally introduced by Cartan in 1923 to
geometrize Newton's law of gravitation. Moreover, a wide range of recent applications
of Newton-Cartan Geometry, spanning from string theory and holography to
condensed matter and biophysical systems, have spurred further interest and insights
into Newton-Cartan geometry and related non-relativistic geometries.
In this talk, I will present an overview of these developments and their future perspectives.
