Doing Physics with Shape Dynamics
Speaker(s): Flavio Mercati
Abstract: Shape Dynamics is a theory of gravity which replaces relativity of simultaneity for spatial conformal invariance, maintaining the same degree of symmetry of General Relativity while avoiding some of its shortcomings. In SD several kinds of singularities of GR become unphysical gauge artefacts, an... read more

Ă€ la recherche du temps perdu - Templeton Frontiers Colloquia
Speaker(s): Flavio Mercati
Abstract: Augustine of Hippo declared he knew what time is until someone asked him. After 16 centuries we still largely ignore the true essence of time, but we made definite progress in studying its properties. The most striking, and somewhat intuitively (and tragically) obvious one is the irreversibility of ... read more

What is motion? What is time?
Speaker(s): Flavio Mercati
Abstract: I give an account of the Machian approach to dynamics, from Mach's critique of Newton to the work of Barbour, Bertotti, York and O'Murchadha, which culminated in the theory of Shape Dynamics, a new and original way of thinking about General Relativity. I conclude commenting on the present resear... read more

Shape Dynamics: Relativity Without Relativity
Speaker(s): Flavio Mercati
Abstract: I review the best-matching construction,  and the striking properties of a Jacobi-type action first introduced by Baierelein, Sharp and Wheeler. The simplest theories compatible with such an action principle must have a universal light-cone and gauge symmetry. I also descr... read more

Relative Locality, Kappa-Poincaré and the Relativity Principle
Speaker(s): Flavio Mercati
Abstract: I briefly introduce the recently introduced idea of relativity of locality, which is a consequence of a non-flat geometry of momentum space. Momentum space can acquire nontrivial geometrical properties due to quantum gravity effects. I study the relation of this framework with noncommutative ge... read more
