Anyone who wishes to attend this talk is welcome.

Abstract:

Relativistic spacetime, according to many quantum theories of gravity, does not exist, fundamentally. This threatens the very possibility of the empirical confirmation of these theories. Their empirical coherence can be restored by securing the emergence of spacetime from the fundamental non-spatio-temporal structures. Establishing this emergence requires not just mathe-matical limits and approximations, but also a successful argument that these technical procedures result in appropriately local `beables’. We show in the context of two programs in quantum gravity—loop quantum gravity and causal set theory—that a recovery of the merely functionally relevant features of spacetime suffices to this end.

    Very interesting topic. A pity I was traveling and could not participate. I wonder if a copy of the presentation is available and/or the event repeats.
