Live blogging: Vidotto

Vidotto argues that both QM and GR are relational in an important sense.  In both theories, understood properly, everything observable and measurable amounts to the relationship between one system and another.

In GR and QG, this leads to a kind of locality: all interactions are between contiguous systems.

Audience: how does this square with EPR non-locality?  Vidotto: Relational QM resolves the EPR ‘paradox’ by allowing a way of understanding what’s going on without anything non-local happening.
