OBSERVERS IN QUANTUM GRAVITY
The End of Time and the Many-Instants interpretation of Quantum Mechanics
I will review temporal relationalism, and the timeless approach to physics, with particular attention to its implications for quantum mechanics. A variant of Everett’s many-worlds interpretation of quantum mechanics emerges as a consequence of this point of view. I named this approach the `many instants’ interpretation of quantum mechanics. I will describe its features, and comment on its implications in light of recent findings, by my collaborators and me, regarding the cosmological arrow of time and the nature of the Big Bang.
