• Title: A single space-time is too small for all of Wigner's friends
• Authors: Jacques L. Pienaar,
• Abstract summary: Recent no-go theorems on interpretations of quantum theory are shown to have an unexpectedly strong corollary. One cannot reject AOE and at the same time assume that the observed events' in question can all be embedded within a single background space-time common to all observers.

• Abstract: Recent no-go theorems on interpretations of quantum theory featuring an assumption of `Absoluteness of Observed Events' (AOE) are shown to have an unexpectedly strong corollary: one cannot reject AOE and at the same time assume that the `observed events' in question can all be embedded within a single background space-time common to all observers. Consequently, interpretations that reject AOE appear incompatible with a `block universe' view of space-time.

  We employ methods from descriptive set theory to show that no complete observable on rich enough collections of spacetimes is Borel definable. Our results remain true even after restricting the space of solutions to vacuum solutions. We discuss the next steps in a research program that aims to further uncover this novel connection between theoretical physics and descriptive set theory.

  We review the Montevideo Interpretation of quantum mechanics, based on the use of real clocks to describe physics. Recent results on quantum complexity provide additional support to the type of global protocols used to prove that within ordinary -- unitary -- quantum mechanics no definite event occurs. We show that, if one takes into account fundamental inescapable uncertainties in measuring length and time intervals due to general relativity and quantum mechanics, the previously mentioned global protocols no longer allow to distinguish whether the state is in a superposition or not.

• A strong no-go theorem on the Wigner's friend paradox [0.0]
  We prove that if quantum evolution is controllable on the scale of an observer, then one of 'No-Superdeterminism', 'Locality' or 'Absoluteness of Observed Events' must be false. We show that although the violation of Bell-type inequalities in such scenarios is not in general sufficient to demonstrate the contradiction between those three assumptions, new inequalities can be derived in a theory-independent manner.
