• Abstract: Extended Wigner-type experiments reveal a fundamental tension between the universality of quantum mechanics, the absoluteness of observed events, and the structure of physical reality. While recent no-go theorems suggest that these assumptions cannot be jointly maintained, their interpretation remains unclear. In particular, the claim that events are not absolute is often left at the level of an interpretive slogan, without a precise conceptual formulation. In this paper, we analyse the conceptual structure underlying these results and show that the non-absoluteness of events requires a precise formulation in order to avoid ambiguity. We argue that many existing approaches fail to provide such a formulation, either by implicitly reintroducing observer-independent structure or by leaving key notions underdetermined. Within this framework, Convivial Solipsism offers a coherent and fully articulated account of non-absolute events, preserving the universality of quantum mechanics while avoiding the need for a global viewpoint. We show in particular that this approach resolves the apparent conflict between perspectival outcomes and scientific intersubjectivity. These results suggest that scientific objectivity does not rely on observer-independent facts, but on the internal coherence of perspectival structures.

  We argue that the Wigner's friend paradox, the theorem of Bong et al and the theorem of Lawrence et al are all best understood as demonstrating that if quantum mechanics is universal. We also argue that these theorems taken together suggest interesting possibilities for a different kind of relational approach in which dynamical states are relativized whilst observed events are absolute.

  A measurement can be regarded as an absolute event, giving the same result for any observer in an irreversible manner. We argue that, when combined with the assumptions of locality and no-superdeterminism, regarding a measurement as an absolute event is incompatible with the universal validity of quantum mechanics.

• Quantum Mechanical description of Bell's experiment assumes Locality [91.3755431537592]
  Bell's experiment description assumes the (Quantum Mechanics-language equivalent of the classical) condition of Locality. This result is complementary to a recently published one demonstrating that non-Locality is necessary to describe said experiment. It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
