From an elsewhere of spacetime

Overview & Synopsis

Quantum realities seem to call for the existence of an elsewhere of spacetime. Examples taken from Quantum Mechanics, Quantum Field Theories and Bell's type experiments point to this disconcerting conclusion. How such an elsewhere can be thought of is the question addressed in this paper. How can quantum realities stand outside of spacetime, and if they do so what does it mean to enter spacetime? This conundrum can be fixed by focusing on the nature of quantum realities as it is revealed within the above three domains. Prospects are introduced in a gradual way and converge to what can be taken as a synthetic and universal characterisation of this spacetime's elsewhere.
