 e\, as it is currently known in physics\, is a classical concept\, and our
  deepest theory of spacetime physics\, general relativity\, the classical 
 relativistic theory of gravity\, is a background independent theory of a d
 ynamical spacetime geometry. Quantum theory\, on the other hand\, is the d
 eepest theory we have of matter degrees of freedom\, and it is currently 
 formulated in a classical spacetime\, as an intrinsically probabilistic\, 
 contextual theory of non-classical\, interfering probabilities\, with a fi
 xed rule for computing those probabilities\, called the Born rule. I will 
 argue that the quantum nature of spacetime\, which apart from classical sp
 acetime also includes a dual spacetime that does not commute with classica
 l spacetime\, is the reason behind an intrinsically probabilistic and cont
 extual nature of quantum theory\, with the fixed Born rule. So\, quantum t
 heory teaches us something new about spacetime! This insight is important 
 for all applications of quantum theory. In the context of quantum gravity\
 , quantum theory is gravitized into a background independent structure wit
 h dynamical and contextual quantum probabilities. This proposal (quantum g
 ravity = gravitized quantum theory) can be checked experimentally by looki
 ng for intrinsic triple interference (which is identically zero in quantum
  theory\, as implied by the Born rule) in the context of massive quantum p
 robes. I will also discuss an explicit realization of such a gravitized qu
 antum theory as well as its empirical implications for the observed vacuum
  energy and the masses of elementary particles. Finally\, I will argue th
 at these lessons about quantum probabilities (and their generalizations) 
 can be applied in the context of complex adaptive (for example\, living) s
 ystems.\n\nhttps://eventreg.ads.ttu.edu/event/276/
