If we start with Minkowski Spacetime and take the global limit c → 0 seriously, it yields a spacetime which is utterly unfamiliar to our intuitions, yet consistent and intelligible. In this spacetime, motion in space is impossible and a novel coordinate transformation I callthe time-Galilean transformation describes aging without motion. I argue that this transformation fits the role of unitary time evolution in quantum mechanics because a) quantum states can always be decomposed in terms of a superposition of stationary states (energy eigenstates), and b) quantum motion is fundamentally different from classical motion. I take this as evidencefor a modal distinction between the classical and quantum worlds. I concretize this idea with the introduction of what I call the Heisenberg Interpretation, which interprets quantum states as a certain kind of pure physical possibility. The interpretation makes novel predictionswith respect to the interface between quantum theory and Einstein’s general relativity arising from the disinction between possibilities and actualities in spacetime.*Please note*: during the Conference, I found out that what I called the time-Galilean transformations had been previously discovered and is known as the Carrollian transformations. I left the poster unchanged because I wanted it to be a record of what conference participants saw.
