B Is there a probability in QM that an event happens at time t?

Click For Summary
In quantum mechanics, the probability amplitude A(x,t) indicates the likelihood of a particle being at position x at time t, while the discussion raises the question of whether a time probability amplitude B(y,t) can be defined for events occurring at specific times. The conversation explores the implications of measurements in limited regions of spacetime, referencing Wightman axioms and their correlation functions. A significant point of contention is the interpretation of probability densities and the quantum Zeno effect, where frequent measurements can inhibit event occurrence. The discussion highlights the complexities and nuances in understanding quantum probabilities and their implications in theoretical frameworks.
