It’s the instant that separates the past, a period of time when the outcome has a probability distribution around its possible values, from the present in which the outcome is a simple constant number. I sure don't claim to be a QM expert, but isn't this almost the exact definition of the wave function collapse when "observed", and so then are the two related in some mathematical way?
