Kant says two different times must be successive, however, if we have a particle in two different states, at the same time, we have two different times coexisting, which isn't possible according to Kant's perspective on Time as an intuition, or form of knowing. Recently, Swiss physicist Nicolas Gisin published a number of papers attempting to clarify the issue around time, claiming that the issue is largely a mathematical problem, returning to an old mathematical language referred to as Intuitionist Mathematics, rejecting the idea of numbers with infinitely many digits.
