The origin of Philosophy in ancient Greece actually started with the question how is change possible? So it looks to me almost as if philosophy has come a full circle to the same question. [If there is no time, then nothing can change and therefore nothing can interact with anything else.] That is in Relativity, time and space are laid out in such a way as they are almost interchangeable except with a minus sign in front of time. In that way of looking at time, there is no particular value "the present". And if there is no present, then change is impossible since change can happen only in the present.
But we also know Quantum Mechanics. And in Quantum Mechanics we have the two slit experiment and also the Bell inequality. [Bell's inequality is based on the Einstein Rosen Podolsky experiment. ] if we only had Bell's inequality, then we might say that things can have effects far away instantly. Or we might say that nothing has a time or space value until it is measured. Since we know Relativity is true and also we know that Nature violates Bell's inequality so we know the second idea is true. Things have no time value until measured. And this to some degree shows that Kant was right that time and space us how we measure things. They are dinge an sich--things in themselves that we have no window into. [What Bell's inequality shows is not strictly what Kant held, but it gets close. It shows that things do not have space time values until measured. But there is space time.
