No no no. In order for this to be understood the assumed timeline must be abandoned such that all 3 test occur simultaneously. Past, present and future are mutually interdependent and cannot be separated by other than intellectual constructs.
Hmm. Have you been reading Dune lately? Or maybe 'lately' is the wrong word here. So let me try again: have you been reading the Dune series now, then, or in the future? I just finished the 5th Dune book and i'll be darned if what you typed couldn't have easily fit into one of the chapter headings there. Ahh but then again you're Amos the Prophet, so of course you'd view time differently than most mere mortals.
A good way to think about it is that we simply do not have a sensory input to detect the passage of time the way we have eyes and ears to detect size, shape, depth and location of objects in space.
Our perception of time is just that - our perception.
