What do you think a causal chain implies? The fact that if one were to see the whole of it, they’d see what fragment will appear at what point in time. My concept of time is accurate. Time and movement are one and the same. By movement I mean jumping from one fragment to another. The length of the fragment is the length of time. I’m not entirely sure how contraction or dilation works yet. No one is. It will be understandable once it’s described.
Time travel is possible.
