"The block universe is like a stack of events, with newer events at the top. In this stack, causing events are located below events that result from it. In other words, the events in the stack aren't arranged randomly; in terms of vertical placement at least, all events are arranged in a specific order of causation, with every resulting event located somewhere above its respective causing event. Causally related events are connected by channels of information flowing. So what we have is an unimaginably complex web of events and the information that connects them. "
