Physical reality is small connected steps. The model reveals relationships that come from seeing the combination of small connected steps. But the model doesn't show the individual steps but only the results of the individual steps. So the appearance of a dog running is determined by the appearance of the location and distance of the dog not by the physical space to the dog. As the distance and location of the dog changes so does its appearance.

Reality is the sum of the parts. The model is a whole that can be seen as a whole or as individual parts. Memory, for example, is not the sum of all times but presents many times as one continuum or else as relations between individual times. Physically, individual times are in the past or in the fourth dimension depending on what you believe. But they are not here and now. So they are not physically present. But they are cognitively present.
One way to understand time is to think of a chain of dominoes. When the first domino falls the next domino is pushed over and this chain continues but the first domino does not physically touch the third domino or any other dominoes. So the twentieth domino (for example) is pushed or not pushed by the nineteenth domino. It is the nineteenth domino that determines what the twentieth domino will do. Time is the same. It is the last time that determines what will happen in the current time. It may seem that long ago times are a factor in the current time but only if that factor is carried forward through each successive time. In cognition we don't see each successive time so we might say that the first domino causes the twentieth domino to fall. That's could be true but only because of twenty objects falling individually.
The arrow of time can be seen in the dominoes. If the arrow of time reverses what will cause the dominoes to stand up? Not the laws of physics. Gravity will cause the dominoes to stay down. And as the new direction of time proceeds the dominoes will stay down. Proceeds means last to next. The action of the dominoes will create a chain of events that works the same if time is forward or backward. The laws of physics makes that true.
Time travel could be very difficult because with every step into the past, physics will turn the traveler around and head him into the future. The future is always ahead and the past is always behind. So physics has a direction but time doesn't. Thinking of time as a pulse may be the proper perspective.
Space does not create time. Motion creates time. In a motionless universe does time exist? If our brains are active it would seem so but it is the motion in our brains that create the perception of time and our perception would map our perception unto motionless space.
We set time 0 at a distant past and the present is moving away from the past. Alternatively we could set time 0 at the present and the past is moving away from us. In either case time is the same and only our perception has changed. We are on the time train or the time train is moving past us.
We can see time as a time line but does that explain movement at a certain time? The topology of a time line is not necessarily the topology of change. We should not put too much faith in partial representations. A representation of a representation may turn out to be misleading.
Does time move in space or does space move in time? The hands of a clock move in time and space but that is a result not a cause. Movement is movement in space because of time? Or because of physics? Is time only relationships? Time is relational to movement in one perception and relational to events in other perceptions.
Think of time in relation to a machine. The machine produces movement and events. Time is not the movements and events. Time is the relation of movement to a standard movement and also the order of events. Is the machine moving in space? Maybe not.
Is the past real? It doesn't have to be. The past is a real cognition. Cognition doesn't determine what the past is now. To know that we would need to physically contact the past. Moreover, time related to movement would make the past changeable like the present. To say that the physical past is exactly like the cognitive past is a rationalization.
