You're right, you didn't suggest uniformity—my bad. Let's explore this.
Einstein's concept of time as a dimension, part of the fabric of spacetime, does imply that all moments exist simultaneously, in a sort of block universe theory. In this view, time travel would indeed require accessing different "points" in this four-dimensional spacetime.
Your idea of save points is intriguing because it imagines time as discrete snapshots that can be revisited or altered. While it simplifies some complexities of spacetime (like how gravity and speed affect time), it also introduces a compelling way to think about the existence and potential manipulation of past moments.
If each moment were like a save point, time travel could then be about navigating through these points rather than needing the entire universe to replicate itself. It offers a different perspective on how we might "move" through time.
It's these kind of creative concepts that push the boundaries of our understanding. What other theories or ideas about time intrigue you?
