Even subjectively, "now" does not move through time. - Motion: nothing can move from one moment to another. If something exists in a certain moment, then it always exists. Moment: the snapshots of the observer are not successively in the present. They are not successively aware of their presence. They are all conscious, and subjectively they are all in the present. Objectively there is no present. - We also do not perceive time as flowing or transitory. - ...that the universe changes over time. But it does not move through time. I 250 There is nothing that can move, stop or flow. Since there is no time outside of it, it is not coherent to imagine that it can be changed or that it exists in several versions. Moment: a certain moment does not change. Therefore it cannot become present, or stop being present, because these would be changes. Flow of time: if we say when something happened, we do not need a "flow of time" any more than we need a "flow of space" if we say where something happened. >Time, >Past, >Present, >Future, >Change, >Processes, >Space-time, >Space-time points. I 265 In the multiverse, snapshots have no "time stamps". Other times are merely special cases of other universes. "Other moments in our universe" differ from "other universes" only from our point of view. >Quantum mechanics. I 265 Future: relative to an observer, the future is indeed open and the past is fixed. I 279 Does an acceleration lead into the past, if a deceleration would lead into the future? No. The outside world would only appear to be slowing down. Even if the brain was working at infinite speed, the outside world would appear to be frozen at a certain moment. I 284 Time machine: would be a place, not a vehicle. >Time travel. I 299 But here, changing the past is no different from changing the future, as we always do. - - - Gribbin III 236 Time/Deutsch/Gribbin: if time "flows", we would need a second type of time, which idles, as the "now" passes from one moment to the next - and a third to measure this time, and so on. Gribbin III 236 Time/Deutsch: there is no difference between snapshots from different times and from different worlds - past and future would be special cases of Everett's worlds. >Many Worlds Interpretation/Everett.}, note = { Deutsch I D.
