If Now exists outside of time, then the measurement of time weather it’s measured as a loop, forward, backward, in a spiral, etc. would have no effect on the Now. From the Now’s perspective all of time has already occurred, is occurring, and has yet to occur all at once. If Now’s position is fixed, then it would appear in multiple timelines at once, and in multiple locations at once.

Time is simply a measurement of the constant of change, which is itself a paradox, something false that continuously proves itself to be false, or something in motion that continuously keeps itself in motion. So we can say something that is false is something that is mutable and movable. Then an object that is not false, outside of the constant of change, would be immutable, in-movable, and fixed, like the Now. Time would move around it, while it remains stationary and unaffected.
