Out Of The Unstable Space-Time Zone

(Check out August. I said that it might end with 220 posts but it ended with 225.)

"Star of the Sea," 20.

"...at last [events] were out of the unstable space-time zone and could safely be left to themselves." (p. 629)

If we compare a temporal interval to a spatial distance, then we must imagine not a three-dimensional universe changing internally while it moves along that distance (Why should it move? What would it move in relation to? If it moves, then its motion takes time, therefore time is not the distance that it moves along.) but a four-dimensional continuum extending in that direction. Merely to extend is not to flow like a river. If there is such a 4D continuum, then, in each 3D cross-section, conscious beings remember a succession of cross-sections in one direction but in the other. Memory gives such conscious beings an "arrow of time" but their "arrow" is like a static arrow symbol pointing in one direction, not like a real arrow flying through time.

CS Lewis refers to:

"...that place where those things remain that are taken off time's main road, behind the invisible hedges, into the unimaginable fields."
-CS Lewis, That Hideous Strength IN Lewis, The Cosmic Trilogy (London, 1990), pp. 349-753 AT CHAPTER 9, 559.

A road extends but travelers move along it. A fourth dimension, if there is one, extends but no one moves along it. If anyone did move in that direction, then their motion would take time, therefore the dimension moved along would not be time. There are realities beyond what we know. Lewis compares them to invisible hedges and unimaginable fields.
