Three Kinds Of Dimensions II
Continued from here.
The Time Patrol Universe
A series of horizontal parallel straight lines.
An arrow pointing from left to right at the foot of the page.
A second arrow pointing up at one side of the page.
The parallel straight lines are successive timelines which can be numbered 1, 2, 3 etc.
The arrow at the foot of the page represents the direction of time within the successive timelines.
The arrow at the side of the page represents the order in which the timelines succeed each other.
A time traveler usually remains within a single timeline but occasionally departs 1 and arrives in 2 etc.
From our perspective looking down on the page, we can see that, when a time traveler departs timeline 1, that timeline continues to exist although, to inhabitants of timeline 2, it "does not exist and has never existed."
The time traveler arriving in timeline 2 knows that timeline 1 is in the past of the second temporal dimension extending up the page.
He may also think in a confused way that now it has never existed.
To be continued.
