A Chronophysics Primer
For ordinary life, four dimensions are enough to operate in: x (length), y (width), z (height), and t (time). The placement of any object at any given space-time can be plotted with these five coordinates. However, when time travel is involved, a fifth dimension is necessary: Metatime (m). The traditional way to determine Metatime is by measuring it in “ticks,” and one metatime unit, or tick, passes each time a time traveler leaves the timeline and re-enters it. In this way, one can track the changes to the timeline with a method of causality similar to ordinary timekeeping.
Example: Albert decides to make a change to the timeline, at AD 1963 – Albert is going to save John F. Kennedy from assassination. Albert both leaves from their original space-time, t: AD 2009, m: Tick 0. Meanwhile, Albert’s friend Bob lives in AD 2009.
|1963 |Tick 0 |2009 A, B
After arrival, Albert is at t: AD 1963, m: Tick 1, Bob is at t: AD 2009, m: Tick 1. Albert’s arrival (and subsequently prevention of the JFK assassination) creates Tick 1’s altered time, creating an alternate version of Albert, Albert1, native to Tick 1, never decides to go back in time.
|1963 |Tick 1 |2009 A A1, B1
However, alternate Bob, Bob1, decides to return to 1963 and stop Albert.
|1963 |Tick 2 |2009 B1,
Bob1 arrives at 1963/2, and kills Albert just after he arrives. Now, it is important to note that from the viewpoint of Albert, he arrives from Tick 0 to Tick 2, with no memory of Tick 1—but his actions in Tick 1 created Tick 2 by spurring Bob on.
Because any time travel leaving from one tick to the next occurs simultaneously from a metatime standpoint, it is important to take into account when synchronizing efforts within a group, or when dealing with a rival time traveler.
Example: Archie and Brian both decide to make changes to the timeline, one at AD 1963, and a second at AD 1981—Archie is going to save John F. Kennedy from assassination, and Brian is going to ensure that Ronald Reagan’s assassination attempt succeeds. They both leave from their original space-time, t: AD 2009, m: Tick 0.

After arrival, Archie is at t: AD 1963, m: Tick 1, Brian is at t: AD 1981, m: Tick 1. However, the difficulty is this: when Archie makes his change at 1963/1, it affects Brian—when he arrives at 1981/1, he finds that since JFK survived, the events that led up to John Hinkley’s assassination attempt changed. Here we posit two possible scenarios: 1. JFK’s survival led to Reagan never being elected, in which Archie did Brian’s job for him. 2. Reagan is still President, but the small circumstances have changed, from Hinkley not being involved, to something as small as Reagan’s itinerary being changed, preventing Hinkley from going forward with his plan as it occurred in Tick 0. In scenario 2, Brian has to integrate Archie’s changes into his own plan in order to succeed.
