?Are there any such thing as minor changes? ,
Remember that movie about a girl running for the Subway,
In one She makes just as the door starts closing, in the other the door closes in her face, and she has to wait ten Minutes for the next train.
The Movie then tracks the Changes in Her life caused by this.
I can envision a entire different TL based on whether You had Ham & Eggs, v Bacon & Eggs for Breakfast yesterday.
There is also the Question of Your view of the Multiverse, and how Branching works.
Those that argue for it taking time [Information Theory] envision the new universe as a twig, starting at the POD and Growing over time into a separate branch.
As such Washington being shot at the Battle of Trenton, Christmas Eve, has no effect on King George flipping a coin to decide between Ham or Kippers, for Christmas Breakfast.
However there is the Idea that the new ATL appears, Instantly [ Quantum Theory], as a full Branch, complete and Distinct.
Under this view, King George's coin toss is a new completely random event, and can be be different than the result in OTL where Washington wasn't Shot.
Personally I prefer the first Theory, As It avoids the -- Every atom any where in Your Universe that that Zigs instead of Zagging, creates a new Universe-- Problem.
This Quantum Theory does however seem to be more in tune with Shroderners Cat.
