On The Subject of Universes

Think about our universe as a point.  That's pretty much all that it is, until you add time (I love time).

Time adds a dimension to our universe (it's the same item, but with more going on).  Essentially, our point has become a line.  Timeline.  You've heard this before.

Now it's guesswork, but based on my understanding, there are a ton of universes out there, with millions and billions of different things going on.  In order to account for this diversity, our lines need to be floating around in 3D space.  Think string floating around without gravity.  Timelines are usually more stationary than that.  More on this later.

If two timelines intersect, then the universe at that given point is exactly the same (happens more often than you would think).  Not that everyone's history is the same, but the physical actions of everyone and everything line up perfectly.  Usually, this happens right when someone makes a choice.

As you may have guessed, many universes can meet at the same point.


Parallel universes:

There may be similarities between the two--in fact, they are usually quite akin to each other--yet they do not share any moments, at any point in time.

Perpendicular universes:

At one moment, everything between the two words is exactly the same; one choice determines which universe you wind up in.

Most universes:

Seemingly random, intersect with other universes at different points, it is completely possible to jump from one to the other (where they intersect), but it doesn't have much impact on how you perceive the world.  This is a bit different when you throw time travel into things.

I hope that that's explanation enough.  John will be back any minute.
