One Minus One = Not Possible
Historical speculative math and philosophy topic about subtraction, possibility, relativity, time, and whether zero tracks physical reality.
Please read cautiously, I talk about eternity and other subjects that make me dizzy. This is just my best understanding of what time is.
One cell splits into two. What is the math equation: zero plus two equals two, one plus one equals two, or one equals two? One apple is on the table. If eaten, at some instant of time the apple changes into empty or none, or one minus one. But in reality the apple still is something and only changes. The universe cannot recycle empty or none.
One possibility occupies one point in space and can split into two separate possibilities occupying two different points in space. The opposite can occur. Two possibilities occupying two different points in space can merge into one possibility occupying one point in space. There is also something that can prevent two possibilities from merging: a border, wall, or not possible.
Math describes change in time, what was and will be, or what was and is, at different instants. One minus one describes two possibilities, not one subtracting itself.
