Now this could get interesting. If anyone has been following the development of "String Theory" this thread would strike home.
Einstein tried, but failed, to derive a theory of everything - gravity, energy, light, mass, etc. His E=(mc) squared (this program will not allow super script) is the theory that helped to develop nuclear power. It does not allow for gravity and therefore cannot be used as the theory that describes the universe (the Theory of Everything).
In String Theory, there are currently three accepted versions. All three versions describe matter as infinitely small vibrating strings of energy. Way smaller than atoms or any known subatomic particle. The most acceptable of the three String Theories allows for "11 other dimensions" and an infinite number of parallel universes. We live in one universe and can experience 4 dimensions (length, width, depth, time). Any attempt on my part to describe the other 7 dimensions would be as futile as the scientists who have attempted to explain them in their theories. They can't, but they need them for the math to work, and if you accept that the universe is mathematically balanced, they must exist.
My point is that if String Theory is correct, in alternative universes Grant lost. Grant was killed. Grant never joined the Army. Grant became dictator for life. Lee was a horse trader, Lincoln was a slave, and on and on and on. So, in some parallel universe, Lee won and I can afford to collect all the toy soldiers I want, and I want them all.
