I Just want to know; what do people think time is; a Vector or a Scalar?
Post with your opinion, I want to see what most people think about this.
Ok, to avoid confusion:
A Scalar is a quantity that has only magnitude(size); for example: Distance, Speed, Mass.
A Vector is a quantity that has magnitude(size) and Direction(that it acts in); for example: Displacement, Velocity, and Weight.
Well truth be told if you use the euclidian action (not to be confused with euclidian space) in the Feynman path integral formulation of quantum mechanics, then time is a complex variable (meaning it has real and imaginary terms) and from there you can easily see that we are in a Minkowski space, which is a 3+1 dimensional vector space. Hence time is a vector.
In fact, you can interpret solutions to the Dirac equation to mean that anti-particles such as a positron (anti-electron) is just a regular particle traveling backward in time. This led Feynman's thesis advisor, John Wheeler, to develop the one electron theory of the universe.
