Is time really the 4th Dimension?
Assuming that we have free will, how could time be considered a 4th dimension? A dimension could be defined as a motion in the positive or negative direction (eg. +x and -x). If we have free will, can be doing different things at the same point in time.. For eg. I am sitting in my room at time t=t, at t=t+1, I could either be studying (in one universe) or I could be watching a movie (in another). Does the thought of mind change the time we live in or time itself is non linear and can explode into infinite different directions to accommodate the chaos we live in?
