What if time didn’t move in a straight line in a single thermodynamically bound direction of increasing entropy, but bounced around just like rays of light?
Do we have a free will when we make a decision with time travel? Is the past fixed, and the future a set fate or destiny? The linear model of time doesn’t account that knowledge of the future affects the past, when even logic would suggest that is so. Alternative (multidimensional) models, such as those given by quantum mechanics would perform better. The future is yours. So is your history!
