I didn't mean direction. What you define here, backwards-static-forward are simply states of motion, using Antonio's terminology, degrees of freedom. But a whole dimension always has 2 degrees of freedom. I mean time, as we know it and see it now, is 1 dimension, for you can go past and future. Like height: up and down, like width: one side or the other, like depth: forward or backwards. But what I meant is if there are two other time dimensions? Maybe yes. And we always percieve the most obvious, but as in appearance all dimensions are the same (I mean, if you are lying on the floor, for you height is depth, and width is height...), then the time dimensions look like the same 1 dimension, but in reality in each case we choose the most appropiate. It's very har dto think about it, but it does have background.
