I'm not interested in explaining something so obvious. dqups1 got it immediately. I'm sure some other people will too.

That's better. You're making sure you understand what I'm saying before dismissing it.

Time is a term describing motion. A specific type of motion. I'm talking about temporal motion. Motion from one moment to the next. Time doesn't move. We don't move through time. We time. Time is not a dimension.

Call what a temporal dimension?

I said we 'move' through the spatial dimension and we 'time' through the temporal dimension. Did I say a move is a dimension? The temporal dimension is the time scape through which we time. Time is a verb.

Understand?

I never said time is a dimension. That's the standard model. Please re-read my answer.

Gravity, as far as I can tell, affects our temporal velocity. Even though we aren't moving when we are on the ground, we would be moving at a certain spatial velocity if the ground wasn't preventing us. Think of it as potential spatial velocity. Stronger gravity, slower temporal velocity.

Well our temporal velocity isn't constant and the spatial dimension has 3 plains. The temporal dimension only has one. As for why we only time in one direction, I assume it has it's origin in the Big Bang. There is no resistance to out forwards momentum and no way to change direction.
