The Living Force
As far as I could understand, time is not an independent dimension of X, Y, Z. The C's said that time does not exist, that it is an illusion. Well, maybe what we understand by time is an arrangement of gravity. What I want to say and referring to what is described in the video, the real protagonist is the movement and that time results in an erroneous perception. In summary, the idea that is presented to me is that perhaps it is that gravity by its property of being both contractile and dispersant, which causes the movement of everything that exists in a variety of degrees of strength. Therefore the use of knowledge takes away the weight of things and produces light. Making use of knowledge indicates that you have to move, perform movements. And what moves, what always moves is the space and the objects that compose it.
In some lattice spacetime models, you can think of gravity as being links and matter as being at the vertices thus in effect gravity would be a timelike movement from one vertex/state to another. You would still have time along with space as coordinates but your timelike "gravity" movement could be time traveling back to a smaller time coordinate. It kind of still takes time to travel backwards in time. It would probably take something like Ark's conformal gravity to allow time travel-like movement. The idea of time as an illusion is kind of the idea that the past and future in various versions are always there already, you just have to move to them.
