In my model [a derivation I have based on forcing a "no information" condition on the Everything] space in any evolving universe is a collection of discrete points.
In a universe like ours these points can move about inside a given region within which they are the only point. These regions can be arranged in a geometric pattern like a grid. The universe would have some rules about the spacing of neighbor points and consequently where the point currently in question will be located within its region at the next state of that universe. This is rather like a cellular automaton but in the model it is subject to external true noise in various ways. In the right kinds of grid structure local oscillations could look like what we currently call subatomic particles. Our universe may have a face centered cubic grid [as a ground state grid] since this may have some low level oscillations that have a one to one correspondence with the known subatomic particles. These local oscillations can relocate in the grid but individual points may not. Superimposed on these local small scale oscillations could be large scale oscillations that resemble what is being called a weakly interacting cold dark matter. Just about the only manifestation of these large scale oscillations I can currently think of is of a gravitational type. I will submit a joining post a little later this week since I believe it is an excellent idea. Hal
