In our new picture of physics, the three-dimensional structure of the universe arises through composition of one-dimensional realities, each dimension independently capable of supporting physics. As mentioned earlier, this implies three time dimensions.
In the beginning there is nothing. Through some unspecified process, field oscillations form in the vacuum. As there is no matter at this time, this may be an energy-free process. Each oscillation is constituted of a one-dimensional spacetime: a dimension of limited length, persisting for a duration, over which a field oscillates. It may be that the endpoints of the dimension are charges (this figures in particle genesis below).
The dimensions compose themselves into volumes. As the time dimensions are composed, an as-yet unspecified dynamical principle causes them to form a hierarchy of stiffness: time is a measure of the resistance of a spatial dimension to propagation of "energy." Therefore, some dimensions propagate more readily than others.
Assuming that spatial composition occurs in random "bubbles" that merge as space is formed, topological inconsistencies (in either the temporal or spatial structure) must be resolved as the boundaries merge. At some scale, the energy associated with resolution of the topological inconsistencies is less than the potential energy stored in the spatial matrix. Defects are then squeezed to a geometrically isolated location, which become quasars on the rebound, and then clusters of supermassive black holes. Cosmogenesis occurs as the black holes release the energy of composition as self-propagating spatial and temporal defects - fermions.
This neatly explains the galactic "bubbles" in the deep field survey.
