The universe is cube shaped ok now, i will just comment that these cubes aren't really energy, they can't move or be destroyed, they are merely like a coordinate system that just happens to be cubic in shape. Like 3-dimensional pixels, where energy travels across them constantly, never actually being able to stay still on one cube. You can have a cube "light up" if you will, a certain way and stay that way, but this is only a result of energy constantly moving into and out of the cube creating a cycle, or equilibrium. We know this because energy is movement, and there cannot be true non-movement, except fot he cubes themselves, which by themselves, are not actually energy, and merely a coordinate system.
Interestingly enough, this coordinate system of universal cubes could be used to accurately determine distances in space, at least from cube to cube, as objects are made of energy and energy always moves a bit, always giving different readings of distance, therefore.
