Due to the complexity of this section, let us review the local expansion in space-time.

At first, we are used to imagine that light is scattered and radiates in space with the constant speed of light. However, as we discussed, light cone is an ideal representation of the expansion in the wrinkling epoch. Strain packages of electromagnetic field have geometrical deformations (curvature and torsion) that oscillate. Since, these deformations do not lock the expansion in that strain package, location of the strain package starts to diffuse and expand after the emission of that package.

Of course, the expansion meant here is not Hubble’s expansion. Hubble’s expansion is the wrinkled and self-collapsed state of the expansion. We have given the “growing tree” example, and we discussed the dissimilarity between Hubble’s expansion and the expansion the (flux) in Section 5.1. Simply, Hubble’s expansion stands for the growth of the overall size of the tree, and the expansion stands for the growth of that tree’s branches.

We can visualize a flash of light as a young sprout of our growing tree. In fact, a flash of light is a newborn space, which fundamentally expands in the wrinkling epoch, where the increase in the overall circumference’s size of space is decelerated.

According to our discussions in previous chapters, constant and continuous expansion is the most basic act of Nature. Hence, the local expansion of light cone is integrated into the expansion, and it is a function of the expansion, but it is not an individual occurrence. In fact, constancy of speed of light is a result of the wholeness in the expansion, and it represents the path of the expansion in the wrinkling epoch of Nature, analogously to the growth of tree branches.

On the other hand, the expansion means that locations itself expand, in contrast with the growing of a tree’s branches, which occurs in a static volume. Naturally, a strain package cannot prefer a specific location to be in expanded locations, because expanding locations are equivalent, and the expansion is omnidirectional. Hence, locations, where the strain package can be, expand by time.
