In this chapter, we are going to develop a novel cosmological model based on the outcome of the off-shell science we have explained so far. We begin our discussion with a brief reviewing of our studies summarized in the following subchapter 9.1 ([i]–[iv]). Since cosmology remains a vast, unknown frontier in the physical sciences, in dealing with mysterious cosmological problems, we adopt a simple and effective approach, the Occam’s razor principle. In line with studying the extended light field, we employ a couple of unique hypotheses proposed by Petit [12 in Sect. 7] and Penrose [1] called conformal cyclic cosmology (CCC). The first one is on the twin structure (matter and anti-matter) of the universe, while the second one is, as its name shows, on the cyclic temporal evolution of the universe. Since our new cosmological model can be regarded as a variant of CCC, we call it CCC of the second kind (CCC-2nd) and will be explained in subchapter 9.3. According to CCC-2nd, as in the case of the creation and annihilation of the matter and antimatter pair, the twin universes as metric space-time are birthed by a certain kind of SCSB of a light field with null distance ( \(ds^{2} = 0\) ). The twin universes thus created are divided by an event horizon intrinsically embedded in the de Sitter space structure caused by the most dominant component of dark energy. Eons later, the twins meet at the event horizon to return to the original light field, and this cycle repeats forever. In our cosmological hypothesis, the flatness, isotropy, and horizon problems are resolved, respectively, by the observed existence ratio of dark energy to matter, the Weyl curvature hypothesis proposed by Penrose [6 in Sect. 8], and the existence of a superluminous off-shell electromagnetic field.
