This paper introduces a new cosmological model founded on the concept of vertical time, speculating a temporally organized multiverse where each universe gives rise to a successive successor. Parallel universes in such an arrangement do not coexist but appear on successive layers organized by a meta-temporal dimension of extra structure. The model unites Roger Penrose's Conformal Cyclic Cosmology (CCC) and Lee Smolin's Cosmological Natural Selection (CNS) theory, introducing black hole singularities as the source of new universes. Vertical time is then cosmic genealogy: the collapse of each parent universe begets descendant universes. The model stands opposed to standard linear cosmologies by offering a cyclical reinterpretation of time and entropy so that extreme events (e.g., cosmological crunches) rebalance thermodynamic conditions between universes. Even speculatively, the model offers potential observational signatures, e.g., anomalous cosmic microwave background patterns or distinctive primordial gravitational wave signatures. Philosophically, vertical time is really a synonym for traditional themes of eternal recurrence, marrying metaphysical issues of origin to modern physics. Deep issues still persist, such as the mechanism of causal inheritance between event horizons and the possible infinite regress of cosmic generations. By imagining the multiverse as a continuous temporal continuum of cosmic ages, the new entity subverts classical theory and invites us to further investigate the nature of time, causality, and cosmic evolution.
