- Generating appropriate initial conditions for the Universe is key to discussing cosmic evolution constructively. In standard cosmology the traditional approach assumes an early Universe that emerges from an infinite density, spacetime singularity. It then undergoes inflationary expansion, followed by a matter-creating reheat period. This approach produces results generally in good agreement with observations. However, to date it is not known how (or even whether) a true past-directed spacetime-singularity can generate a regular spacetime that becomes the observed Universe. It has previously been suggested that appropriate initial conditions should emerge naturally from existing physics rather than be set a priori. In this work we seek to generate initial conditions predicated on the Self-Regulating Cosmology (SRC) model recently presented [1]. In SRC, cosmic dynamics leads to a universe that also self-regenerates from one evolutionary cosmic phase or (hereafter) kalpa2 to another. Within each such kalpa the dynamics evolves between two disparate scales of horizons. The end of a kalpa and the beginning of the next interface through a phase transition. The interface of the two phases sets up the phase initial conditions of the emerging phase. These include: a natural time-reset, and energy, volume (space) and entropy conditions. The issue of whether (or not) the early Universe undergoes inflation becomes naturally self-manifest in this treatment. In the context of the SRC model, we discuss the Initial Entropy Problem (IEP). Lastly, we highlight on current observations of over-mature (galaxy and black-hole) structures at high redshifts, by JWST.
