COSMIC
ISOLATION

Black holes isolate inward. Cosmic Isolation isolates outward.

Standard cosmology traces the universe back to a singularity — a region where density and curvature become infinite and known physical laws lose predictive meaning. Inflationary cosmology resolves several large-scale puzzles, including the horizon and flatness problems, but relies on finely tuned scalar fields and uncertain mechanisms. White holes provide a formal time-reversal analogy to black holes and the Big Bang, yet remain mathematically unstable and lack observational support or a natural formation mechanism.

The central issue remains unresolved: whether the universe truly emerged from a physical singularity, or whether singularities instead signal the limits of current theoretical frameworks.

The proposal: Cosmic Isolation suggests that the observable universe originated not from an infinitesimal singular point, but from a causal detachment event within a larger spacetime structure. In this framework, a finite domain of spacetime undergoes runaway expansion until it becomes causally disconnected from its parent manifold — forming a self-contained universe with its own internal arrow of time.

The geometric intuition is clean: black holes isolate inward through gravitational collapse. Cosmic Isolation isolates outward through accelerated expansion. Rather than interpreting the Big Bang as the creation of spacetime from nothing, the framework interprets it as a geometric transition between connected and causally isolated domains. Collapse ends histories. Isolation begins them.

If mathematically consistent, the framework may offer alternative perspectives on the large-scale uniformity of the CMB, the horizon and flatness problems, and the origin of low initial entropy. The paper references ideas associated with Roger Penrose, Stephen Hawking, Leonard Susskind, and observational data from the Planck Collaboration.

The Conversations That Followed

The work was first shared in person with Prof. Harish Chandra Verma (Padma Shri), former Professor in the Department of Physics at IIT Kanpur, who encouraged its continuation. Through his reference, the paper was discussed with Prof. Pankaj Jain (Emeritus Fellow, Department of Space, Planetary & Astronomical Sciences & Engineering, IIT Kanpur), whose feedback emphasised that the idea is conceptually interesting but requires significantly stronger mathematical foundations for formal scientific evaluation.

The framework was also discussed in person with Dr. Tejpreet Kaur (Institute Postdoctoral Fellow, Department of SPASE, IIT Kanpur) during an extended conversation on the conceptual foundations of the proposal. These conversations did not validate the framework — they sharpened the problem. The path forward requires mathematically rigorous development of the causal detachment mechanism, and I am actively seeking academic collaboration with physics departments to pursue that next stage.
