Primordial Transformative Scalar Field (PTSF): A Topological Eversion Model for Cosmological Origin

We propose a speculative but mathematically consistent cosmological framework in which black holes act as generative boundaries rather than terminal objects. The model introduces the Primordial Transformative Scalar Field (PTSF), an effective scalar degree of freedom that becomes dynamically relevant near Planckian density and mediates a non-singular transition between classical spacetime and a pre-geometric quantum-gravitational phase, preventing the formation of physical singularities. The quantum evolution through this transition region admits a continuation into a causally disconnected spacetime branch, interpreted as a child universe. We propose that this branching is mediated by a geometric eversion mechanism, in which the interior degrees of freedom of the collapsing black hole unfold into the exterior degrees of freedom of the emergent child spacetime — parametrized by an eversion parameter τ ∈ [0,1]. Kinematic consequences of this eversion are developed, including a geometric reinterpretation of late-time accelerated expansion and a qualitative account of the Hubble tension, consistent with recent SH0ES and TDCOSMO 2025 measurements. The framework preserves unitarity, provides a natural mechanism for cosmological recycling, and predicts observable consequences, including a mild enhancement of the late-time Integrated Sachs–Wolfe effect and a cumulative correction to the stochastic gravitational-wave background at millihertz frequencies. Order-of-magnitude estimates indicate the observed cosmological constant can be reproduced without fine-tuning. The recently discovered population of Little Red Dots (JWST) is identified as a potential class of observational tracers consistent with the framework. The model is falsifiable with forthcoming observations from JWST, LISA, Euclid, DESI, and the Rubin Observatory. This is presented as a theoretical sketch by an independent researcher, offered in the spirit of open scientific dialogue: not as a finished or peer-reviewed result, but as a structured, falsifiable proposal intended to invite critique, mathematical refinement, and engagement from the physics community.
