A Bold New Vision of Reality: What if the structure of the universe is built from recursive shells of awareness, folding themselves into existence? A Note on Scientific Claims This book is not a peer-reviewed physics text, nor does it present finalized mathematical proofs. Shell Theory should not be read as established science, but as a provocative, thought-driven model born from a near-death experience and shaped by interdisciplinary reasoning. Its value lies in its vision, not its verification. Readers should approach this work not as a guaranteed physical theory, but as an ontological framework — a radical interpretation of consciousness, energy, and structure inspired by a lived encounter with the boundary of life itself. If you are buying this book for rigorous mathematics, confirmed physics, or consensus cosmology, this is not that book. But if you are seeking a bold, deeply original account that challenges assumptions, expands imagination, and reframes what an NDE can reveal about the architecture of reality, then Shell Theory offers exactly that. In Shell Theory , Miguel Figueroa Rivas — survivor, analyst, forensic thinker, and accidental cosmologist — presents one of the most audacious unified frameworks of the 21st century: a model of physics born not in a laboratory, but at the threshold of death. During a near-fatal neurological collapse, Miguel experienced something rarely described in scientific language: the dissolution of the personal self into a larger, ordered, recursive geometry — a conscious structure that felt older than spacetime itself. Unlike mystical accounts, he returned determined to translate that encounter into mechanism, math, and coherent scientific principles. A sweeping, 400 page framework blending theoretical physics, cosmology, trauma science, recursion mathematics, and consciousness studies into a single, testable ontology of reality. According to Shell Theory, reality is not composed of particles or fields, but shells — energy-retaining membranes formed by resistance to enthalpy flow. These shells scale from quantum nodes to black holes to the entire universe itself. They store memory, generate spacetime curvature, and produce what we call matter, time, identity, and even mind. A Witness Statement Written as Physics Refusing both mystical vagueness and scientific gatekeeping, Miguel offers a rare hybrid: a first-hand witness account of consciousness beyond the body, followed by a rigorous reconstruction of its physical implications. Using principles from thermodynamics, geometry, fractal recursion, and quantum field logic, he develops a non-singular cosmology — one that eliminates infinities, unifies forces, and predicts specific measurable signatures in cosmological and gravitational-wave data. Unlike many modern “theories of everything,” Shell Theory does not hide behind elegance. It makes clear, falsifiable predictions about: Fractal scaling in cosmic structure - Echo signatures in gravitational wave ringdowns - Non-singular black hole interiors - Neural coherence during clinically impossible states - The cosmological constant as membrane thinning - The cyclical collapse and rebirth of universal shells This is not armchair metaphysics. It is a challenge to physics itself. If even 5% of Shell Theory is correct, physics, cosmology, and consciousness science will never look the same again.
