Aether and reality concept paper

Abstract— The forces of magnetism, electricity, and gravity emanate from a fundamental, universal field that saturates the cosmos, forming the essence of reality. Within this field, swirling motions generate magnetic fields, while dynamic fluctuations create electric fields. Gravitational fields emerge from either compression or divergence within this foundational field. When translated into mathematical expressions, these relationships elucidate how electric and magnetic fields can be mani...
