Unifying physics theories with a single postulate

Abstract

Humans have developed mathematical theories to explain observed physical phenomena in nature. However, the links between these theories are not fully understood in 2024. Apparent incompatibilities between quantum mechanics and relativity, for instance, still exist. This paper proposes a comprehensive theory of the universe that includes gravitation, quantum mechanics, electromagnetism, special relativity, and general relativity. All of these theories are derived from the single postulate that the universe is a four-dimensional ball undergoing accelerating inflation, the surface of which is our three-dimensional world.
