NOW: A Theory of Convergence proposes that the universe is one thing with two opposite compositional sides — matter and antimatter — moving in opposite temporal directions from a fixed interior point called the conversion point. The present moment is identified as this conversion point. The framework offers physical mechanisms for dark matter, dark energy, gravity, consciousness, and panpsychism, and connects to CPT symmetry, the Wheeler-DeWitt equation, and Tegmark's Mathematical Universe Hypothesis.
