THE CONJECTURE. “Let us call this the Symmetrical Time Hypothesis (STH). Symmetry suggests that after reversing time direction (T), all properties of each universe are identical, including rate of expansion of space-time. Charge (C) and parity (P) will appear reversed from the other universe’s standpoint, so the two universes will be CPT invariant.”
