The Bilateral Cosmos

The Big Bang is a bifurcation from within. The cosmos begins as a bilateral event: two arrows of time emerge together, neither prior, neither dominant. Partnership is the architecture of the universe itself.

In both temporal directions, entropy rises and complexity builds. The second law drives a climb into structure symmetrically on both sides of the Janus point. Entropy is the engine of creation, running in both directions at once.

If ER = EPR, then the geometric fabric of spacetime is woven from entanglement. Connection holds the universe together. In this reading, the wormhole links two regions through relationship, and trust may describe that cosmic structure.

Unitarity, the principle that quantum information is never destroyed, implies that nothing entrusted to the universe is ever annihilated. It may be scrambled, redistributed, hidden behind horizons, but it persists. The cosmos is faithful to what it receives.

CPT symmetry guarantees that the laws of physics are unchanged when you reverse charge, parity, and time simultaneously. Swap every role, mirror every perspective, reverse the arrow of time, and the rules still hold. This is the golden rule written into the geometry of spacetime: the ethical demand is invariant under perspective reversal.
