So the fact that our universe is interesting has a threefold explanation: The principle of driven self-organization acts over a myriad of subsystems and scales, from the molecular to the galactic, evolving them to states of ever increasing complexity. The engines driving that process are the stars, which exist because of a combination of the fine tuning of the fundamental laws and the anti-thermodynamic nature of gravity. But these forces can produce a universe filled with stars and galaxies only if the initial conditions of the universe are strongly time-asymmetric.
