The 2nd law of thermodynamics refers to closed systems.
1. If we imagine a universe of infinite extent but where only one object exists that emits e/m waves, is that a closed system?
2. If we imagine a universe where only two asteroids exist and are orbiting each other, and a machine between them converts their gravitational energy into e/m waves that are emitted to space, does this system have zero increase in entropy?
3. If life on the asteroids absorbs some of the e/m waves and begins to add structure to the asteroids, is the entropy decrease due to life negligible compared to the entropy increase due to e/m waves partly turning to heat?
