Entropy is not a conserved physical property and neither is information. Entropy doesn't need a source, it can be created from nothing, but once created Entropy can't be destroyed, even a Black Hole can't destroy it. A Black Hole has an astronomical number of nterior of microstates but just 3 numbers are enough to perfectly describe its external macrostate, if you know the Black Holes's mass spin and electrical charge you know all the is to know about it. >> >> >> Before you burned the diamond only one microstate would produce the same >> macrostate, after the burn a astronomical number would. > > > > > > Sure, but it wasn't a closed system. > The oxygen, the diamond, and the battery powering the LASER are a closed system, and every one of those components has increased in entropy and thus the entire system has too, and that's exactly what the second law of thermodynamics says it should do.
