Here's a discussion I'm hoping to start.
As you may be aware, time goes forward. A shocking thing to say I know- but the universe clearly prefers time going from past to future, some relativity implications non-withstanding. The interesting thing about it is that the laws of physics seem to not have this preference for the most part. Have time progress backwards in your equations and some interesting things happen but overall most of the laws still work just fine.
The only really big exception seems to be the Second Law of Thermodynamics. The famous "in a closed system, entropy tends to increase with time".
My thought is, what if this interpretation isn't the correct one? Or at least isn't the only valid one?
Picture if the proper interpretation is "systems are found either in or moving towards their most probable state". What qualifies as the most probable state may change depending on the direction time is progressing, but we certainly see the previous interpretation within that considering disorder is more probable then order- and with particle velocity vectors perfectly reversed if time's direction is reversed the previous state becomes the most probable- right?
Anyway- an admitted weakness with this idea is my equations use. The Boltzmann Equation of S = k ln W would hold, and if we differentiate both sides by energy we see.
Which admittedly I'm kind of stuck. It looks time independent too me, as W is the degeneracy of the micro-state within a macro-state.
Anyway, what I'm hoping to achieve is discussion. Ideally, with equations for or against depending on your view.
So, thoughts?

dS / dE = k d[ln W] / dE
1/kT = d[ln W] / dE
1/kT = d[ln W] / dE
