What would be the correct equation(s) to draw on a sandwich board to be worn that prophesies doom, gloom, and the heat death of the universe?

dS/dt > 0 or

lim(S) = inf

Not positive about that second one (the limit might approach a finite value), but limits always seemed much more apocalyptic to me.

Any of the myriad variations of the Anti-Life Equation

Also, just to make sure your signage is spelled right, it's "nigh" not "neigh." Unless you're working on some sort of Four Horsemen pun, in which case, good job.

ΩΛ = 0.728 [1]

The Clausius Theorem would be pretty good--basically it's the equation version of the Second Law of Thermodynamics.

If you want to be more definitive in your prophecy of heat death, use the strict inequality version of the Theorem, which applies to irreversible processes (ie, use < rather than <=).
