Not everyone agrees with this law. I am not a physicist but as far as I
know it only holds for closd sytems. It has not been show to be true for
open systems. See for example Price in Time's Arrow (Oxford, 1996). Page
7 in the Introduction: "Why was entropy low in the past? The chapter (2)
concludes with adiscussionas to what it is that really needs to be
explained about the assymetry of thermodynamics." See page 262 as well,
where chapter two is condensed.
