No, because matter and energy are two sides of the same coin, and the 2LT applies equally. Of course, there are some subtleties concerning precisely which formulation of the 2LT one is employing, whether from thermodynamics or from statistical mechanics, but in most respects they are indistinguishable, which is precisely why popular science writers always conflate entropy with disorder, erroneously, I might add. Basically, matter is bound energy, and as in all things, energy seeks equilibrium, or the lowest energy state. In statistical mechanics, this is equated with disorder, because a disordered state is vastly more probable than an ordered one, which is why, if you throw the pages of an unbound book in the air, it will pretty much always land in a configuration in which the pages are not in order. Analogous effects also apply in thermodynamics. This is why disorder can only be described as an analogy for entropy, not entropy itself. As far as we can tell, all macroscopic entities are subject to entropy.
: you yourself have stated that you believe the Universe has always existed
I would hope that my statements have been more subtle than that, and I have certainly never expressed anything that could be called 'belief' with regard to this. What I have always said is that any categorical conclusions regarding the pre-Planck cosmos are premature, because the data support no conclusions as yet.
I agree but does this not violate the Second Law though.
That's a thorny problem, and indeed all the models for the pre-Planck cosmos currently on the table suffer from this niggle. There are some proposed solutions, but they are less than robust at the moment. Roger Penrose, for example, proposes that in many respects zero entropy and infinite entropy are actually indistinguishable, and can be treated as equivalent. The reasoning behind this is pretty esoteric, and I don't fully understand it myself, but there it is. Other proposals include a universe on the other side of the bang in which the 2LT is reversed, so that entropy actually decreases as it approaches the bang, and then increases on this side of it.
Maybe you could start a thread to explain this in more detail as I my self could certainly do with a more comprehensive explanation of all this
That might be a good idea. I had always wanted to expand on my essay on entropy to make it somewhat more comprehensive, and to have more detailed discussion with some of the physics bods here. I'll give it some thought.
