Hi Stipes,

I read a book called "Stephen Hawking's Universe." And it stated that at the beginning of our universe, the big bang explosion created both matter and anti-matter.
Oh yes, anyone can STATE these kind of things, but I don't think anyone will be convinced by such a statement, as I don't think anyone will be convinced by this one either:
I read a book called the "Bible". And it stated that at the beginning of our universe, God created matter.
I don't want to be annoying, but my point is that anyone can make these statements. I would like to know why a statement should be true.

I am sorry I am a different person and use different words.
That's all right. It's not that my words are better, it's just important for a discussion that we know what the other means by certain words. A thermodynamic system is different from a chemical system in the sense that the first one is more general. The first one could also include radiation, magnetic systems etc. I really didn't understand the thing about the theologians, but I understand now that you meant something like theorists. This makes sense to me, so I'm glad you described what you meant.

Some guy proved when you reach this point, everything that we know of about physics do not apply.
I know. That was me.
The point is, that because our physics does not apply at that time, we can't say anything about the universe at that time. The first statement above is thus equally true as the second statement, untill we find a new theory that will be able to tell us what happened.

And if you say a crystal forming is an increase in entropy, then you are wrong.
You are right, I wasn't precise enough. What I meant to say was not that the entropy of the crystal increased, but the entropy of the system increased. If we consider the system as the chemical (at first liquid and finally a crystal) plus its surrounding environment, then the entropy of the system increased, while the entropy of the chemical decreased, because the increase of the entropy of the environment was larger than the decrease of entropy in the crystal and the entropy is an additive property. (This means that the entropy of the system is equal to the entropy of its components) So, I hope I put that right.
