According to the second law of thermodynamics, entropy of an isolated system goes on increasing until it is in equilibrium. We often say that a consequence of this is that the entropy of the universe increases in any truly irreversible process. Now that means that the universe is in non-equilibrium. Assuming the universe to be an isolated system, it is intriguing as to why it should be in non-equilibrium? Hadn't the universe achieved equilibrium before the Big Bang? If the Big bang was totally an internal process, then the entropy couldn't have changed due to that. To cut long story short I am wondering as to why the universe is out of equilibrium? In terms of device theory the universe seems to be like a device connected only to source but no drain and yet far from equilibrium.
NB: I have little knowledge of cosmology. This might be a silly question. Enlighten me. [:)]

Entropy of an isolated system always increases.
