Is it possible for maximum entropy to decrease?

[zeromodz]

Say in the far future when the universe achieves maximum entropy and all energy is rendered useless. Is it possible under ANY circumstances given all the time it needs to reverse entropy? I don't care about probability, does it break any laws in order of total reversibility of entropy turning into useful energy?

[Naty1]

very,very,very unlikely.

[zeromodz]

So your saying its possible, excluding probability?

[cesiumfrog]

Possible, nay, inevitable.
