I think the refutation is that the computer would have to keep track of itself, and this is for some reason impossible.frezik wrote:The second law is a strange exception to the usual laws, in that it's based on probability rather than absolutes. For instance, it is theoretically possible for all the oxygen molocules in the room to organize themselves into one little corner. Such a room would have "broken" the second law by being more organized, but it's so unlikely to happen that we discount it entirely.
I suspect that a universe where the second law could be violated would have some frelled up laws of probability to go with it.
You can also refute it with QM. In QM, not only is the future position and momentum of a particle indeterminate but the past trajectory is as well
