It also answers not much, just changes the question. There's no known reason for all the matter to be over here, where we are, and all of the antimatter to be way over _there_ outside of the observable universe. If anything that seems much less likely than there just being other imbalances in which gets created (or which survives over time, etc.). The universe would have to have preferred absolute directions in which to throw different types of matter/antimatter? That'd be very strange indeed, based on what we know.

>we are never going to be affected by this fact (since it's in a part of the universe from which information may never reach us).

For curiosity's sake: Wouldn't something like quantum mechanics defy that argument?
