The predictions are based on what we know is out there, and how we would expect it all to react with us simultaneously. So as long as we have it exactly understood and haven't missed anything whatsoever, then yes, it would be therefore falsified. But we can't make such a claim.

I haven't really seen science work that way, since it isn't all that often we base our expectations solely on things we can completely account for. Science necessitates a certain amount of calculated projection. Theories are adjusted as new details are discovered, and only fools entertain themselves by resisting the bigger leaps needed to make actual discoveries.
