> But anything observable in the world of reasonable energies (up to whatever modern colliders achieve) can be predicted with existing theories. This is classic "world is flat" / geocentric argument. Breakthroughs are impossible to predict but can't happen if we give up. Edit: > If we discover something that only happens at astronomically high energies, would it really be that useful? We don't know. World being round turned out to be pretty useful.
