And that's not necessarily a problem. After all, we can measure things with insane accuracy (LIGO, atto/femto-second laser pulses, neutrino detectors, etc), our theories about the accessible energi regimes are quite good (14+ digits for QED - quantum electro dynamics).
At some point it's no wonder we need bigger microscopes to see deeper into reality.
Sure, were someone just come up with an even better theory that can be tested easily, that would be great too, but since we have no recipe for that, but we have quite a few for building bigger experiments, that's what most of the particle physicists advocate.
Yes. The problem is that ruling out is all that's happening. Not one has had an implication about lower energy ranges that has turned out to be right.
