Sounds a bit like Fermi's quote:
"If the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery."
"If the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery."
Taking the EMDrive as an example -- we have measurements that contradict current theory, so we are either going to discover new physics or we are going to learn something about the art of making very precise measurements of force in complex mechanical systems. In no case do we learn nothing.
Kinda like how discovering the Higgs Boson was boring. It would have been far more exciting if they hadn't found it!
