I think the best sentence is this:
"The theoretical expectation is that you don't measure anything. Now you're measuring something, and you can learn extremely much on this hunt for the error."
"The theoretical expectation is that you don't measure anything. Now you're measuring something, and you can learn extremely much on this hunt for the error."
"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!
