Not disproving the current theory is not the only benefit that can happen: - You have to kick the tyres now and again. Sparingly perhaps, but you have to do it

Not disproving the current theory is not the only benefit that can happen: - You have to kick the tyres now and again. Sparingly perhaps, but you have to do it. - A lot of what people learn is NOT whether this is a new form of propulsion. It's things like "how do we make a really really sensitive propulsion measurement system?" along with with come more mundane things like teaching the grad students how to code. If we only exercise when we're sure something exciting will happen, we won't exercise.
