In the case of gravitational waves, back in the 1970s, hundreds of independent research groups constructed simple devices to measure them and they all compared their results. Each research group thought that it had measured gravitational waves, but when the results were combined, they all had to conclude that no one had been measuring gravitational waves. They had all been measuring different sources of noise.

A hundred other researchers say, “We have used the same device to measure gravitational waves and found that it is too sensitive to local sources of noise to be able to conclude that anything it measures is cosmic in origin.”
