Well, they were mostly weirded out that it was the same hiss no matter where in the sky they pointed the horn, and indeed, that's pretty weird. It was non-obvious, and now we know why.
For the emdrive, the effect is so small that it's suggested that the next step is to launch a powerful satellite costing $100mm or more. Uh, really?
From your comment, you seem to be tangled up in results being "dismissed". That's not what's going on, when people make comments about extraordinary claims and extraordinary results. A tiny, hard to measure result is not an OH MY GOD THE THEORY IS WRONG result. It is likely an experimental error.
- StanislavPetrov 10y agoIts ironic that skeptics of the EM drive not only refuse to consider the actual, empirical evidence, but also oppose testing it in the only way that is beyond dispute.
- beevai142 10y agoIt has already been independently tested (TU Dresden, NWPU). They saw only noise.
- dzdt 10y agoA tiny satellite in low earth orbit is a stunt, not a platform for high precision physics measurements. For the satellite, there is atmosphere drag, magnetic fields, outgassing, etc, all probably bigger effects than the claimed drive effect! Earth bound labs have much greater control of variables, reproducability, possibility to measure related quantities, possibility to run variations on experiments. The reasons to do the satellite are (1) PR (2) wanting to NOT disprove the effect.
