As far as I know, the EmDrive is still considered controversial and it is not certain whether and how it works. It is interesting because it could cause a revolution to how we view impulse, so it might be a colossal thing just as much as it might be complete nonsense. So I think the comparison is disingenous.
- gus_massa 10y agoIt's difficult to explain in a short comment, but the Em-drive is as controversial as the yeti. If it were true, then it breaks the current laws of physics. In particular the conservation of momentum and energy. There are some bogus explanations that try to make it compatible with the current laws of Physics, but they are nonsense. Breaking the current laws of Physics is not bad if you have a good experiment. The problem is that they are measuring a very small force that is very close to the experimental error. And there are many other forces that are difficult to calculate and may explain the force they are measuring.
