"The results of NASA's tests on the 'impossible' EM Drive have been leaked, and they reveal that the controversial propulsion system really does work, and is capable of generating impressive thrust in a vacuum, even after error measurements have been accounted for.
The EM Drive has made headlines over the past year, because it offers the incredible possibility of a fuel-free propulsion system that could potentially get us to Mars in just 70 days. But there's one major problem: according to the current laws of physics, it shouldn't work."
Leaked Nasa Paper
So this means either the paper is wrong or our current understanding of physics is wrong.
Assuming our understanding of physics is wrong,
where do you think the correction ought to be?
