Between all of the pointless social narcissism platforms and SJW Bs this is enlightening news. I am excited to see what discoveries will be made.
From my observation of the various participantsm, there's a distresingly large correlation between people who love the term "SJW" (who I've noted from, er, say, other threads) and people who seem to lack skepticism over this piece of obvious total bunk.
Seriously, this "engine" is either one of the greatest discoveries of modern physics (see the discussions around symmetry of laws and Noether's theorem), or it's bull. Given it was mathematically "proven" to work by the laws that have conservation of momentum baked in at a fundemental level, I'm inclined to say it's not right. When that maths was further shown to be wrong the exact same drive was "proven" to work not by magic (incorrect) relativity woo, but by magic (and I'm sure incorrect) virtual particle woo.
The maths is more complicated, and that will in time be demonstrated incorrect, if anyone bothers. In the mean time, it will continue to produce experimental results well under the noise floor.
Incidentily, that's exactly how the people above love to argue. Hammer loudly on a point until it's disproven, then at that stage, move on to the next, harder to disprove one, and keep hammering on that. So, it's not surprising that this argument appeals to those folks.
However, in physics, you can always set up the experiment again from scratch, so no matter how many dubious "proofs" are done, the experiemnts will never show this works.
