The tl;dr is that some scientists investigate some fringe technologies that violate the laws of physics and based on some preliminary studies it looks like there could be something. However it's still vastly more likely that the studies are flawed than that we'll have to rewrite the laws of physics.
I disagree. Even if this actually turns out to be producing thrust due to a reason other than thermal expansion, ablating material, interaction with the Earth's magnetic field, etc., that doesn't mean fundamental laws are wrong. It depends on why it's happening, right? There are...I can't even call them theories...musings that this may simply be an effect which we aren't aware of, but doesn't violate conservation of momentum.
We are so far away from being able to explain why, however, since we first need to determine if this is real and repeatable. I hope that other credible researchers attempt to replicate this.
I had the impression that the laws of physics are seldom rewritten, more of a fix here, another one there. OTOH, one can hardly say that it violates such laws while we don't know how it works.
Not really, because in this case it violates fundamental laws of physics, thereby the probability that the experiment has a source of error unaccounted for is extremely high.
