People in love do awful things, I'd rather the drive run on intolerance for bullshit.
Ah, the Shrike's just a big cuddle-bug, honest.  It's just also made out of sharp blades, razorwire, and long thorns.

I could totally dig becoming a Shrike.
Can I sig this?

So, um, the EM drive could in fact, be a dark matter drive?? http://www.forbes.com/sites/startswithabang/2016/11/30/could-dark-matter-be-powering-the-emdrive/#9b4eab11e539

It's a pretty wild idea, though I have no idea how they'd get any meaningful thrust out of it.

It works by torturing the souls of the dark matter people.

Ah, so we're no longer going with the working theory that the EM drive functions by draining rotational momentum from Isaac Newton's grave and translating it to linear momentum?

Given that the thrust of that is so miniscule, less than an ion drive even, it's hard to see how they could scale it up or give meaningful thrust. That depends on figuring out how the heck it works in the first place though.

To begin with, they could build a proper resonance cavity. The one they tested is built out of bolted-together scrap and literally made at someone's kitchen table. A lab-grade resonance cavity is carved out of a solid block of metal by a CNC machine to Space Shuttle tolerances.

Considering the EM Drive's effect seems to be based upon resonance somehow, making a proper cavity would increase the thrust.

I can't see forbes since they keep popping up their annoying little adblock nanny thing so I forbid every bit of the site pre-emptively, but I'm guessing if the power levels involved and a resonance chamber could accidentally provide evidence of dark matter, then professional scientists who actually do this sort of stuff for a living would probably have deliberately tried to do just that sort of experiment, and to date I haven't seen any blurbs about "dark matter detected directly" or anything alone those lines.

On the topic of dark matter being directly detected an MD the concept of dark matter drive:
Weren't we just talking about the paper on how dark matter is not per se a detectable atom, but rather a glue like force that holds everything together? Therefore, one could say this is a 'gravity drive', but once again that is mere labeling speculation. If it DOES work off dark matter, and they actually built an up to par EM drive, wouldn't it be working based off gravity alone? Since electromagnetism is what can be seen not only on our planet but as well as the rest of the universe, wouldn't my above conjecture make sense? Or no?

Also, the mere fact that they assembled it at a workshop table and it still produces thrust is a surprising factors considering it still gave thrust.

Hmmm, don't remember the gluematter thing. A force carrier with enough mass to produce the visual distortion seen in galaxy clusters would probably need a force to carry, and the more massive bosons are pretty impressive when you get them unbound, nuclear explosions and whatnot.

Last thing I heard, the NASA paper was bad, horrible methodology, just terrible, absolutely worthless. Sad!

Except in scientist speak instead of trump speak.

The NASA paper examining the methodology of the EM Drive paper was itself lacking in methodology?

I also saw an (the same probably) article saying that, I think it was on one of those gizmodo but for science type sites.

Personally my hunch is that in a few years they're going to be turning around and saying there's no such thing as dark matter, it was just a crutch to fill in some other blank they didn't know about. Dark matter is only needed because of assumptions about cosmic inflation which have been challenged by more recent theories.

Not holding my breath over the EM drive either. Saying the EM drive works because of dark matter might sound so ludicrous in a few years it will be viewed the way we view oxygen being thought of as "dephlogisticated air".
