>Shawyer has often been dismissed by the research establishment for not having peer-reviewed scientific publications, but White and Tajmar have impeccable credentials that put them beyond cheap dismissal and scorn. Physics is an experimental science, and the fact that the EM Drive works is confirmed in the lab. "This is the first time that someone with a well-equipped lab and a strong background in tracking experimental error has been involved, rather than engineers who may be unconsciously influenced by a desire to see it work," notes Wired referring to Tajmar's work.

>Hacked has obtained a copy of Tajmar's Propulsion and Energy Forum paper, co-authored by G. Fiedler.

>"Our measurements reveal thrusts as expected from previous claims after carefully studying thermal and electromagnetic interferences," note the researchers. "If true, this could certainly revolutionize space travel."

>"Additional tests need to be carried out to study the magnetic interaction of the power feeding lines used for the liquid metal contacts," conclude the researchers. "Nevertheless, we do observe thrusts close to the magnitude of the actual predictions after eliminating many possible error sources that should warrant further investigation into the phenomena. Next steps include better magnetic shielding, further vacuum tests and improved EMDrive models with higher Q factors and electronics that allow tuning for optimal operation."


So the EM Drive works in vacuum... aaaaand it looks like it might actually work as advertised.

Well, it's not everyday you get to violate Newtonian physics. I was kinda suspecting this would fizzle out into vaporware or something (still could, as they say in the article they still have further testing to do before it's confirmed 100%), but... hot damn.

  It's actually happening?

It's real?
>> No. 7248 ID: 06a0fb
no. If you click in and read the actual published abstract, it only says that after eliminating many sources of error from the originally used testing methodology, the predicted and observed thrusts are very close, such that further investigation is warranted.

Thrusts so observed during this round of testing were ~
>=/-20 microNewtons

which is roughly 0.00014466 pound-feet/second of acceleration right now.

It bugs me that people are saying that, there is still an equal and opposite reaction, it's just not matter getting thrown away at high speeds.

Well, we don't actually understand how it works. Current theory behind it is "quantum particles" or something if I recall directly (one of the guys behind it likened it to being a submarine in water, and the EM Drive moving the "water" like a sub's propellers - except instead of water in this instance, it's shit we don't understand very well), but the problem is that the EM Drives seem to operate and provide thrust even when they shouldn't. Guido Fetta's design has slits in it... and the damn thing still provides thrust even when it's closed. This would be like having an airliner with the jet engines inside the cabin, underwater, somehow providing forward thrust. It shouldn't fucking work according to what we know.

Correct. I'd say optimism is warranted, but it should be cautious optimism. It could still be some sort of interference or error in reading, but... it's shocking that it's held up thus far. Promising, but we haven't proven it entirely.

As far as the thrust produced, the thing is that is scales well. So if it does actually work... yes, you can crank up the magnitude and get usable results.

If it works, that is.
>> No. 7255 ID: e7f332
I wouldn't even say optimism, just further study.

Remember kids, if your current understanding of science is appearing to be violated by something occurring in reality, it is a distinct possibility that your understanding of said science is incomplete or has a false assumption somewhere.

Contradictions do not exist, so either we are observing it wrong or our understanding of reality is wrong. We'll figure it out.

>Contradictions do not exist, so either we are observing it wrong or our understanding of reality is wrong.

This. The part I'm optimistic on is that we were not entirely right about the science and that this works, and we just didn't understand how at first.

But just like the faster-than-light neutrino incident from a couple of years ago, it could end up being complete bunk and we missed something that was interfering with our results. I hope not, but...
>> No. 7257 ID: f2c4ed

I like this. A test produced results, now a more precise test has produced very similar results. How it works, nobody's sure, and perhaps it's still an error, but this is results driving experiments and theories, not theories and agendas driving experiments (and sometimes results).

There's more going on that just a tiny bit of thrust.

>NASA scientists working on a project called EmDrive have accidentally stumbled upon something that will send science fiction junkies into a frenzy. The possibility of a real-life warp drive has been placed on the table thanks to readings that indicate the EmDrive’s resonance chamber sent beams traveling faster than the speed of light, which would be considered warp speed.

tl;dr - A laser beam shot through the EM field inside the drive to measure shit accidentally violated relativity and left before it got there.

If we've discovered a mechanic by which an EM field can warp space? Say hello to the electro-gravitic unicorn of the 1950s, only this time we caught a live one.

Looks interesting to say the least. Hope it don't turn into another cold-fusion fiasco.

>> No. 7262 ID: f2c4ed
I'm wondering if that's what been going on, and why the "effect" in question lasts for a bit (no article has been specific) after the device is turned off. If someone accidentally stumbled into a gravity warping mechanic, then it would fit the following point, which seems to be what people are hanging up on:

It's pushing off something solid without using matter. A literal, miniscule warp in spacetime, pushing rather than pulling, like a gravity bump instead of a well. Which is, as far as I know, theoretically possible.

I'm getting excited, the more this phenomenon shows up, and the less easily it's explained, the more likely it is that it's Something New.

I'm not a physicist, but could it have something to do with plasmon reactions? It might not be truly reactionless
>> No. 7267 ID: de9789
>It might not be truly reactionless

Well, that's the thing that has the scientific community's panties up in a bunch. From what I can tell, there's a bit debate over whether it is meeting the definition of "reactionless".

EMdrive proponents say that the drive is actually not reactionless, and is simply interacting with a medium that we don't understand (like quantum particles) and it's not reactionless, it just seems that way from our lack of understanding.

Skeptics claim that the drive, if it were to function, would be reactionless and that's why it does not actually work. And that something is just interfering with test results that will eventually be fleshed out.

Well either way if it's real this is the most efficient space propulsion ever devised... thanks Brits!

Shit they also invented that earth-orbit jet engine SSTO thing right? They're really on a roll

Unfortunately, despite their apparent brilliance the British space industry is perpetually starved of funding.

I thought pretty much everybody came down on the side of this thing working on quantum tunneling?
