It's a piece of space tech that sounds almost too good to be true. The "reactionless" Electromagnetic Drive, or EmDrive for short, is an engine propelled solely by electromagnetic radiation confined in a microwave cavity. Such an engine would violate the law of conservation of momentum by generating mechanical action without exchanging matter. But since 2010, both the United States and China have been pouring serious resources into these seemingly impossible engines. And now China claims its made a key breakthrough.
Dr. Chen Yue, Director of Commercial Satellite Technology for the China Academy of Space Technology (CAST) announced on December 10, 2016 that not only has China successfully tested EmDrives technology in its laboratories, but that a proof-of-concept is currently undergoing zero-g testing in orbit (according to the International Business Times, this test is taking place on the Tiangong 2 space station).
I wish there was a forecast for when they expect results.

Looks like you have to rewrite your textbooks, sonny.
Reality doesn't care.
Juan Cruz
that line i quoted is twisting words and concepts into a state beyond recognition. it DOESN'T MEAN ANYTHING. if you aren't smart enough to read >popsci.com you shouldn't be posting here. if you aren't smart enough to understand when you're reading bullshit you should be focusing on your education.
Charles Ortiz
A fair step for based chinks, a gigantic fuck you to traditional western science dogma.
Joseph Cooper
what did they prove again? can you show me an article with their findings? or is an article written on popsci.com enough to persuade you something is truth?
Aaron Sanchez
I hope you are kidding, there is really no proof that they have done anything. And if they did do anything, it would have only been as a result of the usual chink tactics - copying the west.

WHY IS THE MEMEDRIVE SO GOOD
WHY DOES IT HURT MY BRAIN SO MUCH BUT I STILL CANT GET ENOUGH OF IT
I LITERALLY ORGASM AT THE THOUGHT OF HAVING LEARNED BULLSHIT FOR ALL THESE YEARS IN COLLEGE
I REGRET NOTHING
Michael Clark
But, China has never even been to space. They don't even have rocket technology.
Ethan Long
I'll wait till I have one in my car to start celebrating
Elijah Jones
Yeah I'm a retarded layman here but it seems like the reason it doesn't break the universe is that it requires a shitload of energy input to do anything, so it's not a fairy tale "perpetual" or "infinite" machine anyway
That said there's a benefit because you don't need to carry a ton of propellant to throw out your asshole to push you away but nevertheless you'd need a bitchin reactor
Zachary Powell
It requires a lot of energy to produce more kinetic energy than what you put into it. It's still free energy.
Angel Ortiz
The Chinese are on the forefront of submitting garbage to scientific journals, and continually pollute the peer review process (especially in the medical community) with a zerg rush that only China is capable of.
Wyatt Clark
That's only at relativistic velocities which is out of the scope of humans, and it's probably junk science anyway.
Jayden Phillips
>scientific cuck
Aiden White
>That's only at relativistic velocities which is out of the scope of humans Not true. The break-even velocity is given by
V = 2Rc/(1+R^2)
Where R is the ratio of thrust/power of emdrive to thrust/power of a photon rocket.
The fastest thing humans have ever created is the pair of Helios probes, which reached speeds of approximately 70km/s
To have that speed be the break even speed you would only need an R of 17131 or greater.
Now check out this page which gives experimental results of R
Now consider that the Helios probes were launched in the 70s, these are only "prototype" meme drives being tested, and the other tests are not far behind 17131.
So if the memedrive worked as advertised, it would mean easy free energy.

>the reason it doesn't break the universe is that it requires a shitload of energy input to do anything, so it's not a fairy tale "perpetual" or "infinite" machine anyway >That's only at relativistic velocities
Q factor of the resonance cavity is the best way of determining the efficiency of the EM drive in generating thrust, the higher the better on a linear scale. The current test machines have all operated at less than
Cooper Rivera
What gets me is not the memedrive. Its how many people are convinced ANY of our current models for anything in the universe are 'true'.
Kevin Perez
IF the Emdrive is "pushing off" of an unknown and normally very hard to detect something, then it's nothing magical at all,it's just using a fuel we normally can't interact with that's everywhere and it's not violating any thermodynamic laws.
Joseph Price
Hey guys quick poll. Are you buttblasted about meme drive?
Nah. Why would you be? Either it's nothing and the Chinese and Harold white look like dopey cunts, or it's real and we get to see the biggest shitstorm in physics of all time.
Oh and space will actually genuinely open up too. nuclear freighters will be cruising out to Europa within a decade if it works.

Because the guy who made it was too smug about it and because your degree becomes a joke
Elijah Garcia
Degrees are already jokes, this is just confirming what ive been saying all along.
Asher Taylor
On second look, they at least put in a null result from NWPU.
Cooper Gray
I don't even have a degree, I'm very conscious of how improbable this is, but the dreamer in me is kicking the shit out of the skeptic right now.
I'm just so tired of how mundane our universe is at the macro scale, all the fun things and awesome places are so far away as to take millennia of travel even at "fast" speed of a thousand miles per second. The weird what the fuck almost magical shit is all happening at a level too small for us to more than indirectly perceive. This is a macroscale miracle, it's like a giant sized quantum eraser or something, something that destroys intuitions and makes you stagger back in bewilderment at the weirdness of everything.
Listen to this stupid shit i'm typing, I'm so fucking ignorant about all of this, that's probably why i bother paying any attention to this dreck.
Easton Young

Aiden Baker
>Listen to this stupid shit i'm typing, I'm so fucking ignorant about all of this, that's probably why i bother paying any attention to this dreck. you're not wrong
it's like if there was a maths article published saying 2+2=4 is a lie and it actually is 5. there'd be people going mental saying we get free shit now because we can just put 2 doughnuts with 2 more 2 doughnuts and we suddenly get a free doughnut. infinite doughnuts for everyone!
well, I believe in free doughnuts just as much as I believe in the memedrive.
Landon Hall
This is a little different than that user, it might just be that thing is pushing off of something that's hard to detect, ie, it has thrust and is in fact 100% compatible with physics.
And need I remind all of you that in point of fact a "reactionless" drive IS possible if you could ever warp space a la an Alcubierre drive? This might even in some weird indirect way be doing just that.
Bentley Turner
>it might just be that thing is pushing off of something that's hard to detect well, that's not reactionless thrust so it's not really what we're talking about and my point doesn't apply
if it works it would literally be possible to put in 2 units of energy and then 2 more and get 5 out which is, I think, pretty closely aligned to my example
David Perez
fuck thats enough. im moving to maths.
Michael Brooks
nah its fake. never trust chinks.
Ryder Collins
>It's a piece of space tech that sounds almost too good to be true really makes you think
Noah Morales
If the universe is actually a simulation,could this working be due to some underlying oversight in the system?
Sebastian Cruz
It's honestly a bit dumb to assume the universe is a simulation when discussing physics. It's a bit like saying "but what if there's a god that keeps everything together?"
Jason Hernandez
Most of the objections that rely on the free energy aspect assume that the memedrive would continue to produce constant thrust at high velocities. If that is true then it's certainly a damning fact, but it hasn't actually been shown to be the case.
Aaron Morris
Fuck off back to /r/emdrive or wherever you come from
Adrian Ross
Petition to call it REMdrive because they're all dreaming
Joseph Davis
Solar sails using lasers is a reactionless drive, and no one seems to care about that.
Cameron Morgan
because sails are gay
Cameron Rivera
I guess they are, but they're still only using electricity to power the lasers, which propels the craft
It has the same lack of expelled mass as the EM drive
Jose Hill
Serious it would need a constant line of sight to work, and as we all know laser beams disperse with distance until there is not enough repulsive force to push the sail.
Isaiah Price
There's also the problem of breaking if you don't have a laser set up at your destination.
Jordan Hall
Can actually be done by useing celestial bodys, as a brake.
Zachary Robinson
>Solar sails using lasers is a reactionless drive wrong
Cameron Miller
>useing celestial bodys, as a brake. umm... isnt that called crashing?
Owen Barnes
Only if you hit it. If you manage to stop before it hits, then no.
No. Whatever design you use, conservation of energy applies. If your design is a reflective one, then the laser suffers a doppler shift as it hits your sail. If you actually have a laser propulsion, then the electrons in you batteries that are in an excited state lose energy as they power the laser and go to a less excited state, losing mass as they do.
Leo Butler
Did they ever rule out the microwaves expelling the copper as propellant?
Easton Collins
underrated

What do you think, user?

I have a published paper that claims exactly that.

Pic related. It looks more like something heating up then cooling down, so my money is on some thermal effect. It wouldn't be with out precedent, there was something called the Pioneer anomaly, it was a very small acceleration (on the order of [math] 10^{-9} ms^{-2} [/math]) that was causing Pioneer 10 and 11 to drift off course, from the time it was discovered no one had much of an idea what was causing it, although there were a lot of """"explanations"""" for it, sound familiar? Well after years of investigation, accurate modeling of the interior of the probes showed that there was some anisotropy in the emission of radiation, and that when this anisotropy is properly taken into account, the anomaly disappears.
I'd put my money on a similar effect in the case of memedrive.
Lincoln Rodriguez
I fully believe that the meme drive works and I take great delight in the tears of Materialist philistines, BUT anything China says should almost be presumed false at this point.
