NASA's "impossible" EM Drive actually works though in violation of physics

The results of NASA’s tests on the ‘impossible’ EM Drive have been leaked, and they reveal that the controversial propulsion system really does work, and is capable of generating impressive thrust in a vacuum, even after error measurements have been accounted for.
The EM Drive has made headlines over the past year, because it offers the incredible possibility of a fuel-free propulsion system that could potentially get us to Mars in just 70 days. But there’s one major problem: according to the current laws of physics, it shouldn’t work.
The issue is the fact that the EM Drive defies Newton’s third law, which states that everything must have an equal and opposite reaction. So, according to Newton and our current understanding of the world around us, for a system to produce propulsion, it has to push something out the other way (in space, that’s usually combusted rocket fuel).
But the EM Drive works without any fuel or propellants at all. It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity. That motion causes the ‘pointy end’ of the EM Drive to generate thrust, and propel the drive in the opposite direction.
Despite years of testing and debate, the drive remains controversial. The bottom line is that, on paper, it shouldn’t work, according to the laws of physics. And yet, in test after test, the EM Drive just keeps on working.

Although this is really cool I'm going to give you a downvote because of who you are.

We should have test pilots and I know of a few that want to leave the United States

Something tells me that it's not actually violating the laws of physics.

The thrust-to-power ratio observed is 1.2 ± 0.1 Newtons per Megawatt, where 1.2 Newtons is the equivalent of the weight of an iPhone 6, while a Megawatt is enough energy to power everything in your entire house… and 649 others, all at once. Which is to say, it’s an incredibly large amount of power required for an incredibly tiny amount of thrust.

If the EmDrive violates Newton's 3rd Law of Physics it must imply that Newton (and what we've been taught) was wrong. It also implies that scientists know Newton's 3rd Law is wrong because why would they build a machine which is in direct violation of physical laws?
Question is: Why would scientists lie to us? Is it because they're learning a new realm of physics from FAR more advanced alien beings and feel the need to keep it quiet? Seriously, how do you explain scientists spending millions of dollars (perhaps billions) on a technology which shouldn't work?

I'm no scientist but isn't this your action/reation?

I don't think you're getting it...

The key is equal reaction

It doesn't violate the laws of physics. But yeah, it's pretty cool.
Posted on 11/10/16 at 9:26 am to mizzoukills
If they could get it to work on a larger scale with less power required, it would completely change the course of human history.

That's the mizzoukills we all know and hate.

I see what you're saying, but think of it like this: Imagine you're sitting in your car and push against your steering wheel. Will that motion cause your car to move forward?
That's what's going on here.

Sweet! Baby steps. Baby steps.
Now, they need to release the functional Terminators on the thugs.

The important thing to realize is that this is tremendously useful once youre in space.. and useless trying to leave earth

Violating the third law by pumping insane ratios of energy would seem to be expected if you ask me.
