'Impossible' EmDrive Space Thruster May Really Be Impossible

The laws of physics have won again, it would appear.

For the past few years, researchers at NASA's Eagleworks advanced-propulsion lab have been putting a controversial and potentially revolutionary space engine called the EmDrive to the test.

The EmDrive, which was originally developed by British scientist Roger Shawyer in the early 2000s, purportedly generates thrust by bouncing microwaves around inside a conical chamber. Because the engine doesn't require any fuel, it could theoretically make spaceflight far cheaper and more efficient, opening the heavens to exploration

The EmDrive really shouldn't work. The engine doesn't blast anything out a nozzle, so Newton's Third Law of Motion — for every action there is an equal and opposite reaction — doesn't come into play. Nobody really understands how the claimed thrust could actually be generated.

And now it seems that the previously detected thrust was illusory, at least according to a team of researchers in Germany. They built their own EmDrive and tested it in a vacuum chamber, as the NASA researchers did.

The German team picked something up as well. But follow-up analysis "clearly indicates that the 'thrust' is not coming from the EmDrive but from some electromagnetic interaction," the researchers wrote in their new study, which you can read here. That interaction is likely between EmDrive power cables and Earth's magnetic field, the team concluded.

If something can’t work, then it doesn’t. In other words, if there’s an unassailable principle, and you try to do something that violates the principle, it won’t work.

Principle: energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.

So if you try to get energy from nothing, you will not get any energy. Doesn’t matter if you yell and scream, or write scholarly papers, you will not get any energy from nothing.

You lost me a bit. But I see your point regarding light in a straight line through “curved” space.

Assumptions: Our galaxy is moving in space. Our galaxy is rotating as it moves through space. Our solar system is in one arm of our spiral galaxy (in rotation). Our solar system is moving within that arm of our galaxy with our star being at the center of the movement. Then our planet is moving around our star. If observed from a stationary point in space (no idea how you could determine what that would be), how would our planet be observed as moving in a straight line. Could the distance our planet has traveled be measured from that observation?

Similarly, If light is observed from a single point in space, in a straight line, and the light travels along a curve in space, that we cannot see, how is the red shift affected as component of the distant the light travels before we see and measure it? We determine distance based on how far light has traveled at a constant speed. Does it not suppose that light traveling through curved space (gravity) would travel farther, and thus corrupt the data?

Odd, it looks like it should work...

Keep in mind that there ARE magnetic fields in space. So certainly possible that the device would work just fine in space.

That presumes the premise is true. Over the thousands of years humans have been on this earth, numerous “unassailable” premises have been formulated, and ultimately proven to be false. I propose that many/most of these “unassailable” premises will eventually be proven false as well. Thankfully, there are those who continually challenge these principles.

Heck, everybody knows Aunt Em and Tesla invented the Em Drive back in the day...

She only used it once to drop a house on a witch. Once she realized the power of the Em Drive she burned the plans so Henry Ford couldn't steal the drive for evil.

Ah, but that was the Aunty-Em drive.

Completely opposite principals.

The easiest way to imagine it is a bowling ball sitting on a foam cushion.

The foam represents space- he ball represents how a ‘mass’ distorts it, and the space curves around it.

You can easily see that if you roll another ball around it, the curve will allow the ball to circle the bowling ball.

Imagine that...the laws of physics still apply. Obama should have signed an executive order decreeing them to be no longer valid.
Some of his minions were grilling some GM execs about why they didn’t make the product Obama wanted them to. The reply was that the laws of physics did not permit it - and Obama’s minions got all excited over the prospect of Obama overriding the law to get what he wanted.

So, launch one and take it to space, and test it there. See if there is ‘thrust’, or if the now labeled “illusion of thrust” is caused by “interaction is likely between EmDrive power cables and Earth’s magnetic field, the team concluded”.

Simple enough answer - test it out, in space, away from the Earth’s magnetic field.

Fine, then lets invent the magnetic field cable trust engine.

Didn't Thomas Townsend Brown already do this?

Thanks BenLurkin. Any test of it should be done in space, period.

Nice pic of TT Brown.

Also, kudos, very arcane reference!

There are several articles on this and at least one says the results are inconclusive until someone makes a shield that prevents interaction with the Earth.

So, we just need something the mass of earth to take with us when we go.

That should be easy.
