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.

It appears to use dark matter for propulsion. I.e. the low energy, sub-atomic soup of the universe which is not coalesced into an atom. Clarification: Like objects in a swimming pool the weight of an object is measured relative to the medium but the medium itself is not observed or factored.
In the EM drive the microwaves likely energize the dark matter imparting electrical polarization which creates pressure -i.e. thrust.
Considering 3/4s of observable mass is composed of dark matter it’s unlikely the EM drive would work in a true vacuum. But even outer space isn’t a true vacuum. If they could increase the energy of the microwaves a couple million times they might be on to something.
1) EVERYTHING is measured relative to where you are standing. The measurement of the same object you take would be different than the measurement of some one moving (relative to you) - but remember, to him he is standing still and you are moving. That’s what ‘relativity’ is all about.
2) there is nothing about the ‘path’ through curved space that affects red-shift. Only if something is moving towards or away from you.
Great book.

Except it isn’t.
