EVERY has an equal and opposite reaction. Or it should. It's how rockets work: they accelerate forward by burning fuel and ejecting exhaust in the opposite direction.
If it works.
Many physicists believe it is a simple – but minuscule – error.
It's an error that has been down since the Shawyer EmDrive was first run in 1998.
Tests by the world's most advanced propulsion engineers, including NASA, still capable of producing measurable thrust.
And, in the frictionless environment of space, that thrust accumulates.
It's a prospect that the US Defense Advanced Research Projects Agency (DARPA) sinking a speculative $ 1
"DARPA should invest modest sums to experimentally assess such claims, as well as where credible experimental evidence exists", former DARPA researcher Jess Sponable told Popular Mechanics.
PURSUING THE IMPOSSIBLE
It's just a cone of copper. One end is sealed.
Microwaves do produce pressure.
Microwaves do produce pressure. Just not much of it.
The idea goes that the microwaves strike the closed end of the copper cone product pressure – in essence giving it a 'push'.
This is where the physicists have a problem.
They argue this is exactly the same as trying to push a car by leaning on the wheelchair while sitting in the driver's seat.

NASA's Eagleworks has found it. China's Northwestern Polytechnic has found it.
But, given the new international arms.
Nobody, however, can explain it race, that does not matter.

The science is entirely speculative. And utterly unfounded.
But DARPA has kicked off an initiative it calls NLM (Nascent light matter interactions).
It's re-examining the properties of electromagnetic and light waves.
Specifically, it wants to test the highly
Known as balance radiation, it is speculated this could be the unaccounted for 'fuel' that provides the thrusts of the throne.

Called Quantized Inertia, it's a radical concept. It would therefore go against existing theories of the nature of dark energy and dark matter. But these remain highly speculative, too.
Most physicists believe the 'thrust' being recorded by the EmDrive is unaccounted for external influence – as the impact of the Earth's magnetic field on the copper making up the cone.
So DARPA wants to recreate this thrust through a new kind of experiment.
Instead of microwaves and copper, they will fire through a loop to see how they interact. And another test will bounce lasers off assymetric mirrors.
Theoretically, these should produce the same effect as the EmDrive.
If successful, the results would be revolutionary.

Satellites would not need to carry heavy fuel into orbit. Instead, they could coast at will.
Mostly, it would be good to have modern physics.
Mostly, it would make much easier. Einstein's theories of general relativity and special relativity would have to be revisited. As would Newton's third law.
But that has not happened, yet.
