I read in a few articles that popped up a few days ago in multiple news sites where it was said that NASA has confirmed a propellant-less thruster possibility. (this, for example: http://www.wired.co.uk/news/archive/2014-07/31/nasa-validates-impossible-space-drive ) They think the microwaves resonating might interact with the so called virtual particles of vacuum to create thrust, to push against.
What do you think about this? Have they found a long sought for way to push against space itself? Might this be better explained with un-popular pilot waves being produced and pushed against without matter particles? Or you think this is complete bogus?
I even read in a similar article where it was mentioned (of course, I cant find the exact one as there are quite many of them popping up) that using superconducting materials and some extra fine-tuning they could create a ton of thrust using one kilowatt of power, which seems rather too good to be true.

It seems that space contains radiation and magnetisms in abundance; (thought there could be some debate over that,) and there is gravity.
It would seem that space travel could best be accomplished using one of them. 
I would start with magnetism.

That the test results show a violation of the conservation of momentum is very interesting.

It sounds like there are those that want to arrest him for breaking that law.
Shawyer says he's innocent and the law was not broken. Wiki

I like the guy, love his work.

The next question is why is the Johnson Space Center copying (steeling?) it?

Steeling it against what? Criticism? You have absolutely no idea why I made that remark do you?

ya no one like the law of physics like C of M to be voilated (poor humor on my part)
Shawyer says, "the have not been voilated" did you know that?

I read that Roger Shawyer invented it and now others JSC and Chinese are copying it.  (steal) maybe that's ok but I don't think, so is that wrong??

Nothing impossible here. Google for "radiation pressure" to understand the concept of photon momentum. Now consider a resonant cavity with a hole in it. The cavity is filled with photons exerting pressure on every part except the  hole, so there is a net accelerating force away from the hole.

It's easier to demonstrate in a laboratory with more energetic photons (lasers are a good source) but the efficiency of microwave generation, especially in a vacuum, is much better. Classical physics (it goes back to Kepler) and clever engineering - the essence of space flight.
