makes sense. it's really em fields which cause atoms to interact as they do; that transfer force. and they extend for infinity. well, r^2 integrable.

and einsteins equations really show a conservation of mass-energy-momentum. e^2+p^2*v^2=m^2*c^4, so conservation of momentum can be violated just as well as conservation of mass can - so long as the full equivalence relationship holds.

The EM drive is based upon Shawyer's misunderstanding of what "group velocity" entails. Sonny White's QVF model does pose a possible explanation for thrust from it, if you believe as he does the vacuum is full of foam.

Thanks for the info. This is foreign to me.

Any relation to http://en.m.wikipedia.org/wiki/Casimir_effect ?

I was keeping up with this at one time. It is my recollection that Shawyer got his idea from having to constantly (but inexplicably) correct satellite positions. He concluded that the anomaly could be explained if he postulated thrust from the microwave transmitters.

If his idea really is based on his experimental evidence, I will keep an open mind about it. At this point I am assuming he is either a con man, or he has stumbled onto something that produces a real result.

I am not much concerned about his explanation of how the device works. If he was motivated by an effect, he may be explaining it incorrectly, but that does not make the effect non-existent.

That being said, I have more confidence in Dr. Woodwards science and math than I do in Shawyers.
