We are using different radii. ,,,
Ok...so if I am following the latest exchange correctly, then these devices dimensions MUST be in complete sync with the given frequency in order for them to work at all? Or do they just function very poorly if the match is not exact?I also recollect long posts in the other thread about how difficult it was to attain and maintain the correct frequency - something about it shifting?
Quote from: Mulletron on 01/17/2015 03:06 pmThere is essentially a news blackout on the experimental side from NASA.The problem is, if this drive really works, the defence implications are huge. Those in charge might feel it would not necessarily be a good idea to go public with it -- especially from the US perspective. Remember that 'Sputnik moment'?

It turns out that this self-acceleration does not actually violate any physical laws — such as the conservation of momentum — because at the same time the particle is accelerating, it is also spreading out spatially in the opposite direction.“The electron’s wave packet is not just accelerating, it’s also expanding,” Kaminer says, “so there is some part of it that compensates. It’s referred to as the tail of the wave packet, and it will go backward, so the total momentum will be conserved. There is another part of the wave packet that is paying the price for the main part’s acceleration.”It turns out, according to further analysis, that this self-acceleration produces effects that are associated with relativity theory: It is a variation on the dilation of time and contraction of space, effects predicted by Albert Einstein to take place when objects move close to the speed of light. An example of this is Einstein’s famous twin paradox, in which a twin who travels at high speed in a rocket ages more slowly than another twin who remains on Earth.
I been in contact with NASA on this and the lack of direct response has been marked. They will talk about the warp drive and other work, but will not even mention the EmDrive in their replies. It's as though they cannot speak its name...I also have it from other sources that NASA have requested that they do not discuss NASA's work in this area. If you can find any official NASA public comment on anything related to their EmDrive work I will be impressed! It does look like a blackout to me.
If NASA really decides to go silent on this, that would be a strong indication that the effect is not only real, but imminently useful. For those in the administration that might feel going silent is the optimal approach, I would suggest to them otherwise. Attempting to impede and to cover such information in the age of the Internet is futile. Though it may slow the efforts within the U.S. to reproduce and harness the effect, this is a multi-national effort, and the advancement and evolution of our species will continue in its progression despite such efforts. To any and all leaders within NASA or other governmental organizations whose first reaction is to suppress, please consider that such an approach is very 20th century.

If they verified it works, they could be already working in military applications, and probably on a few civil ones. Unlimited range space probes would be a very good publicity stunt for them, for proving their technical superiority.
Would you say it's a case of shutting the stable door after the horse has bolted?
Quote from: Star One on 01/21/2015 07:20 pmWould you say it's a case of shutting the stable door after the horse has bolted?It probably is, but I don't think it would be an attempt at censorship by making all information about this a secret. That horse already left the stable, as you say.In all probability (if they already know this exists and works outside of the public peer review process) they are trying to prevent the spread of sensitive "next step" information, allowing potential enemy powers to quickly develop the same technology, just by reading the same public reports we on the Internet do.It's not the first time I have read people pleading for keeping the reports about Q-thruster technology a secret, because in case of being true, they would certainly be matters of national security.
Great ! In my 2 minutes at a time I'm off to figure out why df/c = the momentum, but in the accelerated frame of reference.Added: http://scitechdaily.com/way-self-propel-subatomic-particles-without-external-forces/"We find these shape-preserving Dirac wavefunctions to be part of a family of accelerating quantum particles, which includes massive/massless fermions/bosons of any spin."
So does that mean we shouldn't except to hear anything more from the US on this & if that's the case what does that mean for civil applications?
