Dr. Rodal:I missed your question last night on whether the warp-field interferometer cylindrical cavity had any dielectric inside of it. The answer is no it does not, except for the nanometers thick aluminum oxide coating that bare aluminum develops as soon as it is exposed to the oxygen in the air.Next you asked about whether there where optical windows cut into the center of the cylindrical resonant cavity end caps or not. Well, yes there has to be optical window holes for the 633nm laser light to pass through the 7.23cm gap between the endplates of the aluminum cylindrical cavity. We also added two, three inch long, 0.50" OD by 0.25" (6.35mm) ID threaded aluminum tubes to the resonant cavity endplates, see attached picture, that function as two RF chokes that keep the 1.48 GHz RF from leaking into the lab area. So the laser light passes through these RF choke tubes and the cylindrical cavity where the peak ac E-field of 900kV/m is present along the entire 7.23 cm long laser path while in the resonant cavity and an exponentially reducing E-field in the RF chokes since these are cylindrical waveguides well into their cutoff mode since the RF wavelength at 1.48 GHz is 202.7mm. BTW, we are going to add optical borosilicate telescope grade flat windows to the ends of the RF chokes when we get around to pulling a vacuum in this 1.48 GHz resonant cavity.Next a clarification. We used a cylindrical cavity for the warp-field interferometer instead of a frustum shape because we didn't want to create a force with this unit, but instead we needed just a large densification of the Q-V along the active path length of the laser beam while it was traversing the resonant cavity's centerline volume. And this is the main difference between the Q-thruster and a warp-drive. In Dr. White's warp-field conjecture you first have to have an Q-Thruster derived acceleration vector to work on and then you engage the a toroidal warp-field around your accelerating vehicle that then multiples the initial Q-Thruster provided velocity vector by the selected warp-factor. Thus if you have an initial velocity of say 0.01c towards Alpha Centauri with a warp factor of 1,000, your effective velocity becomes 10c while the warp-drive is engaged.Best, Paul M.

Yah, the EM and ME thing is important. ME generally refers to mach effect (Woodward) mass fluctuation thrusters.

Need a real time operating system (RTOto clear that problem, a RTOS system we don't have.QUESTION 3: Did you plot three dimensional plots to look for power peak distribution distributions looking like ring-shaped circular-waves, corresponding to path length changes associated with such frequency (in question2) ?Yes, see attached picture.QUESTION 4: Did you conduct additional tests to confirm repeatibility of the measurements?Yes Michael Rollins performed four additional 27,000 on/off data sets under the same 30W RF drive condition and obtained similar test results for all five cases. Mind you at 20W RF input there was only a hint of the space-time compression effect visible above the noise platform. QUESTION 5: One would expect such ring-waves to display some statistical distribution, therefore using measures of central tendency like different truncated mean measures ( http://en.wikipedia.org/wiki/Truncated_mean ) of the multidimensional power spectral density data may be particularly helpful in assessing the data (at least I have found so in assessing massive data for different problems that also involve 1/f noise)I will point that out to Dr. White tomorrow.QUESTION 6: Has NASA Eagleworks addressed the issue with air refraction raised in this paper by Lee and Cleaver from Baylor University?:http://arxiv.org/ftp/arxiv/papers/1407/1407.7772.pdfIn particular, has NASA Eagleworks assessed the likelihood of the path-length-change measurements being the result of transient air heating ?See Dr. White's preliminary assessment of that issue in the attached slide. Ultimately though we will be running the warp-field resonant cavity with a vacuum contained in its active volume to get rid of all possibilities of air heating problems.Best, Paul M.

Mulletron:No I hadn't but thanks for the pointers. So what to you think an asymmetric difference of ~1x10^-18 m/s in velocity of light bring to the table? That the vacuum can be differentially polarized by applied E and B-fields in a volume, in this case dc E&M fields??Best, Paul M.
@Paul March: since the warp drive is to be considered then as ontopic in this thread, how exactly does Dr. White theories deal with time-travel to the past in superluminal speeds? I guess that would be a major point of any space travel related applications of a warp drive.
I know Mulletron. What I want to know is exactly how Dr White theory deals with superluminal speeds, which most physicists say leads to time-travel to the past and all the paradoxes that surface from that.According to the video I showed from Dr Davis, superluminal speeds WITHOUT time-travel to the past are possible, if the light cone is tilted from 0 to 90 degrees only...I think this question is related to spaceflight applications exactly because time travel IS an issue at relativistic velocities (to the future) and superluminal velocities (to the past, but not according to Dr Davis)This question is probably more related to the spaceflight applications of a warp drive than the pure theoretical issues of how EM and Warp Drives work on quantum level, since the first is a result of spaceflight application while the second (which is being discussed in this thread) is not.
