They're not currently tracking the resonant frequency as it changes, so the thrust is only present for a moment as they cross through it randomly. 12:06 < lsneff> Assuming the thrust is present at all, of course. 12:07 < lsneff> But it does seem to imply it's not an interaction with the Earth's magnetic field. 12:08 < fenn> i don't think that was ever a serious consideration. it's easy to null out by rotating the whole setup 180 degrees 12:10 < nmz787> that's what they said about detecting the luminiferous ether 12:11 < fenn> i never understood that either 12:11 < fenn> isn't "frame dragging" basically the expected observation of the ether theory? 12:13 < lsneff> Huh? 12:13 < lsneff> What did they say about detecting the ether? 12:15 < fenn> ok so frame dragging is a result of rotation, but they were expecting an effect from the linear movement of earth in its orbit about the sun 12:17 < lsneff> I didn't realize the luminiferous ether was a modern theory. I thought that was a 1600s thing. 12:18 < fenn> the michaelson-morely experiment used a crossed beam interferometer, that is to say, a 90 degree offset between the two light propagation paths 12:18 < Urchin[emacs]> lsneff: how? 12:18 < nmz787> I still dont disregard it completely... I'm not so sure it won't pop upp again with i.e. dark matter or something 12:18 < fenn> gah spelling 12:19 < Urchin[emacs]> lsneff: 1600s had nowhere the required understanding of electricity and magnetism to the point where the luminiferous ether would make sense as a hypothesis 12:19 < fenn> nmz787: i agree, they overreached with "ether was shown not to exist" - no, actually they showed that it was not stationary, if it exists 12:21 < fenn> relativity provides no insight into where light waves come from or why they're waves 12:21 < lsneff> Urchin[emacs]: I was confused with the name. The term originates in mythology, but the luminiferous ether was an 1890s theory. 12:21 < fenn> "the pure upper air that the gods breathe, as opposed to the normal air" 12:22 < lsneff> Indeed. 12:23 * L29Ah feeds proton gas to fenn 12:24 * nmz787 feeds dephlogisticated air to L29Ah 12:24 < fenn> i can feel my godliness increasing already! 12:25 * fenn shoots proton beams 12:25 < lsneff> In this context, I've found the space network theories very interesting (LQG, and wolfram's), since they are, in a vague sense, an ether. 12:25 < nmz787> I knew some people in high school that huffed ether, if that's relevant 12:27 < fenn> i also find it interesting that we use basically a scaled up version of the michelson-morley interferometer to detect gravity waves 12:28 -!- filipepe [uid362247@gateway/web/irccloud.com/x-cqeeasxaospbtxav] has quit [Quit: Connection closed for inactivity] 12:28 < fenn> if they had detected gravity waves we might have had an entirely different set of prejudices in physics through the early 20th century 12:34 < lsneff> If the mach effect/MEGA drive turns out to be a result of new physics, it'll be quite poetic that our spaceships will be sailing to the stairs on the collective thrust of billions of tiny MEMS devices oscillating at gigahertz. 12:35 < fenn> i thought the whole point was that it was NOT new physics 12:35 < lsneff> Well, unaccepted physics 12:59 < lsneff> https://charted.space/notes/Making%20Starships%20and%20Stargates%20-%20The%20Science%20of%20Interstellar%20Transport%20and%20Absurdly%20Benign%20Wormholes.pdf 12:59 < lsneff> "Making Starships and Stargates", by James F.
