Here's the problem with using the quantum vacuum that way. The difference between the quantum vacuum and the old luminiferous aether is that the quantum vacuum, at least according to the best theories we've got, is Lorentz invariant. It should look the same in any inertial frame of reference. Which means it can't carry any momentum, so there's nothing to push against and have it remain vacuum. The only way to "push against" it is to transform it into a state that does carry momentum--and that's not vacuum any more, that's a state with some real particles in it. So the best you've got is still just a photon rocket.
@MattMcIrvin
4 жыл бұрын
By the way, if you're _really_ clever you might be thinking of a secondary objection here: "Well, suppose we 'borrow' some momentum temporarily from the vacuum, in the manner of a virtual particle in a Feynman diagram, move over a little and give it back? That doesn't violate conservation of momentum over the whole interaction. Suppose we start out in a frame where you have zero momentum. One minute you're here, the next minute you're over there, but your momentum is still zero when it's all over." That actually doesn't work either, and it's again because of Lorentz invariance. In fundamental physics, every symmetry is associated with a conservation law, via Noether's Theorem. Conservation of momentum is the conservation law associated with translation invariance--the laws of physics being the same in all places. But if you instead take Noether's theorem and plug in invariance under a change of inertial reference frame, what you get out is a tricky-to-state conservation law that basically says the center of mass (technically, center of energy) of a system MUST move at a velocity corresponding in the usual way to its momentum. The interesting thing is that there is no corresponding law for *rotational* motion--there's rotational symmetry, which gives conservation of angular momentum, but there's no "center of energy motion" restriction--which is why a non-rigid body in free fall can reorient itself in space, by messing with its moment of inertia, without violating conservation of angular momentum. This is how cats land on their feet (classically--no quantum shenanigans needed). But for linear motion this trick doesn't work.

After having read the article, I can see at least one potential source of unaccounted-for error. Most metals have a tendency to absorb significant amounts of atmospheric gasses on their surfaces. In high vacuum chamber experiments (CVD, electron microscopy, etc) the vacuum vessel has to be brought up to high temperature as basically every part in the system out-gasses. Due to the non-trivial amount of power being used and extremely asymmetrical nature of their apparatus, erroneous thrust might be generated from thermally induced out-gassing. They never ran the system for long enough to reach thermal equilibrium and re-introduced atmospheric pressure after only a few runs. Just a thought.

@scott manley There are a few theories out there that suggest the EM drive doesn't break the laws of physics and that it also doesn't do anything funky with 'quantum vacuums' or other such nonsensical explanations. Maybe try to find those, might be an interesting read for someone like yourself with a far greater understanding of physics than me. Also, being afraid of "the laws of physics being changed right under you" might not be the best mentality. Being skeptical is, of course, expected and reasonable. However, being scared of change simply because it's "scary" is not so smart. The laws of physics allow us to model the universe and make accurate predictions based on what we have observed in the past. Throughout history these laws have been altered numerous times by new data, allowing us to more accurately predict and model whats going on around us. While I'm not defending the EM drive (though i do believe it will turn out to be bogus), I'm also not going to discount the research that has been done on it thus far. I've heard rumors that the EM drive is being tested aboard the USAF's X-37 and on board China's new orbital laboratory. Interestingly, amateur astronomers who track the location of the X-37 claim that it has changed its orbit far more than its, albeit assumed, delta V should allow, possibly hinting at some other form of propulsion being utilized. I say some group (probably NASA) send one of these into space (without it being shrouded in secrecy) and give it a whirl, put this debate to bed once and for all. On a side note, your videos are always great and provide an outstanding means of learning about space after a long day of work. Keep it up :)

Isn't this the same sort of principle as the Casimir force? On the face of it, the Casimir force breaks the laws of physics because you "get force from nothing," via 2 parallel plates in a vacuum. But then quantum mechanics comes along and states that in a vacuum exists virtual particles and the cutting off of wavelengths between the plates results in a lower pressure than outside the places, resulting in an inequal force pushing the plates together. Wouldn't the same kind of principle apply where due to one end of the cone being narrower than the other, a similar situation arises where there is a lower "pressure" at one end? I've always been very interested in ways to exploit zero point energy and it seems to be a part of physics where a lot of mystery still lies.

There is no 'force from nothing' in the quantum vacuum example. Quantum mechanics simply 'discovered' a new set of interactions on a micro scale. This is not a micro scale, and thus quantum vacuum effects would be largely irrelevant or non-existent (likely both).

"Wouldn't the same kind of principle apply where due to one end of the cone being narrower than the other, a similar situation arises where there is a lower "pressure" at one end? " No, and even if it did, it wouldn't depend on input power. It would be a property of the geometry, just like the real Casimir effect.

Ath Athanasius Jaffe is a smart guy, but I can tell you that not that many people take this sort of explanation very seriously. This is because the Casimir effect, or related effects, show up in a variety of other contexts where there are no atoms and no van der waals forces. For example, the most common way to think about particle physics at finite temperature is to calculate a kind of Casimir effect in a space that looks like a torus. Or, if string theorists are to be believed and we live in a 10 dimensional space of which several dimensions are compactified, there would be a Casimir effect associated with this compactification. It is really the boundary conditions that are important, and those do not need atoms to arise.

John Bode wrote in a comment below- "For EmDrive to work as advertised, a lot of current physics has to be wrong - not just incomplete, but wrong ." Not really. Have you heard of "Virtual Particles"? We have verified some of the theories such as the Casimir Force. It has been verified enough that we have to compensate for this force when designing micro-MEMS devices. So the physical effect of these virtual particles CAN BE REAL. So what if you could build a device that can impart momentum onto these virtual particles in the short time they are "real" and not virtual? Does the law of conservation of momentum get violated when we do this OR did we just make the WRONG ASSUMPTIONS when we defined the "Closed System" (referred to in the Law of Conservation Of Momentum) and we SHOULD include interactions with the quantum "Virtual Particles"? Perhaps the effects that these virtual particles on our reality could explain "Dark Matter" and Dark Energy? Have you heard about one of the ways we make anti-matter? We basically generate a big enough electric field that we "exrtract" an anti-electron from the virtual "soup" of particles. When these particles are created they must have some kind of momentum. Did we just create physical "Momentum" from nothing but energy?

Energy is a strange thing sometimes, when I picture how this thing is working in my head.. I am kind of reminded of one of the ideas for faster than light travel. At least I am in the end if my fever dream idea of how this is working. If i picture instead of a microwave in that thing, a ball i see things differently than i likely should. You see, every time that ball would bounce off the sides it would loose energy, but energy is nether destroyed or created, thus it is being transferred. that ball would bounce of the sides until it gave its last bit of energy and came to a stop. But if you follow the path of that ball, it would start by hitting the sides really fast and hard, thus transferring its energy to the sides of the cone. But the amount of energy being lost would drop, so one part of said cone would be collecting more energy than the other. Picturing this in my head, the small side would take a lot of the energy, while the wide side would be taking less energy and said energy would be spread differently and it would be being transferred at a different pace as this ball was giving up in the smaller part. One of the proposed ideas was creating a ripple in space, where you had a high energy area ether in front or behind said ship, and a low energy area on the other side. This would bend time and space in such a way as to pull the ship up to speeds faster than light. Well in the EM Drive, the energy distribution is likely doing something along those lines. ..

I'm going to mention something that is also very high in the "piss off physicists" list (I'm one, I know) but at least does not involve breaking fundamental laws of conservation: what if the EM drive is simply pushing against something that *does* have a preferred frame of reference - sort of like the 'ether' of old? So not the quantum vacuum, I imagine, which should be Lorentz-invariant, but something physical. One thing that comes to mind is dark matter - we don't know what it is so it could be literally anything, and for all we know it could be weakly interacting and pretty much all around the place while being approximately dragged along within our galaxy's reference frame. Another thing is the CMB. In theory the CMB should be uniform in all directions, but if for example I were travelling at relativistic speed I should see it blue-shifted in front of me and red-shifted behind me, and as a result the photon pressure should slow me down until I'm back to seeing it uniformly in all directions, right? Of course that takes VERY high speeds and VERY long times but I can imagine it being possible, which at least provides us with a possible frame of reference the EM drive could be mysteriously coupling with to generate its thrust. As to the how, be my guest... Casimir effect comes to mind but shit's not supposed to work this way.

Hi, Scott. I have a theoretical question. If I built an overunity motor that required X joules of input energy to run and it produced X+Y joules of output energy so that there was enough output energy to keep the motor running plus additional energy to power other devices, then what would you, Scott, need to observe, inspect, or measure in order to be convinced that it was real as in the following: -How long would the motor need to run? -How many revolutions would it need to make? -How much overunity output energy (Y variable above) beyond the input energy (X) would it have to produce? For instance, if there was enough output energy to power the motor in order to keep it going, and to power some LEDs at the same time, would that be enough output energy for it to qualify as an overunity motor? Aside from powering some LEDs and continuing to run, wouldn't overcoming air resistance and bearing friction alone be enough to show overunity performance?

If we as species, really want to expand our horizons in space exploration, we absolutely must develop new propulsion options. Although advances have been made the achilles heel of space flight is the limitations imposed by having to use massive combustion engines and the accompanying massive fuel loads...which comprise around two thirds of current rockets. I have not heard of this particular propulsion method. In theory it sounds great...but that's the problem, they all do but never amount to anything.....peace.

You and a bunch of other people are responding: "it cannot work because theory doesn't add up and if theory says different than facts we will ignore the facts". Come on. It either works or it doesn't. If building this is no big deal than build it, TEST IT and prove it's not working instead of just claiming pure theory to be much more important than facts. Since when theories are foolproof? I thought entire science was about making theory fit the facts and not the other way around?

I'm not a physicist, but I'm kinda wondering if the effect could be explained by interaction of the Microwaves with the earths magnetic field lines? I can imagine them pulling or pushing of of the earths magnetic field and there being a differential in push/pull due to the difference in area between the front and back of the chamber due to the larger volume of field lines at the wide end. (This offcourse provided the magnetic field lines could penetrate the copper hull. But as far as I could find a Faraday cage shouldn't block those). I'm probably just ignorant of the reason why this is impossible but I'm curious what that reason would be.

A: No. Such an interpretation of my results is truthfully a mystery to me. Already in the abstract of my technical paper I write clearly and precisely that I cannot confirm nor disprove the effect of the EMDrive. It is true: We indeed measured thrusts similar to the predictions of the EMDrive, but also in directions that should be null. I also write that I presume that magnetic forces from the cabling cause this effect. This is why I did recommend in the article that further testing be done to sort out these (and other) possible causes. Q: How do you fundamentally view the concept of the EMDrive? A: From a theoretical standpoint, the EMDrive makes absolutely no sense. Because, in essence, it would contradict the conservation of momentum. Time and again I've been asked by my students and colleagues for my opinion, especially after some experimental data from NASA became available. That is why I wanted to conduct testing myself, to see if I could come to similar results and whether I could delete the effect through better shielding against thermic/electromagnetic effects (what most critical scientists expect). Since I have always been interested in new thrusters, I was naturally very eager to see the results myself. Q: And was this shielding successful? A: Our tests have shown that we can indeed produce similar results -- except this time we had more sensors (e.g. temperature measurements) -- and the possibility to implement some shielding. In doing so we found that there can be significant interference by the magnetic field of the cabling, which we could not completely shield against, and that the same thrusts are observed when the thruster was firing into a direction that should not have shown thrust on the thrust meter. Q: And what does that mean for the experiments so far that supposedly prove the effect of the EMDrive? A: Our testing shows that in both the apparatus of NASA and that of the inventor not all sources of error have been identified yet, and that within the scope of our accuracy of measurement we have had a baseline measurement -- with the accuracy of measurement matching the claimed effect. Hence with our apparatus we cannot comfirm or disprove the EMDrive thrusts. Further testing is necessary. Q: How do you then explain the many news items that state that you have successfully and independently confirmed the effect of the EMDrive? A: Truthfully, it is a mystery to me that these websites claim I have validated the EMDrive. At least there were also a few differing news items. I believe that everyone want and hope that we find something new. Unfortunately, the time hasn't come yet -- hopefully, though, the future will have one or the other surprise in store for us regarding this. All I have set out to do is to scientifically look at a number of effects that lead to a wrong interpretation of test data. Q: Do you yourself plan to conduct further experiments regarding the EMDrive to, say, check more sources of error? A: I am convinced we now have an apparatus with which to continue -- the interest of the students is certainly there. I think that specifically the topic of EMDrive is an excellent educational project where you can learn to identify sources of error that may not seem readily obvious. _

How about a photons and phase shifted photons. They erase each other by the end, so you can't detect anything, but they still pushing.

work = force * velocity ??!! I thought it was work = force * distance Guess I lost points on that question lol.

Yep, he'd have meant power, or work per unit time.
