So, I know you guys probably hate this topic, but I don't think stop looking into it is the solution. Figuring out what's wrong with the experiments would also bring new knowledge to the table, and make future experiments even more careful (The Opera neutrinos are an example of that).

What I'm asking is: is there a possibility of a quantum phenomenon, like quantum tunneling, being able to produce the amount of thrust observed in the experiments (which is tiny, but seems to me way higher than it would be expected by particle quantum tunneling, that is, if quantum tunneling can even transfer momentum. I'd argue it can, since its nothing more than a particle going from a higher "energy state" to a lower one, but the fact that it does this in a non-classical way, collapsing its wave function in a "region" where the classical possibility for the partical to be should be zero makes me wonder).

Quantum tunneling may play a whole, but if it does, is it so huge to the point of explaining the thrust? And is there any fringe reason why would quantum tunnelling would transfer so much momentum, given that it would happen so rarely in the EM drive device, if it would account for all the reported thrust, there would be some serious imbalance in the equations, as if tunneling borrowed energy from somewhere else, energy it shouldn't have if the particle would remain classically contained.

As I said, maybe not exactly quantum tunneling, but something else. We learned about hawking radiation somehow recently, Can you, quantum physicists, envision an effect that would account for that thrust being measured? I know the standard explanations, like "pushing into the vacuum", and other things.

I doubt any of you guys haven't spent at least some time entertaining the notion of the EM drive not being a fantastic beast, but simply something that needs an explanation as to how it works. I really doubt that, if it works, it would violate conservation of momentum. We just don't see how it would be possible without that violation, so we push it aside. That's, in my opinion, not a thing scientists should do. They should instead be trying to disprove the EM Drive beyond a shadow of a doubt, and if they can't they should start focusing on how it fits the standard model, and if it doesn't...! Well! How great would that be? How much new reasearch could be derived from it? who would be the first to win the Nobel prize on this matter? Isn't new physics all you guys have been looking for? what if you don't need LHC to get it, but simply a bizarre thrust obtained from turning on a round-frustrum shaped microwave oven?

So, I'm not a physics guy by any means, but here's my stab.

If I had to guess, I would say that by enclosing the chamber and emitting radio waves into it, you are altering the state of the inside of the chamber. If a vacuum does in fact have quantifiable mass, which some theories of physics point to, it could be potentially be raising the energy level of the vacuum inside the chamber to a great enough degree that the differential could be exploited. We keep calling it reactionless, which I think is wrong because thrust indicates reaction.

If we consider that vacuum energy exists, and has mass, and exerts gravitational force, then it should stand to reason that by enclosing that vacuum and applying energy to it would result in an exploitable differential. Therefore, it wouldn't be reactionless, but instead it's reaction would be highly efficient. A parallel here would be nuclear energy, it takes a great amount of fissile mass to generate energy, but if it was 99.999% percent efficient, it would require a relatively miniscule amount of fissile mass to produce similar power output. The closer you get to perfect efficiency, the less you need to get a net gain;the less you need, the harder it becomes to measure.

I'm sure that the shape of the drive chamber has some effect on directing that thrust, by having one side larger than the other, the energy differential should be greater towards the smaller end and vice versa. In my mind, that would create a system in which the vacuum inside the chamber is constantly seeking entropy and providing thrust in some form. Mind you, I'm not a physics guy, I don't even have a college education right now. So I may just be spouting nonsense.
