I post here everytime someone brings this thing up...

I am currently working on it...

I have an idea of how it works, or how a similar device could produce a similar thrust...

The mechanism for my idea of where the thrust comes from has already been experimentally verified...

I am building the system currently and will be working on similar things during my post doc...

If it works how I think it works, I am going all in and building a ship...

I am gonna be at a university that facilitates start up businesses too and will go full ham on starting a "space development" company if the idea proves to be robust...

Let me ask you all a couple questions...

1) What would you do if you thought you knew how it worked? Would you tell people, keep it secret, develop it yourself?

2) Is it stupid to tell people how it works? Then someone or some company with the resources can scoop your ass to all hell...

3) Is this thing too dangerous to have out there? In principle, if this thing works it is icbm tier dangerous. I am gonna get v& for publicly working on this?

4) If this works, i want to start my own company and develop space exploration. I don't want fucking google or some shit buying up everything and pushing me, or whoever, out of the way. Is this paranoid?

>>8848356
this is a scalar model of qed. the positive and negative charged particles are given by \phi and \phi^{\ast}. the interaction for this theory is determined by enforcing, for the case of e&m, the local u(1) gauge invariance of the lagrangian. The interaction is there it is just written into the covariant derivative...

the propogator is computed via <0| phi phi' |0> and will look like

G ~ 1/(\delta x^2) in coordinate space

G~ 1/(p^2 -m^2) in momentum space

I work in quantum field theory in curved spacetime... its nice to take a trip back to the luxury of minkowski space every now and then... :)
>>
>>8848383
Fair enough.
>>
>>8848356
also, written explicitly out, the interaction would be something like

e \phi^{\ast} A \phi

A comes from F^2, with F^{\mu \nu} = d^{\mu}A^{\nu}-d^{\nu}A^{\mu}

This is the interaction that comes out of the local u(1)...

Why are people still pursuing this?

It must work even if no one has announced a good explanation why yet.

>The EMDrive is physically impossible.

Now, I'll give you that last one. Things are only physically impossible until they aren't; we don't know everything and can be proven wrong. But China has made some fantastic claims before, and they have provided 0 proof that they have a functioning drive.
>>
>>8850069
So you think the Chinks are just masters of banter/deception?

They sound fairly confident this is not a red herring.

http://www.ibtimes.co.uk/emdrive-chinese-space-agency-put-controversial-tech-onto-satellites-soon-possible-1596328

>"National research institutions in recent years have carried out a series of long-term, repeated tests on the EmDrive. NASA's published test results can be said to re-confirm the technology," Dr Chen Yue, head of the communication satellite division at the China Academy of Space Technology (Cast) said at the press conference.

>"We have successfully developed several specifications of multiple prototype principles. The establishment of an experimental verification platform to complete the milli-level micro thrust measurement test, as well as several years of repeated experiments and investigations into corresponding interference factors, confirm that in this type of thruster, thrust exists."
>>

Of course the people setting the red herring are confident it isn't.

I'll be convinced when they either give NASA a model to test themselves or get a peer reviewed report approved.

As if the Chinese government would allow that.
I don't see why you're so convinced they are perpetrating a hoax.

It they have a range of prototypes and measurements but lack a complete theory of how it works, they would be mad to publish.

That would risk giving away useful information that others could use to beat them to goal of a sufficient theoretical understanding from which and optimised engine could be devised.

Once someone has a thorough understanding of how it works they can patent the optimum design and that is worth billions.
>>
>>8850173

NASA haven't published shit, it's Eagleworks.

It was shown to be extremely lacking in testing for thermal effects. This is one of the tests they show in the paper. The device is turned off but the "thrust" only peaks then, and then there is an exponential decline just like a cooling curve. These effects get a mention in the paper but they crudely attempt to model them out under the assumption of uniform heating, that assumption clearly isn't true as their two templates (expansion and thrust) cannot fit the curve I've posted together with constant heating and steady thrust. This combined with the fact the control isn't a true control for thermal expansion is a problem.

They're going to have to do a better job next time. It would help if they published in a real physics journal and got better review.
>>
>>8850186
>Sounds useful.

Lol, retard. If it works it produces something on the order of microNewtons of thrust per Watt. That's fucking useless.

>>8850194

>>8850217
>microNewtons of thrust per Watt.
mN is millinewtons
milli - thousandths
micro - millionths

>It's very similar to the paper that was leaked online earlier this month and, most notably, shows that the drive does indeed produce 1.2 millinewtons per kilowatt of thrust in a vacuum:

>>"Thrust data from forward, reverse, and null suggested that the system was consistently performing at 1.2 ± 0.1 mN/kW, which was very close to the average impulsive performance measured in air. A number of error sources were considered and discussed."

>To put that into perspective, the super-powerful Hall thruster generates force of 60 millinewtons per kilowatt, an order of magnitude more than the EM Drive.

>But the Hall thruster requires propellants, and that extra weight could offset the higher thrust, the team concludes.

>Light sails on the other hand, which are currently the most popular form of zero-propellant propulsion, only generate force up to 6.67 micronewtons per kilowatt – two orders of magnitude less than NASA's EM Drive, says the paper.

Only if your spacecraft is 90% engine and propellant in mass. That is not the case for any ion powered spacecraft in real life.

>>8850239
>only generate force up to 6.67 micronewtons per kilowatt
Solar sails don't require power from the spacecraft at all. Talk about misleading numbers. EMdrive on the other hand (if it wasn't bullshit) would require solar panels. That adds mass which as they pointed out above can kill the advantage. What hypocrites.

That's not how it works in science. If you want to claim X is true it is your responsibility to convince the community that is so. Burden of proof. Firing out some half-baked experiments does not cut it when there are still many systematic effects that they have not tested.

I have an experiment almost setup that is trying to measure a force with this mechanism. I probably won't get everything finished prior to leaving for my post doc, but the facility where I am going already has the experiments set up and in much better condition. Hopefully we can measure the force within a year...

Theoretically, I am dragging some ass. I have 4 papers backlogged that I have to finish prior to typing up this idea. This should be around a year as well...

What I am really excited about is the place I am going has all the facilities in place to get this thing off the ground...

The bottom line is this; If the idea works, and my post doc will have all the things necessary to check it, then it is gonna get done. There is a valid scientific pathway, based on very conservative(realistic) assumptions, towards making this thing actually work...

we shall see...

No. If at the end of the day the paper doesn't convince you then it doesn't convince you. Peer review just means it probably isn't isn't filled with utter crap but it doesn't mean it isn't deeply flawed. Go to a journal club and see how many bad papers are published.

The flaws in the methodology are clear to see. The fact these haven't been dealt with yet says they haven't proven it actually works as claimed.

>I've yet to see anyone bring a peer reviewed explanation of where everyone working on this is going wrong.

You don't peer review criticism of papers. Only very occasionally will anyone publish a reply to your paper but only if you really annoy them. Given that this paper wasn't even published in a physics journal it probably won't garner much attention. Again it's the papers job to convince the reader.

>Even a rough outline of how flaws in their methodology could result in apparent thrust of the same magnitude would be welcome.

Hello Anon.
your level of intellect astounds me.

How did you learn so much about math to get to the point where you are right now? What fields o math are you using to make this thing? How will you get the materials and stuff to develop the actual device? I have been really interested in learning enough math to do cool space and sciency shit like this but I am not sure where to start.

At the moment I have books on Electrical Engineering, Calculus, Physics, Quantum Mechanics, and Mechanical Engineering. I chose those subjects because they are mostly what Nikola Tesla knew. I plan on researching the living fuck out of it all as best as I can.

Thanks for the link.

Hopefully we'll have confirmation either way soon.

China's shuttle docked the other day and maybe it was on board.

I did double major in physics & math during my undergrad and then quantum field theory in curved spacetime in grad school...

The math that I am looking at in terms of the emdrive is quantum, e&m, and some optics... its qftcst that is giving me the most intuition about it though...

If you are looking at playing around with "mad scientist" type stuff, I would say get a bit of general relativity under your belt (this helps with intuition), and then study as much quantum as possible (from beginners to advanced, stay away from strings and supersymmetry), a little condensed matter and nanoscale stuff, and electrical engineering (this makes you think practically)... basically, start thinking about some weird ass quantum + gr stuff and see if you can engineer something similar in condensed matter or EE... Essentially, you are trying to find a nice balance between the most far out shit that can be played with using laboratory techniques...

For making the device, it looks like basic materials will suffice, i.e. evacuated metal cylinders... What is important is maximizing the effect, but that is were the experiments come in... The experiments are deal with the manipulation and control of electromagnetic radiation (sorry for being vague)... If the experiments have good results, and I got a good theory behind it, then I will try and maximize the effect.

I have basically studied a shit ton of quantum. I got a little bored of just doing theory and started to redpill on tesla... Then I saw the emdrive and it looked like my chance at doing some tesla tier science...
>>
>>8858077
That's fucking awesome. Really interesting shit here man. I'd love to learn more about mad scientist type stuff.

So, my list on subjects to study now is:
>Electrical Engineering
>Calculus
>Physics
>Quantum Mechanics
>General Relativity
>Condensed Matter
>Electromagnetism
Lots of stuff, should keep me nice and busy for a loooong time. Just what I want.

Also, what about Mechanical Engineering? It was on the list I had in the post you replied to, but so far from what I've read on it it seems ME is just a meme.

Earlier in the thread you mentioned you could produce the EM drive for personal use. Are you implying if you want to, you could make some fucking ship or something all on your own with this?

Or is space travel simply a single use of the EM drive?

I am pretty sure the more fields you study, the more you will start to think of ideas. ME is solid but might be too "mechanical" for this type of stuff. The only fields I know of that are meme tier are strings and supersymmetry...

I would also emphasize studying bound states in quantum... particle in a box, harmonic oscillator, and other potentials, as well as approximation methods for bound states... That is where the majority of my intuition comes from now that I think of it...

I can not currently make one... My situation is as follows; I am currently working on the emdrive theoretically and doing very basic experiments, I am going to a place with all the facilities necessary to pin this thing down legitimately (i.e. found out once and for all if it really works), and where I am going has infrastructure in place to help scientists develop start ups based on newly discovered tech (and most importantly protect them for a small piece of the pie of course)... So, if it works, I am gonna try and start a spacex/weylandyutani type company and crack space wide open...

this does imply making "space ships". moreover, the technology involved seems that these things are legitimate garage band space ships. Look at the emdrive, its literally a microwave oven strapped to a capped bucket.

Fundamentally this device converts electromagnetic energy to kinetic energy so you can make all sorts of fun little engines with it, but I would imagine the most novel would be a "rocket" engine like the em drive...

Just to be clear though... what I am claiming is this; There is a valid (as in backed by tier 1 published literature) path that I claim as a hypothesis as to how the em drives works, I am following that path to completion, I am going to an institution that has the facilities to accomplish this, and if it works I am going all in and starting a business.

I WILL see the hypothesis to completion and find out if it works... goodtimes :)

If its up to me... I can envision a working model capable of leo tests within 5 years...

What makes this idea attractive is that you don't have to worry about mass as much as with rockets... you could strap an airtight safe to it and fashion a steering wheel and go to the moon... its a game changer (if it works)!

If your theory is correct, what kind of thrust are we talking about here?
>>
>>8858749
I really don't know much about building machines and what not. Unless Electrical Engineering covers it.

Even then, doesn't Mechanical Engineering cover generation of power? So I'd need to learn how to power the shit I make from EE?

Also, you say garage band space ships.

It probably is my lack of imagination and machine building skill, but I still don't see how you can home build this type of shit without massive backing and stuff. People to build components and sophisticated stuff. Then again, Nikola Tesla made a bunch of cool shit.

Like yeah, the EMDrive is a microwave oven strapped to a capped bucket, but what about what is INSIDE that shit? That's the part I'm stumped on.

Shit, Nikola Tesla is my main inspiration for getting into this stuff. The motherfucker was making a ray gun in his basement. And was making wireless electricity. That's fucking awesome.

It doesn't, any amount of thrust coming from it has been confirmed as experimental error.

>>8858873
I don't know that yet... I imagine it will depend on lots of factors such as wavelength, geometry, intensity, etc... ideal would be atleast 1g for some realistic spaceship sized mass...
>>
>>8858939
Actually generation of power is actually a good thing to look into... good call...

At the end of the day it is unlikely that it could be built in a garage. There will probably be some pretty dangerous electronics (high voltage, etc.) that would need serious consideration while constructing and there would definitely need to have some investment. I just meant that it wouldnt take a nasa scale effort to make it... Barring the need for exotic materials, it would estimate a cost of ~10 million to make something halfway decent...

I do have an idea for how it works, but I am not going to say until i publish (I really dont want to sound like a pretentious ass). My idea may actually be different but is "inspired" by the emdrive... I will be sure to make a thread here if/when it gets published...

nikola tesla was a god damn savage!

I am the typical age of someone finishing a phd... perhaps 3 or 4 years older than the average actually (I transfered schools and then had to wait for a post doc). I screwed off bad in grade school (skateboarding). I just applied myself when I got to college to catch up. 100% hard work, no question about it.

I liked physics when i took it in high school (it was the one class i wouldnt skip). When I got to school I just followed what interested me and that eventually pointed me at quantum field theory in curved spacetime.

Thank you so much for the information. I'm looking into getting a lot of books now.

Speaking of books, are there any good books in particular that have stood out to you as being fantastic in your line of work?

At the moment, I don't even know all of Pre-calc, I already have Algebra down so I'm learning all I can about Geometry, then Trig, and then I'll start on my Physics books, so I'm just trying to get a good library I can work my way through.
>>
>>8859124
well propulsion is one thing, what about the vacuum of space? how will the ship survive that? wont you need advanced ship building shit for that?
>>
>>8856230

You still need to put the electrical energy into the thing to get it up to relativistic velocities in a vacuum

That will require lots of energy

>>8858453
Nope. I'm going to double atmospheric methane in a few years. I'm not stopping at double either. It was a nice try but ultimately a failure that must be contained.

>>8847289
Magnets and Gamma Radiation.
>>
>>8859006
yes but which paper?
also, was it proven experimentally or did they examine the data and draw the conclusion that it was anomalous instead of thrust?

>>8847289
it doesn't
>>
>>8859265
get crackin on that calculus bro... :)

griffiths e&m and quantum are pretty good. I used Morrison for quantum. There are solution manuels for griffiths too so you can roll through them without getting stuck... for qftcst the best intro hands down is mukhanov and winitzki and the standard, more advanced, reference is birrel and davies... for gr proper, I would get general relativity demystified and carrols book... for qft i say good luck cause it is a shitshow no matter what you do :) ...

if you are starting from the beginning with physics, I would recommend getting "REA problem solver's physics"... it has worked solutions starting from adding vectors all the way up to modern physics...

the fastest way to learn these things is to get books with solution manuels, let that guide book selection...

repeat after me: mother fucking landau lifshitz! If you work through those books (and they are accessable) then you will emerge a savage ass russian style mathematical barbarian. Those books are amazing.
>>
>>8859371
this is true, but a lot of the main difficulty of constructing spaceships is keeping the weight down. If the weight requirement is relieved, then you can literally take a scuba tank for air and jump in a air tight safe...

This is a bit hyperbolic of course, the point is that this type of engine solves a lot of problems that required extremely advanced engineering to overcome... How much it simplifies the design is yet to be seen but I can imagine that it will make things very simple.
>>
>>8861135

Well my book selection is coming along nicely. I gotta add your recommendations now.

Do you get paid to research this stuff by the way? This shit is going to take me forever to work through.

Damn. If I could find a job like that I'd love it. I fucking love learning stuff. So far the only thing I've been committed to career wise is just Comp Sci since that atleast lets me learn new technologies to keep up with the line of work. I'm starting to consider majoring in Mathemataics or Physics now though.

computer science is not a bad investment... quantum computation is becoming one of the most active fields in physics. I would bet money that quantum computers will take off soon in a big way...
