Well the guy who invented it seems to care or he wouldn't have written about a supposed theoretical justification. The guy would seem less cranky if he was honest and said "I have no clue what's happening, please investigate these experimental results".

I'm not upset about this situation at all though. If the memedrive actually works I'll be too excited at the possible free energy utopia to care about anything else and if it doesn't I'll just have another reason to make fun of engineers (like Electrogravitics).

Should this board just be deleted for being so utterly and completely rekt?

This thing will produce new physics, just very mildly new physics.

The stuff in the paper is nonsense. The thrust it produces is fairly minuscule. To be produced by propellant would require nano-grams of exhaust. This would make it extremely challenging to actually observe as a weight loss.

The thing has thrust because of nano-grams of exhaust, that's probably the reality, but the new physics comes from explaining why it's producing this exhaust, which is less clear.

>>8488388
>they exist in a separate frame of reference

Wew lad.

>>8488736
UNLIMITED POWER means that literally anyone could destroy the earth.

Wait, why is everyone assuming that this either doesn't work or is infinite power? Isn't there a much more likely possibility that this is some form of directly converting the energy into thrust, à la photon engine except much better?

>>8488873
>directly converting the energy into thrust, à la photon engine except much better
is what it's supposed to do.
Infinite energy immediately follows from this because just accelerating continuously will lead to the craft gaining more kinetic energy than you put in to power the device (rather quickly, actually). From that point on you can do whatever you want with the craft to get energy back out (like crashing into a wall or something).
The reason this is not possible with a photon rocket is that the energy to thrust ratio is exactly low enough that the gain in kinetic energy would only offset the energy lost by creating the photons if you were already travelling at the speed of light.

>>8488896

Why? (To any of your post)

You're assuming that if you provide it a constant amount of power it will produce a constant acceleration, regardless of velocity and reference frame, yet I've seen nothing that hints at that.

>>8488940
Say you strap tons of them to a dynamo, they take less energy to run than they produce so you would just be generating more power indefinitely, assuming it was in space.

>>8488965
Not him, but are you saying that if it were set up right and not used for space thrusters and some kind of "energy factory" in the vacuum of space, you could literally make a electricity goes in - more electricity comes out system only using a dynamo? Is there anything in the paper that supports that?

Maybe I'm just reading wrong

>>8488970
I think so, because it produces thrust it's not like those perpetual motion devices that would require 0 friction to function. It might take time to become efficient while you wait for it to accelerate, but I don't know [spoiler] I'm not a rocket scientist [/spoiler]

>>8488940
The acceleration will not be constant when seen from a stationary observer. This happens because of the finite speed of light: the acceleration will decrease the faster the craft moves (for a stationary observer!) since it cannot reach the speed of light.
What is assumed to be constant is the acceleration measured by someone travelling with the ship: if the craft stops accelerating and moves at a constant velocity, a crewman on the ship then has a perfectly valid reference frame in which the drive is motionless and not affected by outside forces, the same situation as before the ship started travelling, and should get the same results when measuring the drive's properties. That is why it's not expected that the energy to thrust ratio changes depending on how long you accelerated.
This of course assumes special relativity is true and there is no preferred reference frame. https://arxiv.org/pdf/1506.00494.pdf actually does the calculation and also has some discussion.

>>8491035
>>8491066
>>8491090
Dark matter explains the observations without any changes to the well established GR nor the extremely elegant standard model of cosmology. Matter that only interacts gravitationally is not particularly implausible. It's discomforting, which is probably why you feel so strongly about it, but by no means something that is a lot to buy. Distributions of dark matter can be observed fairly well via gravitational lensing. It's not like every piece of baryonic matter is shielded with dark matter in the same way (which would indicate a strong correlation between the two). Also it's not like nobody has ever doubted dark matter, it's probably the one established idea in physics that is criticized the most. There are countless attempts at correcting aspects of GR and cosmology to account for the offset created by dark matter. The problem is, none of those attempts comes even close to fit as well as dark matter. All of them usually only explain those aspects that motivated the corrections, but not the whole range of phenomena.

>five invisible particles for every visible one.

But anon, all particles are invisible. We only ever see their effects. I mean has anyone ever seen a nucleus? No, but we can preform a scattering experiments and show that an object exists that has the properties that define a nucleus. It's the same here, sure you can't [math] see [/math] dark matter (since it doesn't use the em interaction) but you can do some experiments that show an object with all the properties of dark matter must exist.

>>8491090
>I have this great theory that is a vast generalisation on an existing theory.

Do you really think that we should abandon an incredibly successful theory such as GR just because it requires the incredibly small assumption that there is a particle that only interacts via gravitation?

>>8491455
>epicycles explains the observations without any changes to the well established Ptolemaic model nor the extremely elegant model of heavenly spheres

>>8490672
To be fair there is a more advanced theory that claims the momentum is transferred from the outside system through a long standing hypothesis on relativistic pressure

>>8491126

A supposed violation of momentum conservation may need a little more evidence than this. If further investigations really does confirm the findings, then I'm surprised, but excited for new physics.

If it were up to the mainstream, this experiment would have been shouted out of existence to keep the status quo. As it is, research is hamstrung by the naysayers expending more energy on shutting it down, rather than opening their minds to the possibility that something's going on.

Physics is a broken hodgepodge of confused esoterica trying to integrate with the sublime purity of the QM model. You'd think that specialists would be excited at the possibility of insight into the gaps.

that in which there is no relative redshift of the CMB

Shawyer's been working on this for ages,he must have some major funding,but the thing that annoys me is he could easily afford to send a small emdrive into space for testing-you can book a small satellite launch for a few tens of thousands of dollars,pocket change in the aerospace world. Why doesn't he just send one up and finally confirm this thing one way or another?

dude, stop

space mining is already economical for things like platinum, the key thing is re-usability, if you can get a fuel depot in space supplies by grabbing ice and shit that's up there and keep your fleet powered that way, you're set, operating costs will fall rapidly with economies of scale. Pretty soon, you can bring back even less precious metals and make a profit.

Assuming you find a magic asteroid that has tons of platinum...
More aggressive exploration for it on earth would give you better bang for the buck

The only advantage of space is dodging environmental regulation

So I have a question: if this is real, it would be pretty huge discovery. Wouldn't you publish this in something like Phys. Rev. Lett., Nature or Science? Why go for shit journal with impact factor of barely 1 that no one ever heard of (and take a fucking year pushing it through peer review)?

>>8497174

You know all that water in the ocean? It can be desalinated. We don't do it, because it's fucking expensive -- a whopping 81 cents per cubic metre.

Can you get water from space at less than 81 cents per cubic metre?

>>8496649
Resources which are rare on earth but common in other celestial bodies means there can be an economic incentive for asteroid mining. For example, tritium and other rare isotopes.

>>8497708
>For example, tritium and other rare isotopes.

Pro tip: just because it's rare doesn't mean there's a market for it. Take tritium, commercial need is about 400 grams per year, at a cost of $30,000 per gram. So you're looking at $12,000,000. Barely enough to off set launch costs (current average price to Send something to geostationary transfer orbit is something like $25,000 per kilogram, say you send 4 men weighing about 70kg each then you're already looking at about $7,000,000).

As long as it can still be used for stuff of course not.

You just have to realize its not actually whats going on, and only a hand way to look at things in some situations. Like geocentricity.

This is the problem, scientists think they are finding truth, science has nothing to do with truth.

>>8488388
Apparently thrust has a relation to the quality factor of the resonant cavity. The Q factor can be made quite high with superconducting technologies. Anyone have more intimate knowledge of this?

what if

it shoots DARK MATTER as a propellant

>>8498500
If the retarded physicists call it dark propulsion, I'm gonna puch someone.

What came out of that EM drive project?

Lots of calling names and swearing by Newton.

So if you think it's impossible, what do you think is the error source in here?

On one hand i don't think NASA would be so retarded to make such an error. On other hand I think a proper test should involve self contained, battery powered system. Otherwise, twisted cables or not, but if few miliamps can move a few cm long wire strand, 80w in and out make it no way a closed system and magnetic effects are bound to happen.

There's quite a few different reasons why it might not be as advertised, not that these reasons ever make it into some pop-sci shit.
Here:

We see Martin Tajmar testing memedrive, take away point they detected thrust in one direction...they measured something. Then they turned it one it's side and still measured thrust in the same direction as before. Clearly it's actually producing thrust.

After reading the paper and some criticism on the web I'm fairly convinced the paper shouldn't have made it though review. What they have here is thermal expansion. They should have done more tests for this but they didn't.

Depends entirely on where that water is going. If Space Colonies become a thing that is where the price of water will be much higher and space mining will be viable.

>>8501933
They argue in the paper than the curves they see are a superposition of thermal expansion and thrust. Problem is they decompose the curves using a model which assumes constant heating which clearly doesn't match the example shown even combined with their thrust template. Their model doesn't fit the data (they don't admit it but it's obvious from the plot) and it's that model they use to claim it isn't all thermal expansion. They need better testing, they've done too few tests to claim anything conclusive.
