Propulsion system works -- Nobody knows why?

Well it turns out the Emdrive does produce thrust. The problem is that the engine appears to violate the principle of conservation of momentum.
So, it has been independently shown to work, but nobody knows exactly how it works. Some unknown quantum effect perhaps?

In this case, these scientists modify their preconceptions and say "since we see this in the end, the beginning MUST be this way because that's what they must be to fit our theory"
Some decades ago, a claim of an 'antigravity generator' was "demonstrated" using simple tools like an electric drill, some swinging weights and a bathroom scale.
Turns out, it didn't meet any claims. It seems that the only thing really discovered was that when a bathroom scale "weighs" something that's vibrating all over the place, it's nowhere near "accurate."
I'll wait for replication, thanks, but it's either a fraud OR there IS something 'doing it' that we don't understand YET.
"Consensus" is what kept the Geocentric "Theory" alive for a lot longer than it deserved.
Einstein postulated a whole raft of Theories, some of which took many decades to be verified because 'instrumentation' couldn't even do experimental measurements accurately enough!
"Loose rules for outcomes"??? No! A theory describes the expected result from experiment and subsequent measurement. When the experimental results stabilize close to some 'final value' "Scientists" eventually decide that it might not be worth the time, effort or money to wring that extra few decimal points out of the answer. Actually, the folks funding their research have that influence. Pure research is a "forever goal."
Einstein in 1927 argued for those rules of science. Bohr argued against them. He, being the bully that he was, along with Heisenberg, Pauli, and Dirac, shouted everyone else down until he got his way, and it became "the consensus". Schrodinger, Einstein, and deBroglie fought them, but ended up losing the fight.
And so here we are.
Anyhow, in a regular wave cavity the photons just travel in zig-zag paths. Remember the angle of incidence thing? I don't think the design has or requires the photons to bounce back and forth between the "reflectors" parallel to the line of thrust, like what happens in a laser or maser.
Also in a regular wave cavity, the photons just bounce around until they absorbed. They never escape. Even if they did, they wouldn't be going in any particular direction.
B.T.W, engineers use resonant cavities in things like tv transmitters, cell towers and radar where the power output would fry any semiconductor. But the ones they design all have uniform cross sections. Designing something that shape to resonate is really out in the weeds.
So, classical electromagnetic theory just predicts the thing will sit there and get warm.
Lastly, back to Rand and who does what in our society. It is up to the boys at S.P.R. ltd. to prove it works. It's their baby.
The Chinese say they tested the Idea and said they got it to work. That got the attention of the guys at NASA. They probably assigned their least favorite "Quentin Daniels" to go look at it and he found something he couldn't explain. Hopefully he volunteered, because I don't think that that would be a plum assignment (you could come out looking really foolish if you screw up). At least the guy says he needs to run more tests.
That's why they're called 'theories'! That's what "science" is really about... creating 'theories' to try to explain and understand phenomena observed in the world around us.
If a theory proves, through experiment, observation and repetition to ACCURATELY describe and PREDICT some phenomenon, it becomes 'accepted' or even called a "Law."
If observation and attempted replication show that the 'theory' does NOT accurately and repeatedly predict, it's discarded or modified to see if it can fit what IS observed or predicted.
What 'theories of quantum physics are correct' today may be changed or rejected OR proven to be accurate in the future.
THAT'S what science does. To argue the veracity of a Theory is silly.
Many 'theories' have been modified or proven OR disproven as new information has been discovered and/or measurement techniques have improved over the centuries.
Please consider thinking about "theories" as 'today's explanation as best we know or understand it TODAY' and not as some cast-in-stone Truth Forever.
If the predictive value of a 'theory' is found to not be accurate, it's wide open to modification or rejection.
If they claim it "works" but they don't know how, then it simply doesn't work.
The quote mentioned is from Jeremiah ...who had capricious patenting. God was reassuring him that nothing would change between their relationship.
Jesus operated in the realm of the sub-atomic. That is how water is turned to wine and food is multiplied.
Eventually we humans will find a way to do the same.
I think this is all very exciting.

Did you notice the spelling in The Book?
If it hasn't been scaled up and replicated and proven, it's just Bad Science.
The scientists who founded modern science did so because they were, *gasp* Christians, and in their knowledge of the Creator, they knew that He was unchanging and utterly reliable. Therefore, they postulated that his creation may also be reliable and not based on the "whims of the gods" as was widely believed at the time.
Now, we have a whole new voodoo science called quantum physics, going back to the days where things are non-deterministic... it's stupid. I'll tell you something... God does not play dice. Einstein had it right to begin with on a lot of these things, and then just went off the deep end.
virtual mass, resulting in a translation of energy
received into energy projected. through a converter.
very fascinating, sir!!! -- j
I think it does expel energy, which means if you made a precise measurement it expels mass.
