We are witnessing the development of your theory in real time, like a reality show(interesting to watch
)
>Like gravity, we want a small acceleration and large mass falling down the gravity well
I've been reading the posts between Warp and Rodal. And this sentence sums it for me. Its a mystery.
What the heck has gravity got to do with emdrive?!
A large mass falling down a gravity well? emdrive?!
You discuss several of the fields in the cavity, but to what effect, you never seem to go anywhere with it. How do you propose the activity in the cavity is resulting in thrust?
Actually, you have to read my work to understand it.

The only difference between what was written then and what we are discussing now, is that in the Damping Factor, I am now proposing a gradient in the decay time of the stored energy rather than a gradient in the frequency, since per Maxwell's equations, the mode frequency is a constant throughout the cavity. I'm working on the re-write for journal publication, which will streamline this whole presentation.Perhaps mode frequency is a key parameter. Will test this out next year. Displacement forces died out when my magnetron failed to approach resonance. U might want to keep this option open just in case...


Yes, the energy density, and the Maxwell stress, and the Poynting vector are all oscillating at 2 omega where omega is the frequency of the electromagnetic fields. The E field at omega produces an electrostrictive strain (and hence an elastic stress) on the HDPE or the PTFE also at frequency 2 omega.
So what is missing for the Mach Effect in the EM Drive is a force acting at omega. Both the electromagnetic forces (Maxwell stress and Poynting vector) and the electrostrictive forces are all acting at the same frequency 2 omega.

Both the electromagnetic forces (Maxwell stress and Poynting vector) and the electrostrictive forces are all acting at the same frequency 2 omega.That's not too difficult to arrange with a statically charged dielectric. Insert a low-loss (so as not to lower the Q) dielectric with surface electrodes and apply a DC voltage there. In a precharged (nonzero static electrostriction) dielectric the electrostrictive strain from the AC component will transition from 2*omega to 1*omega. If the DC voltage component can reach the AC peak levels, the 2*omega electrostrictive term will disappear completely and fully convert into an 1*omega term instead.

Ok I see now why I couldn't understand Rodal's and Warp's exchanges.

> assert that an unknown phenomena is due to creating its own gravity via this new theory of gravity, even though by conventional theory it has nothing to do with gravity
So not only are you trying to explain an unexplained thrust phenomena, you've also trying to explain gravity, which has never been explained despite millions of man hours spent on it over hundreds of years.
Shame that for the last 200 years, scientists didn't approach every new phenomena like this. /sarc
As a new member to the forum I have to balance being nice vs stating the truth as I see it : So far I've been nice, but now I have to say this :
WarpTech's approach to explaining emdrive is profoundly unprincipled. Mixing 2 completely unrelated unexplained parts of physics : emdrive thrust , and gravity ; and trying to explain them both at the same time just stinks of the unholy culture of string theory, super string theory and m-theory - that is : trying to explain everything in one go ; all now widely excepted to have been an absolute waste of time.
Its a grab all and explain all attempt in an effort to be a super-Einstein, to create a universal theory, and is diametrically opposed to a sensible scientific protocol : divide and conquer \ try to avoid tangling things up.
Cooking up mad theories that hoover up unrelated phenomena and try to explain them all at the same time in a vain attempt to be a superstar has been a plague in the theoretical physics community, holding it back since WW2.
I'm aware of internet forum culture that has grown in the last 15 year. That is : if you have lots of posts then you are a PhD and very wise, but if you have only a dozen posts, you are considered a teenager at school. In fact I'm old, have a BSc in physics and have maintained an interest in physics all my life.
Board admins should allow a degree of liberty for members to discuss a new theory, but mixing gravity and emdrive into a mad theory should trigger a red-card by any standard. That it doesn't is just indicative of the NASA \ string theory culture of allowing mad theory to flourish around any and every unexplained physics. Its almost like the contrary is true : you'll get banned or ignored if you DON'T put forward a mad theory. If I was board admin I would not allow such mad theories here.
bah. I hope Rodal's theory isn't as mad as Warp's.
Let's have it Rodal.

or not.So not only are you trying to explain an unexplained thrust phenomena, you've also trying to explain gravity, which has never been explained despite millions of man hours spent on it over hundreds of years.

> I do not see why it would be particulary mad to mix gravity and Emdrive.
If I'm the only one on this forum that sees its mad, then I wouldn't be surprised. There is a culture for it, and within that culture, it is acceptable rather than seen as mad.
If WarpTech was to expand his theory to include a few dozen other unexplained phenomena in other fields of science, it would be seen as a good thing in this community.
If you'd done any engineering then your divide an conquer principles would prevent you from trying to solve 2 unexplained problems at once. Only when both problems are mastered, can consideration be given to integrating the 2 theories. This has always been the way in science and engineering, and always will be. And I repeat, trying to go from a list of unexplained unrelated phenoma to a generalized theory in one step has always resulted in failure... But the lure of being the worlds 1st super-Einstein overcomes any and all rationality... so we are stuck with 1000s of theorists trying to do 2 steps in one, and failing, while everyone else applauds them.
Except me.

Here's some theory I think is central to emdrive :
Why doesn't a 100 Watt light torch give a reaction force ( kick back ) similar to a mechanical device with a power of 100 Watts?

An example of mechanical 100 Watt thruster is : A man throwing 2kg mass projectiles...accelerate the man in the opposite direction...
But the kickback from 100 W light torch would be effectively zero by comparison.
..only a tiny fraction of the energy in light is as mechanical energy \ momentum. Most of it is stored in a EM wave which is lateral to its motion. In other words, a photon is like a thrown grenade, its kinetic energy is insignificant in comparison to its stored potential energy.
...a light torch does not give a significant kickback, and why an object being exposed to a light doesn't experience a significant kickback. Energy conversion between mechanical and light energy is lateral to the direction of travel of the light.
...
Well that's the end of this line of thought. Its not specific to emdrive. Its just a theory on how to convert light into motion, without using a propellent. It maybe that emdrive is somehow using this theory.

I think this problem does have an all mechanical anology : converting the energy of bullets into slow coherent motion; this may give us insight into emdrive...
... The problem of collisions at high energy momentum ratio
...
Dough Boulder
One simple improvement it to make the boulder soft, like dough. This way, at least the bullet's energy isn't used to particlize and scatter the bullet or the boulder. The bullet decelerates slowly and comes to rest intact.
...A slightly different, more hypothetical and fanciful idea would be to have the bullet collide sequentially with gradually slower moving small objects.
...Converting this analogy over to emdrive : step 2/2
So can something like this be happening in the emdrive cavity? Yes.
Starting with lightwaves ( the bullets ), we need to have something that will act as the set of sequentially slower moving objects. There is only one object that can be : electrons - yes a cavity full of microwaves with conductor walls will have a few loose electrons in it- electron plasma. Starting at one end of the cavity, light is passing its energy quite efficiently onto fast high energy electrons, which pass on kinetic energy to low energy electrons, until the lowest energy electrons pass on KE to one of the end plates, which absorbs the energy more efficiently as KE than if it was just being hit with the unaltered light ( initial high speed bullets ).
Lab experimenters may want to look for a gradient in electron energy within the cavity.

Isn't there just a slight, tingling doubt somewhere in back of your mind, or are you sure you've just circumvented a rule of science and engineering thats as old as history?
