This device can accelerate any particle that has mass and thus this device could be used to accelerate dark matter. If there is 8 times more dark matter than regular matter it would mean that this device would be much more efficient. An analogy would be the difference between a rocket in space and a boat propeller in water.

One issue though is that both the most common particle mass and the average velocity and approximate direction must be known for the device to work. Without this information the device will just vibrate as the wave falls in and out of sync.

Due to interstellar gas pressure the dark matter in the galaxy can not stay in sync with the solar system. This means that the dark matter is likely in a disk along the plain of the galaxy and moving at the average rate for our given distance to the center. The thickness of the disk is also important since if it was really thin this device would be very efficient, but only for the short amount of time that we are crossing the plain. If the dark matter is in a wide band then the efficiency would be lower, but it would work most of the time.

I have come up with a way to use the first part of the crystal to orientate the particles. This means that I no longer need to know the particles direction and speed. This is good since it's impossible to know both at the same time. However, this new section requires knowledge of the particles exact mass in order to tune it. I am hoping that further understanding of what kinds of particles make up dark matter will allow this device to be tuned.

It is possible to create a thrust without an apparent thrust by accelerating particles that do not  normally interact with matter.


 The device is very similar to a traveling wave tube amplifier. A RF field is send down the length of the crystal to create an acoustic wave. This wave intersects a row of atoms at slightly faster than the speed of the particles that are being accelerated. (Note: this does not mean that the wave is traveling faster than the speed of sound, just that the wave front is at an angle to the crystal lattice)

The crystal is must also be cooled in order to prevent normal atom movements from interfering with the effect.

When A particle is aligned with the crystal and the wave it can get a boost or buck depending on its phase.
If a particle gets a boost it cant go faster than the speed of light, however if a particle slows down it will get scattered. Thus given a large enough crystal the accelerated particles will dominate. Now since the particle is already going near the speed of light you do not actually increase it's speed, however you do increase it's effective mass.

The effect is similar to the way traveling wave tube amplifiers work. except in this case it uses the fact that neutrinos have mass.
Or you can think of it as changing the local gravity field around each particle.

In order for this to work, you must know the speed and direction of the particle. The exact type of particle does not need to be known; just the direction and velocity are needed.

neutrinos from the sun
The sun produces lot's of neutrinos. This would make a good place to start since both there direction and speed are known.
Note: It's not necessary to know the exact position of the neutrinos, just the angle from where they came from.


The exact crystal used is unimportant provided it's dense and has a uniform structure.

Different crystals have different critical frequencies where the effect no longer works.
The frequency is dependent on the both the structure and the temperature.

Acoustics and magnetron

The trick is to acoustically excite the crystal so that the pressure wave intercepts the atomic structure at a precise angle.
The angle is the speed of sound in the crystal vs the speed of the particle. Note: This will require an adaptive controller.

The higher the frequency the greater the effect, however you must be able to control the frequency and it must spectrally pure.
This currently limits us to the microwave band.
