As above, so bellow
Particles do.
OK, so it is other way around. Particles are deflected around, but radiation goes streight in? Can you please be more specific ...

no, i don't understand the disconnect. ALL geodesics through the warp scatter everything to the sides of the craft.OK, so it is other way around. Particles are deflected around, but radiation goes streight in? Can you please be more specific ...
This guy seems to be on to something...
Gravity, Gizmos, and a Grand Theory of Interstellar Travel
MEGA (Mach-effect gravitational assist)
Woodward’s MEGA drive is different. Instead of propellant, it relies on electricity, which in space would come from solar panels or a nuclear reactor. His insight was to use a stack of piezoelectric crystals and some controversial—but he believes plausible—physics to generate thrust.

Matter currents. Mass has a particular meaning for those few of us who understand relativity as a theory of invariance. For us the term relativity is a reference to it being a theory about how coordinates "relate" in a universe where the laws of physics do not depend on frame, ie invariance.Q for @waitedavid137 ... Is it fair to say that warp drive works by creating mass currents that then cause frame-dragging and that frame-dragging is converted into linear motion?

I wouldn't get too excited about this one. Woodward has been making these kind of sensational experimental claims since NASA's Breakthrough Propulsion Physics program 20 years ago, when I first looked at his proposal.This guy seems to be on to something...

Neglecting tidal forces, free-fall is an inertial frame of reference; the Space Station is in free-fall for example.I think that's the same thing as Biefeld–Brown effect, only Brown was doing it with very heavy capacitors and high voltage. He got movement as well, just before WW2. Some aspects of it are similar to @waitedavid137 described in his original YT video. Basically when one ramps up voltage really high, into billions of Volts, he starts bending space-time and creating an acceleration field (aka gravity).
I am not a physicist, but the only true way to test this is in a non-inertial frame of reference, or in a free fall. At one point in that article, he mentions that they are using a torsion scale and some electrical resonance. Well, torsion scale has, however small, a finite mass and thus inertial. On other side his stack of piezo electric disks produces a kick each time he sparks high voltage into it. If you get resonance and amplitude of these voltage kicks just right so they match inertial mass of torsion scale, you got the "fake" thrust. It's a different story to try that in a free fall in orbit, without torsion scale, friction or any other parasitic forces.
I had a similar idea with plunger and solenoid, but I just didn't know how to get rid of any time of support with friction etc. They really need to take it to Space Station and see if it will move inside it's long corridors.

The operation of his device depends on something he calls "transient mass fluctuations," which have never been observed and almost certainly don't exist.

Woodward's hypothetical operating principle is unrelated to the hypothetical Biefield-Brown effect. Woodward's experiment basically consists of two bodies of matter joined by a spring, and he thinks that he can increase the mass of of each body by a little bit (by storing mass-energy in a piezoelectic material) at the right moment of each oscillation cycle, so that the pair of bodies will push and pull each other forward in a linear manner. It's a nifty idea, but it probably belongs in the Museum of Unworkable Devices.
