OK, that's a good point. But they seem to be able to form beams out of whatever fields they have and lift cars, cows and people.
All fields can be collimated to an extent, so it’s not surprising that they could produce gravitational and other kinds of beams. There have even been some advancements in creating a kind of “tractor beam” using lasers:

Sometimes UFOs are funny. There was a case where a farmer was hit on a forehed, like with a fist, but from 50m (150ft) away.
Haha, that is funny. It’s easy to imagine that other forms of intelligent life would also have a sense of humor/whimsy.
OK, OK, are we talking here about dipole (like in magnetic field) or two opposite particle charges, like in electric field?
It’s exactly analogous to electromagnetism, in the weak field limit anyway (but gravitoelectromagnetic effects scale nonlinearly, unlike electromagnetism, so in high-field regimes the effects are stronger).
So think of it this way: ordinary mass-energy possesses a positive “mass charge,” which acts analogously to an electrical charge. That’s the basis of Robert Forward’s toroidal gravitoelectric dipole generator (which is what it sounds like you’re describing – that’s one of my favorite concepts). If you have a toroidal ring, with a “mass current” flowing around the ring in a spiral (just like the electrical current flows around the winding of a toroidal inductor), this establishes a gravitomagnetic field within the toroid. But that has no effect on a stationary mass. To exert a force on a stationary mass, the mass current has to be accelerating. When that’s happening, a gravitoelectric dipole is generated: a test body on one side of the toroid will be attracted – it’ll be drawn through the center. A test body on the other side will be repelled – forced away from the center. So one one side you have an induced positive gravitoelectric pole, and on the other a negative gravitoelectric pole. This is analogous to a changing current in an electromagnetic toroidal inductor, which generates an induced positive electric pole on one side and an negative electric pole on the other side
But the field is conservative, and follows the same Gauss law as electromagnetic fields: the gravitoelectric induction field inside the toroid is balanced exactly by the opposing gravitoelectric field around the outside of the toroid, summing to zero. So it’s not a propulsion device – it can’t move itself. You could launch test masses through the center if you wanted to, and you could levitate a test mass above the device (on one side of the toroid), but it can’t move itself. To do that, you need either a net negative gravitoelectric charge, or a true gravitoelectric field gradient in one favored direction. Then the craft would “fall” toward the positive gravitoelectric pole and away from the negative one. That’s what Alcubierre’s concept entails, though he shapes the field into a polarized bubble around the craft. Personally, I don’t think that’s necessary – without the bubble of warp field distortion you can still propel a craft; it’s sometimes called a “diametric drive,” a simple gravitational field gradient "leaning" in the direction you want to go, with the craft in the middle of the gravitational slope, like a surfer riding a wave. That works fine, unless the gravitational field gradient varies strongly across the length of the craft and creates tidal forces that strain its structural integrity. As long as the field is big enough and smooth enough at the center where the craft is, that’s not a problem.
Please elaborate on this: "gravitomagnetic susceptibility and nonlinear permeability". What are these in layman terms?
Just think of it as the gravitomagnetic analogue to ferromagnetism. A cylindrical electromagnetic coil of wire generates a relatively weak magnetic field, unless you put a bar of iron inside of it – iron has a high and nonlinear magnetic permeability (and therefore susceptibility) – so it greatly amplifies the magnetic field strength of the coil. We just lucked out with iron because it’s a naturally occurring material with this wonderful characteristic of high magnetic permeability – I often wonder what the world would be like if iron, which is all around us, didn’t just happen to have this ideal property for electromagnetic technology.
The same possibility exists with respect to gravitomagnetism, but it’s unclear how to create such a material (though the magnetic moment and the spin of atomic nuclei are coupled, which gives us a starting point). There’s a researcher named Ning Li who was looking into this, but she got funded by the DoD and went dark. Contractors working under the DoD don’t generally publish – military research is almost always classified.
The main thing to keep in a mind is that univers is 13.5 billion years old. There was plenty of time for intelligent life to develop in many places. UFOs are not all made in the same factory. There are civilisations with very different levels of developement. Some UFOs appear verly primiteve, with lots of pipes etc. While other appear to be solid-state tech. This creates a difficulty in a research, because creates lots of variations to deal with.
Eh, sort of. Lots of different styles of craft are reported, but they exhibit strikingly similar performance characteristics across a wide range of designs. The laws of physics are truly universal, and many if not most of these craft seem to be utilizing a similar kind of field propulsion mechanism. I’m sure that some civilizations have better mastery over the physics propelling these devices, but they all appear to be employing some kind of gravitational field propulsion technology unknown to modern mainstream science. Which makes sense, because that’s the only theoretical method that we’ve discovered that would hypothetically permit a traveler to take a jaunt to Alpha Centauri and be back in time for lunch - without incurring any special relativistic time dilation effects.
Now, this is the best thought I ever read on this subject. Thank you for helping me understand subject better.
Glad to help. If anyone wants to crunch the numbers, there’s a nice treatment of the subject here:

I was doing specific research on engine rooms. However abductees can be of questionable reliability, such "swimming pools" and "columns with blue liquid" were described by few other abductees. I know its far fetched, but my current thinking is that these central "swimming pools" are used as a ballast, as something for gravitomagnetic column to grab on and lift the craft. That might be that high gravitomagnetic susceptibility & permeability material you talked about. Otherwise, its inexplicable why would they carry so much of stuff that is neither fuel, nor food across intergalactic space.
If those accounts are accurate, I would assume that’s unrelated to the field generator – you’d probably want a solid material with high gravitomagnetic susceptibility to amplify the field, because the material will respond to the forces acting on it. If you’ve ever seen ferrofluid you’ll understand what I mean – you wouldn’t want to be dealing with some weird fluid deforming and exerting changing strains against a container; it’s better if it’s rigid so it stays put. Here’s a funny little video demonstrating ferrofluid deformations in a magnetic field:
Fendt is the key. We must invite him to this forum.
That’s a great idea. I love how this forum creates an excellent interactive environment for the Paracast.
Here is a list of less known technical papers by people who followed in Paul Hill's steps:
Thank you for all the resources DROBNJAK – it’s great to have some new material to munch on ;
I should also mention an intriguing theoretical possibility that’s going to be tested in the next few years at CERN: it’s possible that antimatter possesses positive inertia but a negative gravitational charge. Surprising though it may seem, we don’t actually know yet if antimatter falls up or down in the Earth’s gravitational field. So researchers are working on a system to create antihydrogen, then cool it down to very slow speeds, and then try to see which direction it falls. At least a couple of teams are working on this, the ALPHA group and the AEgIS Collaboration:
CERN team uses GPUs to discover if antimatter falls up, not down
It’s generally regarded as an unlikely possibility (for reasons that I mostly disagree with), and there’s a tantalizing twist: a brilliant maverick theoretical physicist named Dragan Hajdukovic has figured out that if antimatter possesses a negative gravitational charge, then the gravitational polarization of quantum vacuum fluctuations would produce effects that look just like dark matter and dark energy. In fact it’s the only theory to date which offers a simple explanation of both effects with only one new postulate. So I’m eager to see the experimental results. Here’s an article about Hadjukovic’s theory:
