Are you saying that gravity is just centripetal force and nothing more?

No, not in the slightest.
The point is that changing gravity is a very profound thing in modern physics, which is very different from creating a force and movement which has
to obey conservation of momentum and inertia.
If you want to go to the stars, you have to not get squished---inertia does that to you. If you can "warp spacetime" with warp drive, then you need
only a modest rocket, but it happens to get you further.
You step on the gas pedal in your car and you go zero to 60 in 8 seconds say. But suppose that before you did that, you could shrink the space in
front of you so that what before was a meter was only 10 cm relative to your tires. You'd end up going much faster (as in covering ground
difference), but you wouldn't have had to expend any more fuel or have any greater acceleration from your own point of view.
I agree with the general theory in this thread that UFO propulsion has to do with some kind of gravitomagnetic technology. It is clear from the
description of UFO that they are manipulating gravity, else they would be crushed by their sudden and abrupt turns at supersonic speeds.
Yes precisely. Notice also that if they are manipulating gravitation then there must be optical effects as well. Essentially what would look like
plain air or vacuum would act as if it was made out of a thick and wavy lens and refract light in odd ways. This is because in modern gravitation,
absolutely *everything* in physics is affected by it (the genius insight of Einstein, and why gravity is different from all other physical forces).
Gravitational lensing has been seen in observations of very far off galaxies. The amount of mass necessary to create it is equal to that of another
galaxy---according to general relativity as we know it.
Also, this means that if you are observing a craft which can modify gravitational fields, then where it "appears to be" in your regular experience
may not be where it actually is, because of the warping of sight lines that we have no human experience with. It's possible that 'winking out'
and 'winking back in', is not really what's happening---the thing just plain flew from X to Y, but in the process of doing so the gravitational
fields which were created resulted in the optical sightline not intersecting you and then intersecting you again. Also there would be redshift
effects too, changing of colors potentially.
The whole point though is that we humans have no conceivable idea how to do this---we would have to discover some kind of source term in gravitation
which is trillion trillion trillion times stronger than the one we know.
And if such a power or coupling did exist in the laws of physics which is so big, how come we haven't seen any evidence for it yet in our mainstream
scientific experiments? If it's that strong, why hasn't it smacked us in the face? That's my problem with all of this as a scientist.
