Antigravity by itself would merely affect a decrease in the weight of a mass, relative to the field in which the mass exists. But, if we could effectively control antigravity we could lift any mass and deliver it to any location on the planet as though it were securely packed in cotton wool.
In other words, an apparatus capable of controlling antigravity would allow us to move the most massive object from one place to another without any difficulty whatsoever. Whether across the oceans or over the highest mountains, no geographic location would be excluded from the benefits of controlled antigravity.
In common terms of understanding, antigravity is the opposite of gravity, as antigravity is an inverse process of gravity.
As gravity is a dynamic condition of field, it is not necessary to change the field in which the mass exists in order for antigravity to lift the mass into the air. But what is necessary is a separate unified field system capable of modulating it's own field, in a controlled manner, relative to the field in which it exists.
In other words, there are two relative field systems, in relation to a unified field within a unified field, whereby the second field, which can be modulated in a controlled manner, can provide an antigravitational response relative to the Earth's field while the gravity of the Earth remains unaffected.
So a system capable of antigravity can function within the field of the Earth, where it takes advantage of the Earth's gravity to affect antigravity.
The field of the antigravity devise is not reversed relative to the field of the Earth, such is the case where two opposite magnetic poles attract and two like poles repel. As in the case of an antigravity devise, antigravity is the affect of an increased underlying energy potential associated with the devise relative to the energy potential of the field in which the device exists.
To make this easy to understand, consider a balloon filled with hydrogen gas which rises effortlessly into the sky, as it is the underlying energy potential of the hydrogen which makes this antigravity demonstration possible.
And certainly the hydrogen is lighter than air, but only because it has such a high underlying potential of energy relative to the field in which it exists.
The hydrogen balloon is following the path of least resistance, which happens to be up rather than down. So we would be quite correct to classify the hydrogen balloon as an antigravity device, just as we can classify the Moon as an antigravity device.
The underlying energy potential of the Moon is higher than that of the Earth, and as the underlying dynamic energy (ntffa) of the Moon is continuously accelerating faster than that of the Earth, the Moon continues to slowly move away from the Earth, despite our seemingly flawed perception of there being a gravitational attraction between the Earth and the Moon.
But it would be wrong to think that antigravity involves gravitational repulsion per say, as this would give us a false sense of the condition associated with antigravity.
Antigravity is simply a matter of affecting a differential in dynamic potential, in that a mass having a higher energy potential than that of the field in which it exists will rise, whereas a mass having a lower energy potential than the field in which it exists will fall.
But remember that we are talking about an underlying force of energy in terms of non-linear time field frequency acceleration.
So, we can conclude that antigravity is a process affected by an increase in the underlying energy of a unified field of frequency.
