Tachyon vesicles, usually found in interstellar space, in comets, and in the rings of gas giants, are piezogravitational bubbles which, when stimulated by coherent radiation, produce four distinct effects.
Tachyon vesicles, when stimulated by coherent radiation, produce a grav field which is highly directionsal and variable in intensity. By allowing the vesicles free movement, and by varying intensity and wavelength of the radiation, almost any grav effect can be produced.
Generally, since vesicles are fragile, total vesicle mass should be at least 0.00000364 of the mass being moved.
A stimulated tachyon vesicle produces a single ultrawave tone. These tones range through six octaves on the UW Effect Scale. Amplitude modulation carries a signal which can be detected in a receiving set. By the variation introduced into the receiving vesicle, decoding can be accomplished even if the two units are not tuned to the same note -- although best results are obtained from units tuned to whole multiples of an octave apart.
A "sealed-beam" ultrawave circuit obtains between to sub-vesicles propduced from the same parent in the same size. Since each vesicle is extremely sensitive to its twin(s), very low amplitude can carry a signal indetectable even to vesicles tuned to the same note.
The Free Peoples of the Scattered Worlds use a frequency modulation ultrawave signal which is totally indetectable without the tuneable antigrav.
The range of ultrawave signals is generally limited by galactic radius, according to the following:
|Fraction of Galactic Radius||Signal Strength|
|1/8 (1.9 kpsc)||100%|
|1/4 (3.8 kpsc)||98%|
|3/8 (5.6 kpsc)||92%|
|1/2 (7.5 kpsc)||83%|
|5/8 (9.3 kpsc)||67%|
|3/4 (11.3 kpsc)||37%|
Conversion to tachyon (faster-than-light) phase is a catastrophic effect that takes place when a tachyon vesicle is overloaded with energy. In response, the vesicle expends energy by producing a field which converts all particles within into their tachyon equivalents. The triggering energy varies on a logarithmic scale, according to the total mass of the system. Masses above 10^25 kg cannot be converted; the vesicle(s) will destabilize first.
The radius of the conversion field is determined by the total mass of vesicles used, and is given by r = 1.65*(m)^(1/3).
In the presence of too many shifting grav fields, tachyon vesicles will destabilize; the precise destabilization potential (and hence, speed limits) are given by Basse's Law.

A rotating tachyon vesicle, within a grav field produced by a resonating vesicle, creates a primitive version of the K1 defense screen. Variations in energy, rotation, frequency, etc. can modulate the field to just about any desired configuration.
The L-type pressure screen is a sophisticated antigrav effect, rather than a true defense screen.
