Whether or not tachyonic matter coalesces into the superluminal equivalent of stars and planets remains an open question. The math says yes, but so far, observational confirmation has proven elusive. The rim of the galaxy is too far away for even the fastest drones to reach, and our current generation of FTL sensors aren’t sensitive enough to pick out individual gravitational bodies at that distance. No doubt that will change in time and we will eventually be able to learn far more about the nature of superluminal matter.

Another consequence of the well/hill caused by mass-induced spacetime displacement is the effect commonly known as the Markov Limit. Before that can be explained, it will be helpful to conduct a quick review of how FTL travel and communication actually work.

In order to have unlabored transition from subluminal to superluminal space, it is necessary to directly manipulate the underlying spacetime membrane. This is done via a specially conditioned EM field that couples with the membrane (or rather, with the constituent TEQs).

In gauge theory, ordinary EM fields can be described as abelian. That is, the nature of the field differs from whatever generates it. This is true not only of EM radiation but also electron/proton attraction, and also repulsion within atoms and molecules. Nonabelian fields would be those such as the strong and weak nuclear forces. They are structurally more complicated and, as a result, display higher levels of internal symmetry.

The other, more relevant, nonabelian fields are those associated with the surface tension, viscoelasticity, and internal coherence of the spacetime membrane. These arise from the internal motions and interactions of the TEQs, the details of which far exceed the scope of this section.

In any case, it has proven possible to convert ordinary EM radiation from abelian to nonabelian by modulating the polarization of the wave energy emitted from antennas or apertures, or by tuning the frequencies of alternating current to the toroidal geometries through which the currents are driven (this is the method used by a Markov Drive). Doing so results in EM radiation with an underlying field of SU(2) symmetry and nonabelian form, as described in Maxwell’s expanded equations. This couples in an orthogonal direction with the spacetime fields via a shared quantity: the “A vector potential.” (Orthogonal, as tardyons and tachyons exhibit opposite motion directions along their packet lengths, and the conditioned EM field is interacting with both the subluminal and superluminal surfaces of spacetime.) This has often been described as traveling in a straight line along a right angle.

Once the EM field is coupled with the spacetime fabric, it becomes possible to manipulate the density of the medium. By injecting an appropriate amount of energy, spacetime itself can be made increasingly thin and permeable. So much so that at a certain point the energy density of subluminal space causes the affected area to pop into superluminal space, like a high-pressure bubble expanding/rising into an area of lower pressure.

As long as the conditioned EM field is maintained, the encompassed subluminal space can be kept suspended within superluminal space.
