The dynamics of cyclical formation can be likened to dust cloud evolution where complex plasmas naturally self-organize themselves into stable interacting helical structures and eventually rotate. Likewise, string polarized energy fluxes self-induce helical waveform patterns where the resulting carrier's phases are set to rotate into a ringed structure by default, given there is no dimensional time factor involved. Another way to look at string formation and carrier collapse can be likened to an oscillating form. Pulsing energy interactions cause elastic forces and potential to form circular distributed patterns seeking symmetry.
String symmetry is key to physical manifestation. It is the process that delivers ring energy payloads in a sequential manner to the physical microcosmic level due to wave motion, elastic conservation, and force equalization.
Just as objects have a center of mass, closed strings seek rotational cycle equilibrium, creating an inward "concavity" force similar to a barycenter. Energy vectors from string oscillations are constantly exerting rotational forces unto its focal point fo which wavers and seeks balance. This focal point induces the formation of a series of secondary inner vortices, like feedback ring layers or pond wakes in reverse, that eventually compounds energy oscillations into a final demodulated state. This the point (fo) of final sequential payload transfer into the physical dimension.
Much as with a bowl of water, when its surface is struck, water wakes race in harmonically-separated waves toward the center where they collide, then return back to the bowl's edge, only to return toward the center, and so forth. This is how strings relegate energy toward the physical dimension. The energy transfered Ec is a conglomorate of all forces F and oscillations w that are elements of what eventually will become wavelength subject to time. While strings have no outer bowl surface to clash against, they exert force in a toroid configuration. The string's balanced perimeter is maintained by the string's carrier frequency created by the conglomeration of energy patterns on the string itself.
The string's focal point is the energy transfer point into the physical plane. Concavity is the wave focusing force that emerges from outside to the inside of the string compacting, demodulating, and sequencing ring energy.
An example is a vibrating round plate with powder shavings on it. Vibration causes powder to separate in harmonic patterns into a symmetrical ringed structure.
Symmetry is therefore a function of string waveform resonance. Once formed, the basic carrier, as explained above, creates inner harmonic waves that oscillate back and forth from its focal point. Thus, becoming a breathing pulsing vortex, alternating stored energy toward the center and along its perimeter. The vortex itself is thus the carrier. That's what isolates and makes string structures their own dimension and repository.
Material symmetry is indicative of embedded string symmetry functions, indicating that string structures are symmetrical, and string repositories above them are also symmetrical vortices.
