Gravity of the kind we are familiar with is only for objects in critical proximity. The unpredictability of precessional motion given mass-interattraction is more conventionally described as the inability of Newtonian mechanics to accommodate all the dynamics of a relativistic universe. Rather, in order to satisfy multiple conservation laws, pulling against gravity will result in changes among several parameters, some of which may leverage others. The generalizations Fuller made about gravitation and its contribution to the bewilderingly complicated precessional effects of bodies in motion on other bodies in motion, had to do with its tendency towards convergence. Gravity brings stuff together, in ways we can easily appreciate in the case of Newtonian effects, and in ways less easily grasped, but nevertheless experienced, in the spiralling galaxies.
Radiation keeps convergence from happening all in one time or place.
Radiation resists the collapse of Universe into a singularity. One might attribute this lack of convergent power to our humanity, our mortality, our tendency to always err. We may identify radiation with the light of awareness in the multi-valent language of synergetics. A prime vector geodesic traces the convergent extreme between self and otherness, but our awareness is always of frequencies, oscillations, erring a little in one sense, then a little in another. This perpetual sense of erring is, again in harmony with many traditions, what synergetics would identify with time, with frequencies, with our experience of being contained and sustained by truths which eternally elude our grasp.
