Aetherspace is a frictionless reality appearing as similar to deep space rather than an atmosphere or ocean, often metamaterial (non-physical) in nature.
Features nonlocal (macroscale nonlocal casuality), and psychotronic phenomena. Includes skies, worlds, and oceans, and populated by a huge variety of native lifeforms, and countless ontocosms, although the higher octaves and resonances are far more difficult to reach. There are various parameters, such as “higher”, less dense, atmosphere-like leptether, and “lower”, denser, water-like baryether. Bioships, Kaijuzoa, and other parabiota fly or swim through or are carried along by and nourished by the aetheric currents and tides, and derive their sustenance from the universal qi or pneuma that is easily accessible here. Zoneships and ftl vessels may be paradoxical in this reality.
As aetherspace is intermediate between paraspace and more transcendent realities such as noetic and psi space, phenomena such as thoughtforms, the aura, mindborn, and paranormals, begin to appear here, and in certain instances can be empirofixed. In contrast to empirospace where things are real even if you don’t believe in them (and not real even if you do). Even more than paraspace, aetherspace cosms tend to be narrative-suffused with high imaginal content, the laws of physics less rigid, and with a greater predominance of proj and consc over cosm. Hence there is more magic, impossible technology, fantasy creatures, monsters, etc.
It also constitutes a sort of cosmic and metacosmic subconscious or unconscious, causal origin of physical phenomena, in which realspace spacetime exists as the “tip of the iceberg” to use the Freudian metaphor.
