Aether, Air, Space

Aether, Air, Space
Aether, or air, or space. It is not known whether or not it exists. However it is a continuum and seems critical to the motion, movement, spin, travel, as well as to appearances. It is a medium with relations to travel by airship as well as relation to travel of light. It surrounds the earth. It also has associations with the spiritual dimension. Whether aether matters or not may depend on the mode in which is encountered (by light, by airship).
