Chemical or Sound Ether

See previous post on Guenther Wachsmuth, who says that the characteristic form of chemical or sound ether is the "half-moon." Indeed, rather like the form of the ear, when you think of it.

The following is a surprising confirmation from astronaut Buzz Aldrin:

On the quality of moon dust: "It exhibited a most unusual quality. I must have kicked about half-a-dozen sprays or more, and each time the dust flew out in front slightly, landing in a perfect semicircle, every grain spraying out uniformly and equidistantly without any rippling effect. I related my observations to Houston, and thought, This is surreal, how each grain of moondust falls into place in these little fans, almost like rose petals."
