AETHER floats above AER and is illuminated with Heavenly light. He’s a very bright lad, and even on the clearest day we only see the merest trace of his splendor as it filters down to us. At night his mother NYX draws the curtains and the gloom of EREBUS descends upon the world. When morning comes, his sister HEMERA wafts away the murky mists and his radiant glow is seen again.
Attempts to discover traces of the aether on Earth were carried out by Michelson and Morley in a famous experiment of 1887. Did they find any? Nope. This non-result led directly to Einstein’s Theory of Relativity, but dashed their hopes of selling bottled aether to the physics community.
