The Æther is discribed as a ubiquitous medium pervading all of space. If one were to remove all the materials and energies depending from the æther the essential ætheric medium would remain. Thomas Edison said it best when he described the ætheric medium as the canvas upon which existance has been painted.
It is this ætheric medium which becomes more tangible through use of a phenolic field. This ætherial effect allows interplanetary travel and communication.
