its hard to really pinpoint any one reliable source of information. it contradicts aspects pf physics and quantum physics and leans more toward the concepts within electro magnetism, frequencies and fields. all areas which aren't seriously explored by mainstream science

theres also a spiritual or religious aspect to it. weirdly enough the most info i tend to find is where its talked about in passing, or mentioned

from my own understanding which is still in its infancy, is that the Aether is our magnetic field and so much more, its also the medium in which frequencies and smaller magnetic fields can interact. energy can be transferred to and from it. iv read some say that its the "spiritual realm" or an energy that certain people can tap into.
