Understandably so, I was too when I first started diving into the idea a few years ago.

MMX proved the aether exists, and all the inventions like the AC motor were developed using theory that stems from the existence of aether. It wasn't just Tesla; Faraday, Heaviside, Steinmetz, Maxwell, Dollard, and many more all knew it to be true.

"The Aether has never been detected in any way shape or form; it’s not observable or measurable or detectable, like it doesn’t exist."

That's pretty much how dark matter is described, and it is where I believe relativity dies. It cannot progress in any meaningful way without the aether.

The medium is why light exists at all, since it is the a disturbance of the medium itself. Light stops illuminating once it is no longer propagating through the medium. That is what makes frequency and vibration key, because they are the means of manipulating the aether in order to manifest energy.

You will have loosen the grip on some of your existing beliefs in order to entertain this theory from this perspective.

This was one of the first books that got me into the topic:
