The aether does not exist. Why? Because https://en.wikipedia.org/wiki/Michelson%E2%80%93Morley_experiment
The word aether is used to refer to many things. I simply use it as it is a recognized FE term, though my definition varies.
Still waiting for a response though I can tell you that.
Consistently ignoring my replies and refusing to say what is wrong with any of them, expecting me to somehow guess, is not 'waiting for a response.' You've had a response. Until you can actually say what's wrong with it, it stands.
It really does not matter if aether exists or not, its a word and the word exists.
What matters is that the thing you are describing with certain properties.
The question is, do those properties exist within your framework? If not your then your framework needs to be reviewed.
And this is the most important message of this thread. Aether, as a basic concept, certainly does exist. It is
defined to be something that is proven to exist. This isn't an assumption, or anything special, this is a simple definition: a change of word. That's all. If a dog exists, a canine exists.
What matters is the property I assign to it. That's all: can we say that aether possesses the high-to-low property? And as I explained in my first message, the answer is yes; the law is universal. Beyond outside interference, all things do.
Ultimately however, this only shows that the definition is reasonable. Observations are required to firmly tie it to reality, and these are met by any experiments of observations you care to make. This'll be covered in message 4.
