But if magnetism is just another manifestation of graviton-elyson interactions, then this would be a dubious idea.

I'm not sure. However, when magnetic fields mingle, can this constitute a friction phenomenon as we know it? Does a magnetic levitated train experience a significant heat flux coming from the magnetic fields themselves? Now, suppose an appreciable heat flux would exist by "rubbing" two magnetic fields, then such friction would contradict the fact that the train doesn't experience any friction! Of course, air friction is present. Do intertwined magnetic fields really generate heat? Perhaps a secundary process to generate the fields generate heat.

Jan, Don't forget magnets can generate electric power and photons that can be x-rays or radio and everything between. The decay into heat of everything makes no sense since heat is a result of energy interacting with matter. Also heat radiates infrared photons.

OK. I'm merely asking whether "rubbing" two magnetic fields in an absolute vacuum induces a heat flux. If it would, then the magnetic fields appears to be comprised of forms that somehow touch an exchange energy. Do we know what constitutes a magnetic field?

It is just remarkable that relativists and non-relativists will eventually come to the same conclusion: there is an eternal substance that is the cradle of all forms. It is a writing on the wall. GR turns out to have problems with certain aspect and they need to introduce dark matter to make it work.

Humans have argued the existance of a substance since the beginning of time. Now that I think about it, it reminds me of some lecturer I had who gave some advice on doing exams: "Suppose you have many ideas, but you are in doubt which one will be the answer to the question, then it is likely your first idea will be correct."

The first idea of humans was an "aether". This is likely to be true. []

Show me something more convincing than ancient classical myth, (i.e., a reproducible experiment), and I'll show you Elysium.
