The medium of the "Vacuum" is electromagnetic radiation

From a Quora answer:

[HanDeBruijn]

A decent reference might be Wikipedia's Speed of sound.
The formula that comes most nearby for the speed of a sound wave is

$$ c = \sqrt{\gamma\frac{p}{\rho}} \quad \mbox{equivalently} \quad V = \sqrt{(\gamma P/\rho)} $$

where $\gamma$ is the Heat capacity ratio. Theoretical values are around $\gamma=1.4$ . So I don't understand where a value of $\gamma=2$ comes from in the first place. And of course, when considering values for pressure and density in a vacuum / aether : how are these observed / measured ?

Nice demonstration that the medium of the “Vacuum” is electromagnetic radiation.

Yes, what the pressure term means or where it comes from is not clear. It might just be a model fitting exercise. However the medium of the vacuum is observed to be electromagnetic radiation, so...

off topic but recently saw this paper mentioning that the behaviour of light during speed of sound barrier must violate the mass equivalence relation e=mc2

Han is spot on with his reference. I would only suggest that you take a look at the Prandtl-Glauert transformation (see Wikipedia) which relies on the Prandtl-Glauert factor. Basic laws of electromagnetism have analogous laws in hydrodynamics, e.g., Biot-Savart. See https://archive.org/details/fundamentalsofhy0000tiet/page/206/mode/2up?q=biot&view=theater

Some have concluded that electromagnetism is a gas phenomenon, and that particles are vortex structures.

My comment is off topic, but since you guys are mentioning electromagnetism, I recently discovered magnetic fields can be twisted:

BTW

The radial current in the circuit is on the order of 3×10^9 amperes.[2]

Would it be feasable to extract "unlimited" free energy by plugging a cable to the nearby space electric field?

If supersolid, then superfluid too.
