| Today I ran into this problem again. What is the difference between sound and radio? A traditional explanation with Relativity says: Sound is compression waves through a medium, and radio is electromagnetic waves through no medium, and light is photon waves through no medium but gravity due to mass attraction changes the paths of the massless photon particles transiting through spacetime in a vacuum at c the max speed of light and photonic causation. (But is there spooky action at a distance faster than c that's more than chance correlation?) Superfluid Quantum Gravity (SQG) and Superfluid Vacuum Theory (SVT) say that the vacuum of space is not nothing; at Bose-Einstein Condensate (BEC) phases of matter, there is a new description of the particles in space. And there should be, because really what is between atoms and electrons in the nothingness of the vacuum of space at what altitude and temperature? And so to describe the path of massive photons and standard massless photons through the superfluid of space, additional or alternate or sufficient superset mechanics to describe dilatant fluid model of spacetime at macro and micro and particle scales. Is it Proca fields for massive photons with Airy-beam-like curvature? /?hnlog Ctrl-F dilatant; dilatant quantum fluid model of gravity : - > How to test whether MHD or SQR [or SQG or SVT] best explain the given phenomena? - "Persistent shock wave around dead star puzzles astronomers" https://news.ycombinator.com/item?id=46679704 - "A universal speed limit for spreading of coherence" https://news.ycombinator.com/item?id=45928486 : > "Physical vacuum as a dilatant fluid yields exact solutions to Pioneer anomaly and Mercury’s perihelion precession" (2019) https://cdnsciencepub.com/doi/10.1139/cjp-2018-0744 .. https://news.ycombinator.com/item?id=45220585 |
Radio waves are light waves.
