Nah Hartey, Physics has always been at odds with itself, just like Science is, you are stuck in a physics rut...Science cant even agree with the best way to sort out the Covid-19 problem, physics has avoided that area mostly, but i feel certain that they too have differences of opinion...A classic satirical example occurs in that great TV series, The Big Bang Theory, where two "physicists" disagree over differing opinions on physics

You obviously know how a modulated radio wave works...An Audio section (Sound, longitudinal, not transverse wave), is "impressed" onto the EM Radio Frequency carrier wave...Of course there is electronic jiggery pokery at work, in the transmitter, and the demodulator section of a receiver that receives the radio transmission ,which leads to "hearing" that sound (longitudinal) wave...The physical medium you mentioned deals with how the energy of transverse and longitudinal waves are propagated...Cancel out the magnetic area of an EM wave, and replace it with a true sound frequency..
The same applies to 2 magnets facing the same polarity that cancel out each others magnetic field, leading to an area where no magnetism exists, fill that gap with a sound source, and hey presto we have an electroacoustic wave...I reckon scientists have already developed such scalar waves, that are already operating over long distances right now..
No doubt other scientists and physicists would have said it would be impossible to create such a scalar wave...Just over 125 years ago, scientists and physicist laughed at people such as Tesla and others, for saying pictures of human beings would be shown in peoples homes on a small screen, that was happening miles away at the same time as watching them on the small screen...How we have moved along Hartey
