Interesting discovery (see link below), still makes me curious about the relationship of inner sounds and the subtle vibrations that are being detected by scientist.
The first of which was a “constant vibration” that was thought to be caused by pigeon shit on the dish receptor but was later found to be “just there”. I posted that one a long time ago, sorry no link anymore, lost it.
This story is just another piece, perhaps, of the modern scientific discovery of the “music of the spheres”.
