Getting back to Brown's idea of the Structure of Space, I was given his paper back in 2008. The page was titled "Part II" was there ever a "Part I"?
Throughout the paper, Brown discussed the makeup of space. Of course, from the perspective of others, makeup and structure are not necessarily the same but in the paper, Brown was referring to what the Structure of Space was made up of.
He used the term μK and sometimes spelled it muK. He postulated that there were areas of low μK and high μK. Obliquely he referred to those areas where μ could be low and K high along with the reverse being true.
μ (Mu) is the magnetic permeability of free space and K is the dielectric constant. The vacuum of space has a dielectric constant of 1. Our atmosphere at sea level has a dielectric constant slightly greater than 1.
In the book "Defying Gravity", Paul Schatzkin wrote of an event that took place after Brown was discharged from the Navy and he and Josephine were driving across country to California where he went to work for Vega Aircraft. Well they were in a restaurant and has purchased some post cards. It was raining outside and the cards had gotten wet which then caused the cards to ripple much like a sheet of corrugated metal. We were led to believe that this was a Eureka moment for Brown. Perhaps it was and perhaps it was a eureka moment in another direction but I intend to explore this.
So, Brown hypothesized that space was made up areas of μK. These areas were much like the water on the ocean. Areas where there are low currents and toward the shore will find places where the flotsam will lodge. This is an example of an area of μK.
...to be continued but open or discussion if anyone wants.
