suggests anything from 0.06 to 1000 atoms per cubic centimeter,
or 6 * 10^4 to 1 * 10^9 atoms per cubic meter. The nominal
value appears to be 1 atom per cm^3, or 1 * 10^6 atoms per m^3.
For comparison, the density of liquid water can be expressed as
3.35 * 10^28 atoms per cubic meter, and sea-level air is about
2.5 * 10^23 atoms per cubic meter.

I'm not sure if it was that, Cherenkov, or simply that their eyes were
being used as "light chambers" for the muons, protons,
electrons, and whatnotons. I'd have to research the issue,
but no superluminality is required -- except in the sense that the
particles travel faster in light *in a transparent medium*
(as opposed to in vacuo).

Just remember, SR is a luminferous aether theory, whereas BaT is not,
in Henri's view. (Personally, I'm not sure I care if there's an
aether or not, as long as the math works. :-) )
