No Art, the impedance of free space is 377 ohms. *Air changes it a bit,
just not enough that we care.

Yes, you are correct and I misspoke!
The point I was trying to make that space as we know it, yes free
space, has a resistance value tha same as the carpet and balloons that
I described earlier. This resistance gives substance that the
atmosphere is a true substance or a dielectric and not just nothing or
an empty space. After all, if it was a true nothing or vacuum then
outside forces upon the boundary with in which it exists would
compress that boundary until it really did not exist.
This same explanation explains why a plane or a satellite can transmit
and receive a radio signal because in each case it qualifies as a
Farady cage. As to whether we care or not is dependent on whether we
need the outer layers around earth that sectionalize the boundary
around earth because it is our boundary that hold the layers in
position to provide frictional qualities against the communication
particles. The bottom line is that the eather is not just nothing but
a sea of particles separated by charge and can just as easily land on
a sattellite or impinge on the high density magnetic field at our
magnetic poles where light is created. I would also point out that the
speed of light is determined by "white light" which thus limits the
visible spectrum of light seen at the poles.
Bottom line is that our outer space is not just nothing but is a
dielectric substance that has
a measurable resistance which puts us back fully into the camp of
Newton from which we strayed 100 years ago. The mathematical error is
real and just like a check book that doesn't balance time competes
against its correction.Remember that all this is a result of illness
which forced me back in years where my vocablery was that of a child
and consisted of what, why, when, e.tc that reflects human curiousity
and where one is forced to start from the same datum line which is one
of first principles and not blind acceptance as our experiences and
education system rewards.
