"What Special and General Relativity Tell Us About the Nature of Our
Universe"
The basic tenet of both Special and General Relativity is that the
laws
and constants of the Science of Physics are the same within all velocity
and/or elevation reference frames. When correctly interpreted, it means
that, when these laws and/or constants are measured WITHIN a given
velocity
and/or elevation reference frame, they have the same NUMERICAL value as
when
a corresponding measurement is made WITHIN another velocity and/or
elevation
reference frame. It does not imply that, when they have the same ABSOLUTE
value in all reference frames, it means that a change in reference frame
produces a change in the ABSOLUTE SIZE of the measuring device(s) used to
make the observation. This change(s) serve to conceal any changes in the
ABSOLUTE VALUE, That is what relativity theory is all about! Once that
fact
is understood, with a little bit of insight, relativistic effects become
intuitively obvious. (For easily understood illustration of this type of
effect, consider a hypothetical measurement of the price of gasoline in
Windsor, Ontario Canada and ten miles away in Detroit Michigan USA.
Consider
next that gasoline was found to be $3.00/gallon at both locations.
Gasoline
would then be invariant between the two locations in the same sense that
physical laws an constants are invariant between elevations or velocity
reference frames. However, in Canada gasoline is measured in terms of the
Imperial gallon and in the USA gasoline is with the US gallon which is 20%
smaller.. As a result, in the same terms as defined by physicists for
their
measurements, is a "constant" within the reference frames of Windsor and
Detroit, but it is not CONSTANT in the terms that we use for rational
thought.
The premise of Relativity Theory that the velocity of light is the
same
in all reference frames is backwards.
Your analogy is correct. The speed of light is a constant math ratio as
measured by all observers as follows:
Light path length of a ruler (299,792,458m long)/the absolute time content
for a clock second co-moving with the ruler.
