CHALLENGING VIEWPOINTS

Anyone trying to call the invariant velocity-of-light
dogma into question, is invariably attacked by Einstein's
supporters who will use any method to defend the prevailing
view.

The fact that light is a physical
phenomenon, behaving as it does independently of Einstein's
theories seems to make no difference.

Light travels very fast and that is one of the problems
behind performing measurements with high accuracy, especially
if moving light sources are involved. So Doppler shift
measure are used, whereas in fact distance measurement
would be the most suitable.

Doppler wavelength/frequency shift measurements are indirect
methods and can be rejected as invalid by Einstein's supporters
who say that the product of frequency and wavelength is always
equal to c.

But distance/time measurement would be possible using satel-
lites.

Consider satellites A,B and C moving in the same orbit around
the earth, A and B moving in the same direction with constant
relative distance  and with the same velocity, and C moving
in the opposite direction. C satellite emits radio or light
pulses continuously and A and B catch these signals and register
their arrival time in computer data registers.

The local time registration of each pulse in each satellites is
continuolusly transmitted to Earth and the time difference
of reveived data is calculated.

When C satellite approaches A and B, the time A-B will be:
t1=S/(c+k.v) and when receding t2=S/(c-k.v), where k=0 if
Einstein's invariant light hypothesis is valid and k=1 if the
emission theories (c'=c+v) is valid. S is the relative distance
between A and B.

Calculated time difference will be t1-t2 equal to:
              2  2  2                  2
dt=2.S.k.v/(c  -k .v ) or dt= 2.S.k.v/c  approximately.
                                                            8
Inserting figures- where v= 30,000 km/h or 8333 m/s, c= 3x10
m/s and S= 100 km, k=1 gives approximately 18.5 ns (nanoseconds).
If the distance is increased to 1000 km, the difference is
increased to 1000 km, the difference will be 185 ns, or
nearly 0.2 us (micro-seconds), easy to detect and establish.

As everyone can see, if Einstein's hypothesis were true, the
time difference would by zero.

Who will believe on that ?

By this experiment, the question of the velocity of light and
the velocity of radio wave propagation would be solved once
and for all , relegating this tiresome question and Einstein's
theoires to the lumber room of failed scientific ideas where
it belongs.
