Example of complicated and total relativity:
I'm flying with a spaceship. Its velocity can increase quickly on travel
speed. It amounts then 99.9999999999% of vacuum light velocity.
At first I set this term into the root of Einstein's term:
g = 1/Ö (1v²/c²) =
707107.
The gamma factor is about 700000. What does is mean all together?
I have to fly a round of a little less than 700000 light years. Finishing
this way I return back to the earth.
On earth are gone 700000 years. The light had overcome 700000 years in this
time and that way for that time: 700000 light years or 6·10^{21}
meters.
On board the time of one year was gone for me: so 700000 years divided by the
gamma factor.
And now here is the list of relativities:
I calculate: During the one year I have overcome about 700000 light years
of my way. Therefore I have flown with about 700000 times light velocity.
The earth men calculate: He is flown next to 700000 light years in 700000
years. So he was near the light velocity in vacuum.
God calculates: He was missing 700000 years on earth. So he had taken a
complete time step of 700000 years for one single year. Just like this, he
has taken the way step of 700000 light years for this one single way step of
one year. The way was also shortened. Therefore he has flown next to vacuum
light velocity.
The little devil on board calculates for me: You are just one year on
travel. It seems for you, hardly time and way are gone. The light would have
overcome just one light year in one year. Therefore you are only flown next
to light speed, namely one board year divided by one board way of one year.
Referred to travel speed, they are 3:1 against me. Am I flown with 700000
times light speed or am I not?
Certainly, I'm not flying with this speed. In vacuum one cannot be faster
than the allowed light velocity in passing of vacuum quanta. If the vacuum would
be really nothing then this would be naturally possible. The real vacuum
consists of compensated matter (remark: we, on earth, don't seem to know the
real vacuum light velocity, because we have measured this speed in the area of
proton neutrino clouds. Each particle thins the vacuum and leads to decrease of
light speed.)
Therefore only the relationship of the observer positions against each
other gives the result of the apparent warp speed. If one only remains at
the position of one observer, never light velocity will be exceeded. However to
all weariness, it is mathematically possible to expect warp speed as
relationship. But even modern experiments could not disprove Einstein's theory
at a difference of group and phase velocity. Causality, too, doesn't be shifted
at experiments of Lijun J. Wang and colleagues of NEC Research Institute,
Princeton, New Jersey (Bild der Wissenschaft, 10/2000, p 13, Licht schneller als
Licht).
