Below my conversation with Orac
Ok to help You with more precission understand Relativity I will give You perfect tool STARS

Orac...................300 000 km ...................Marosz

Einstein like describe motion respect to other objects
Orac exist in the universe stars around above rocket
Please show me star but
respect to this star Marosz MUST REGISTER
ENERGY( rocket is moving 30 km/s )
observation point can change fact that Marosz will not register Energy started by Orac ?
WE CAN REVERSE SITUATION

Orac...................300 000 km ...................Marosz
----------------------------------------------------------
Exist Star ? - respect to this star Marosz will never register energy started by Orac ?
Stars are Important ? or C speed and Motion respect to point where body was in Past ?

PHYSICS
"
Galileo postulated his relativity hypothesis: any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments (it is understood that the apparatuses they use for these experiments move with them).
This idea has a very important consequence: velocity is not absolute.
This means that velocity can only be measured in reference to some object(s), and that the result of this measurment changes if we decide to measure the velocity with respect to a diferent refernce point(s). Imagine an observer traveling inside a windowless spaceship moving away from the sun at constant velocity. Galileo asserted that there are no mechanical experiments that can be made inside the rocket that will tell the occupants that the rocket is moving .
The question ``are we moving'' has no meaning unless we specify a reference frame (are we moving with respect to that star'' is meaningful).
This fact, formulated in the 1600's remains very true today and is one of the cornerstones of Einstein's theories of relativity
MAROSZ
Fact That MAROSZ NOT SEE LIGHT STARTED BY ORAC CAN NOT BE CHANGE IF ON ABOVE ROCKET WILL LOOK OTHER OBSERVER FROM ANY STARS AROUND ROCKET !!!!
