" 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."

You are conflating inertial FoR with relativity. In a Newtonian world (which the real world approximates very well at low speeds), inertial frames of reference work really well, even if machines like gyroscopes still confuse people. Relativity changes all that when speeds get close to c.
I have one question
EM preasure

HOW BIG FORCE IS REGISTERING ROCKET ?

THIS FORCE is RELATIVE ? RESPECT TO WHAT ? :)
PLEASE EVALUATE 45 degree situation ? HOW FAST IS ROCKET ?
p1..p2..p3..p4....me >>> motion
I was in point p1..p2...p3...p4
I'm in point p5
I will be in point p5
HOW BIG FORCE IS REGISTERING FAR FAR STAR
p1..............................................................p2..........................................................p3.................STAR >>>>

ROCKET
DO YO SEE RELATION ? HOW BIG FORCE IS REGISTERING STAR
HOW BIG FORCE IS REGISTERING ROCKET ?
DO YOU SEE NONSENSE ( ROCKET IS MOVING RESPECT TO START or RESPECT TO OWN OLD POSITION )

OK FORCE and PREASURE
HOW big TorQUE WE WILL MEASURE ?

WERE SIGNAL STARTED ? WHERE FORCE WILL HIT ROCKET ?
WHY WE NOT SEE Pi = 3,14.. in famous reduction
