##### How does the movement of the earth affect lasers?

Laser has got fregrency 120 000 000 Hz

LASER  -.-.-.-.-.-.-.-.-.-.-.

Laser is sending light pack by pack 120 MHz
distaance between exist not exist signal "-.-" = 1/120000000 [sec]

to above we must add very old Law

Inverse Square Law ( Ancient Greece )

Each flat line "-.-" has got 3D shape

More far  from place where signal started = lower intensity of signal

( "lower brightness" )

R = X , 2R = X/4 , 3R = X/9

the same energy portion   but different  area

LIGO PIPE 2,5 Miles LONG , Vacuum
-------------------------------------------
Laser <..<..<..<..<..<..<..<..<..<..<..<..DETECTOR
-------------------------------------------

Problem That we Have to Evaluate if we
use laser in Pipe full of vacuum

Earth Motion Around SUN

Pipe 2.5 miles long light's pack inide ( 1/120 000 000 sec)

--------------------------------------------------------

....<......<.<

--------------------------------------------------------

...............^

............. 30km/s =30 000 000 mm/s

Pipe long = 2.5 miles = 4 km
C speed - Light need 4/300 000 sec for pipe distace
30 000 000 mm/s and time 4/300 000 sec ???

Inside Pipe we have vacuum . Pipe and Earth Are moving in Universe  Pipe motion can not change light's motion inside pipe. We can not push light by vacuum !
Light started short time before above situation is going to detector by strait line ( not Exist C + V earth exist only C )

Detector at the end of the pipe will register light
with small different position respect to place where laser
was set and calibrate . Absolute Earth motion is important for fact where detector will register the signal !!!
