Okay, with this tool (these animations) we should be able to clear everything up.
What I did is take this train concept:
The train-and-platform experiment from the reference frame of an observer onboard the train
Reference frame of an observer standing on the platform (length contraction not depicted)
Then I made an animation and blew things up in scale. I did this so that each ship could look as though they are hardly moving relative to each other. They are separated by such a large distance that they appear slow ( in the minds eye ). And also, so that on the illustration, they could remain in position. As you can see the blue lines represent the path of the light in order to reach the other ship and how it increases with time.
Two ships that are One light second in length. Moving in space relative to each other and we say:
-Neither ship underwent acceleration, they were found in space
-A person is located in the center of each ship.
-Each person begins the experiment by turning on light a light switch located at the center of the ship.
-This light switch sends a light signal to each end of the ship.
-On its path it passes through a series of evenly spaced devices that turn on a very bright light located at each device.
-Each blue circle represents the blue lights.
-The perspective is (birds eye view) however, it represents the data and/or results that the person in ship A records. (it should be the same results for each ship).
Experiment and Animation #1:
This animation shows the lights turning on towards the front and rear of the ship in a synchronized fashion (relative to person A inside ship A) after the person turns on the switch at t=0http://hypography.co...=1&d=1230358517
Experiment and Animation #2:
This animation shows the lights turning on towards the front and rear of the ship NOT in a synchronized fashion (relative to ship A observing ship
after the person turns on the switch at t=0http://hypography.co...=1&d=1230358517
The light moves exactly 3 faster one way than the other. Ignoring some of my distances let's explain and calculate.
If I am correct:
relative velocity = 1/3 of C
distance between A and B = (later determined)
(.25 light seconds = 75,000,000meters)
