I have explained the matter of simultaneousness in detail in Alice Law Version 5. I will explain it here again.

    

      Letís assume that we are watching a news programme on TV and let there be 3 short news chapters of 5 minutes length which are the beginning, the middle and the end.

  
ē In the beginning, there is the speaker in sight (red bar).
ē In the middle, the picture is fully seen (green bar).
ē In the end, the vision moves away (blue bar).

Letís watch the news programme by pushing START button.

The cross lines on the left represent the television station. As you can see, there are three different reference systems that receive the broadcast. The clocks used in the animation show when the signal sets off from the TV station and each clock carries a news topic which consists of three minor sections (the beginning, the middle and the end). By moving the scroll bar, we can see which frame of broadcast in which position can be watched by each reference system.

    

We have previously seen that electromagnetic waves move at c speed relative to the field in which they are. Therefore, each reference system receives the broadcast through the fields which belong to them. For the planes which are in motion relative to the TV station, there will occur (c+v) (c-v) mathematics. Here we can see that two rules regarding Special Relativity can be identified.

    

Rule 1: If the objects which are in motion relative to each other are in the same space position, they will observe different moments of the same event.

 

Letís click on Rule 1 button. Here, although the distances of the three reference systems from the TV station are equal, they observe different visions on TV.

      

Rule 2: If the objects which are in motion relative to each other observe the same moment of the event, that means they have different positions in space.

     

Letís click on Rule 2 button. Here, each of the three reference systems receives the same vision, although they are at different distances from the TV station. 

        

The animation above was composed in a way that the TV broadcast starts at the same moment for the three reference systems. First of all, letís have the broadcast reach the observers by moving the scroll bar slowly. Then, letís take the scroll bar to the end of the broadcast for the plane at the top. We can click on Rule 3 button instead.

   

We see that the broadcast goes on for the other observers, although it has ended for the plane at the top. Here, we can identify another rule.

    

Rule 3: A moving object observes the events as if they were faster than they really are when it is looking forward, while it observes them to be slower than they actually are when it is looking behind.

    

As you can see, there are very different effects that (c+v) (c-v) mathematics can cause. Here, we have seen the effect of (c+v) (c-v) mathematics on simultaneousness concept. For sure, these effects will relatively increase as the speed difference between reference systems is increased.
