THE SHUTTLE IS APPROACHING THE EARTH
Depending on the performance of the operating system you use, errors may come up in the animation. In this animation, the Source Object and the Image Object must reach the finish line at the same moment in all cases. The Image Object can never reach the finish line before the Source Object. If they are not reaching at the same time, do not watch the animation because it will give you wrong information. I am warning you because it happened to me. It worked out when I restarted my computer.
Please do a time test beforehand. When you play the animation at “1 c” value, if the Travel Time of the Source Object is between 0:98 and 1:05, we can say that the everything is going well. The ideal case is 1:00.
In the animation, how an observer on the earth would perceive the speed of the Image Object when the shuttle is approaching the earth is shown.
If you play the animation by giving it the value 1, the speed of the Image Object reaches infinity; in other words, it becomes undefined. The moment the Source Object arrives at the finish line, the Image Object will appear on the finish line.
In the animation, how long it takes for the Source Object and the Image Object of the shuttle to cover the distance of “1 light speed/second” is shown in comparison. The Radio Buttons on the left set the speed of the Shuttle (Source Object). Please give the animation a value here, click on the Play button and watch the result.
