A new 3D demo that allows you to understand time dilation during space travel.
You choose the duration of the speed of the rocket which will take off from the Earth (and also the acceleration and deceleration durations) and you see in real life the time differences between the reference frame of the rocket and that of the Earth.
At the end we see the total time difference between the 2 frames of reference. The closer the speed of the rocket is to that of light, the more difference there will be between the two measured times.
