This Model (ROS Mapped CM Model) shows why the speed of light is a constant without mathematics. This video asks two questions that a layperson may ask then answers them using this animated model. Question 1: How can the speed be constant when all objects can travel at different velocities? Question 2: Why can’t the speed of light be exceeded by adding velocities of two objects traveling in opposite directions? This is the animation of Special Relativity that Albert Einstein never made.
