A Simple Demonstration of Space/Time Relativity

[Deesse23]

Thats not relativity you demonstrated. You demonstrated that angular speed is not equal to linear speed. All dots on your paper have the same angular speed (depending on the rotational speed of your paper), but only dots at the same distance of the center have same linear speed. Dots more distant from the center DO move quicker.

If you want to demonstrate relativity you either need waaaaay bigger speeds or waaaaay bigger distances due to c.
