Well, we need a start.
Releativity is about motion. 

Do you know that the first  remarkable contribution to the concept of motion came from the Greek philosopher Aristoteles. Well, not a bullseye shot, but a fine effort for a time when it was impossible to look at stellar objects other than with the naked eye.  He thinks objects tend to move when a force is exerted on them, and stop when the force is no longer exerted. You might even think it is true. May be a touch of 3d might reveal some of the truth for you. This will be our first video. To show you his point of view and let you put your idea on the matter: Do objects need a continuous force to keep their state of motion? Do you agree with Aristoteles?
