This coin is a great example for how unique the shape of a coin can be. After all, it was inspired by a special topic: the space-time continuum.
Whoever associates space-time continuum with Einstein is correct, because space-time is related to the theory of relativity. It is a four dimensional structure that joins space and time, and takes into account the speed of the light. Even Aristotle explored the concept of space-time. The general theory of relativity later focused on space and time curvature, in other words, the coordinate axes that are no longer linear. With its unique and special shape, the coin takes up the possibilities of representing the space-time continuum, as found in physics. In addition, it also includes a removable magnetic ball.
