Is the world a cube?
We will never know for sure but I have a very strange explanation. If you imagine the world as a cube that rotates 90 degrees every time the sun rises or sets. Now imagine the bike facing the pole and the world turning 90 degrees.
You might think that the bike wouldn’t move but bikes have wheels. Someone might have tied the bike to the pole to see what would happen when the sun rises.
Do you think this is how the bike got stuck on the pole?
It might just be.
