  • Op is confusing a tunnel with a hole, a hole is really just an opening in something. A straw has two holes.

    A real Einstein.

    • Or is it?

      At what point does a hole become two holes? When one side is removed? But if a hole was dug into a mountain by breaching the other end make it two holes or did the first one just extend to the outside, making it a hole with two entrances?

      Changing axises: Two holes right next to eachother are two holes. But by breaking down the soil that connects them makes it one hole.
