Space without objects is like one hand clapping.

Direct, everyday experience teaches us that objects can move from place to place without changing their properties. This leads us to the idea of “space” as a kind of receptacle, wherein nature deposits objects. 

Practical applications in surveying, architecture, and navigation led people to measure distances and angles among nearby objects. Through such work, they discovered the regularities on display in Euclidean geometry.

Hans said to Gretel: "What is space?"

Gretel said, “Space is the receptacle that holds objects.

Hans said, “What if there were no objects?”

Gretel said, “Then there would be no space.”

Hans said, “It’s kind of like one hand clapping.”

Gretel laughed and then Hans laughed too.
