Earth: *creates a graviton without spending any energy*
Graviton: Why have you made me?
Earth: You are to travel into space, find something, then bring it back to me.
Graviton: But why will they listen to me?
Earth: You are a graviton, the ruler of the universe. They MUST listen to you!
Graviton: But what if I encounter troubles on my path?
Earth: You cannot, nothing can stop you. Nothing can alter you. Nothing can deter you, now go!
Graviton: *accelerates to an infinite speed, and half way to full speed, arives at something*
Moon: Well, hello there!
Graviton: Hello! You are to come with me.
Moon: But where are we headed?
Graviton: Back the way I came.
Moon: But you are a massless particle. How can we know where you came from?
Graviton: This is not important, just come.
Moon: I cannot move myself, I need energy to change my velocity.
Graviton: Use mine!
Moon: But you have none. You are massless, stateless and energyless. Whomever made you did so without spending energy, thus you have none.
Graviton: But I am ruler of the universe, you must do as I say!
Moon: But you're massless...
Graviton: so?
Moon: Well that means you don't exist.
Graviton: *poof*
