Energy moves forward. If you throw an object, it continues to move in the direction that you threw it. This is the same thing that happens to energy particles.

Light comes from the sun and moves to the earth.  Sound comes out of your mouth and moves forward.  Electricity moves from a plug in the wall to a light bulb.
