Neil DeGrass Tyson explained it for the layman.

Hitler's Olympics radio broadcast in 1936.

Now, assume you are sitting in a big comfy den. A nice big Texas house den. That represents the Milky Way.

In the center of the den is the Earth and radio broadcasts were blasted in 1936.

The earth would be but a micro dot and the distance the radio broadcasts traveled would be the size of a golf ball.
