Amazing representation of insignificance

Following Amy’s otherworldly post, this video gives an incredible representation of just how insignificant Earth is within the larger picture.  I particularly like how it shows the sphere of our influence (how far our earliest radio transmissions have traveled) as well as the limited extent of our knowledge (how far we can see/have mapped).

I have to admit, I watched it with my mouth open — gob-smacked, if you will.
