"To the Moon"
Why do we love one another only “to the moon and back”?
The distance between the moon and the earth is 384,400 km = 1.2 light seconds. The farthest known galaxy in the universe, discovered by the Hubble space telescope in May 2015, is 13.1 billion light years away.
The origins of the phrase are unclear, but it’s time to stop this short-distanced love. Below is a concept design for multi-purpose greeting cards, made for those times when you're love travels just a little farther than the moon.
