A new short film by Swedish artist Erik Wernquist uses audio from Carl Sagan's 1994 book "Pale Blue Dot: A Vision of the Human Future in Space" and original animations to visualize what life might be like after Earth.
Wernquist based all of his images on real scientific ideas and concepts from NASA, which you can read more about on his site.
According to the description:
The title WANDERERS refer partly to the original meaning of the word "planet". In ancient greek, the planets visible in the sky were collectively called "aster planetes" which means "wandering star". It also refers to ourselves; for hundreds of thousands of years - the wanderers of the Earth. In time I hope we take that leap off the ground and permanently become wanderers of the sky. Wanderers among the wanderers.
