Information on the location
In astronomy, the cosmos refers to the entire physical universe as an ordered system instead of its antithesis, chaos; an orderless mess. Pythagoras is credited as the first person to apply the term to the Universe. The location is influenced by Neil deGrasse Tyson's television series Cosmos: A Spacetime Odyssey, which was originally run by American astronomer, Carl Sagan.
