It must have been a guy named Hal who as a practical joke installed this monolith in the Utah desert.
https://www.cbsnews.com/news/m...ah-red-rock-country/Most of us have seen the sci-fi movie “2001: A Space Odyessy”. A mysterious monolith appeared four times during the movie to represent a major step in the evolution of mankind. The second monolith appeared at the end of the second sequence in which a lunar archeology site was being uncovered. An antennae then suddenly began broadcasting a radio signal towards Jupiter. The next sequence was about a space ship headed towards Jupiter to investigate why. Hal was the name of the ship’s computer.
What a coincidence that as Juno approaches Jupiter, a monolith was just found by park rangers in the Utah desert.
