Star Trek: The Motion Picture was a movie produced in 1979 that was based on the idea that an artificial life form comes to earth looking for carbon-based units. With all the carbon, hydrogen and other substances in the universe, could it be possible? Is life without carbon really possible?
Such ideas aren't new and have intrigued speculative scientists and artists alike. In the trailer for the 1957 film The Monolith Monsters, movie-goers imagined the results of relentless silicon life-forms ravaging our planet in a horrific, systematic fashion.
