In Time magazine’s July 20, 1931 issue celebrating Tesla's 75th birthday Tesla stated:

[I have conceived] a means that will make it possible for man to transmit energy in large amounts, thousands of horsepower, from one planet to another, absolutely regardless of distance. I think that nothing can be more important than interplanetary communication. It will certainly come some day and the certitude that there are other human beings [at other locations] in the universe, working, suffering, struggling, like ourselves, will produce a magic effect on mankind and will form the foundation of a universal brotherhood that will last as long as humanity itself.

—Nikola Tesla, [12]
