The Mightiest Machine is a science fiction novel by American writer John W. Campbell, Jr. The novel was originally serialized in 5 parts in Astounding Stories magazine from December 1934 to April 1935, and was published in book form in 1947 by The Hadley Publishing Co. in an edition of 1,200 copies. Campbell was a leading figure in the Golden Age of Science Fiction.


Plot introduction

The story is the first to feature Campbell's hero Aarn Munro.This space opera novel concerns the harnessing of energy from the sun and encounters with aliens who turn out not to be truly alien at all. It also touches on the legends of ancient civilizations on earth, Mu in this case, and what may have happened to them.


Astounding reviewer P. Schuyler Miller described the 1947 edition as "perhaps the climax of the super-physics school of science fiction which 'Skylark' Smith had started." [1] Everett F. Bleiler identified the novel as the paradigm of "the Campbell hard space opera," noting its "great quantity of fanciful and ingenious scientific extrapolations, fictional weaknesses, and polarized social simplistics that regard genocide with equanimity."

The protagonist also invents and employs devices such as Infrared vision googles and miniature remotely piloted surveillance drones.


The novel contains the first known use of the phrase, " infinity and beyond...," although it is unlikely the reference was picked up from by authors of Toy Story for use by Buzz Lightyear. Chapter V: "Her crew on that trip that was to lead them to infinity and beyond consisted of Aarn Munro,..."
