If men could move out of infancy at half a mile an hour and get up to eighteen thousand miles an hour in one lifetime, well, who was to assume that the walls of the universe were safe from future men?
In "Of a Fire on the Moon," Norman Mailer explores the rapid advancement of humanity, emphasizing the potential for future progress. He suggests that if men can evolve from moving slowly to achieving extraordinary speeds within a single lifetime, one cannot dismiss the possibility that they will continue to push boundaries. This notion raises questions about the limitations of the universe as humans strive for greater achievements.
Mailer contemplates the idea that the universe's constraints may not be as impenetrable as once thought. The progression from infancy to advanced capabilities reflects the human spirit's resilience and ambition. As mankind advances technologically and intellectually, the walls of the universe may very well be challenged, suggesting an exciting future filled with endless possibilities.
