In 1968, scientist John B. Calhoun created Universe 25, a sealed habitat with unlimited food, no predators, and perfect conditions for mice. Despite these ideal circumstances, the population initially exploded into thousands before collapsing due to social breakdown: mice became violent without cause, mothers abandoned their young, births stopped, and the final survivors (called 'the beautiful ones') ate, groomed, and slept but never fought or bred. Calhoun concluded that when survival is guaranteed and life loses its challenges, purpose, and meaningful roles, societies can collapse even without resource scarcity. This experiment demonstrates that purpose and struggle are essential for maintaining social structure and life's meaning.
