In the late 1950s, a scientist named John B. Calhoun intended to create a paradise.
Not for humans—but for mice.
He named this experiment Universe 25. A world where hunger, thirst, and danger did not exist. Food was unlimited, water was clean, and shelter was completely safe. For the first time in nature's history, life was freed from all hardships.
The mice thrived, grew rapidly, played, slept, and lived fearlessly. Their small world was filled with movement and life—a bustling city of peace and comfort.
But as weeks turned into months, the population began to grow… and somewhere within the paradise, something started to break down.
When the number reached nearly 600, an invisible rot began to spread.
Powerful mice seized the best spots.
The weak became isolated.
Mothers, who once risked their lives for their children, began to abandon them—even attacking them.
Males either became excessively aggressive or strangely indifferent—refusing to breed.
Harmony completely shattered.
Then came another phase—silence.
No new births, no fights.
Only loneliness.
Mice sat in one place, grooming themselves repeatedly, as if waiting for time to pass.
Food and water were still present, but the desire to live had vanished.
