Welcome to another episode of the Did You Know series with Amish Tripathi!

In this thought-provoking episode, Amish unpacks the legendary Universe 25 experiment —an unsettling story where a mouse paradise turned into a cautionary tale for us all.

Episode highlights:

• Discover the story of John B. Calhoun, the pioneering ethologist behind the Universe 25 experiment.

• Explore the “four phases” of the mouse colony — Strive, Exploit, Stagnation, and Death.

• Reflect on powerful lessons for humanity: urban loneliness, loss of purpose, and rising mental health issues in crowded cities.

Amish reminds us that the greatest lessons sometimes come from the smallest creatures — and calls on us to nurture compassion, meaning, and true community in our lives.
