On August 6, 1945, the U.S. dropped a uranium bomb - Little Boy - on Hiroshima at 8:15 AM, instantly killing 70,000 to 140,000 people, with thousands more succumbing to radiation later. Three days later, Fat Man struck Nagasaki. These remained the only wartime nuclear bombings to date. 

 Lesser-Known Facts from Ground Zero:

1. Precise timing matters: Enola Gay’s bomb detonated at 8:15 AM, damaging terrain and lives within a five‑square‑mile radius.

2. Extreme heat: The Hiroshima blast reached roughly 4,000 °C, vaporizing buildings and igniting a devastating firestorm. 

3. Evolving death toll: Although initial counts estimated tens of thousands, by end-1945 Hiroshima’s death toll swelled—bringing combined fatalities to over 200,000.

4. Survivor voices rise: Fewer than 100,000 hibakusha remain today. Many now speak out passionately against nuclear proliferation, warning that history must not repeat.

 Why It Still Matters:

These untold details remind us that Hiroshima and Nagasaki weren’t just moments in time—they became catalysts for a global peace movement. Survivor testimonies, memorials like the Peace Park, and disarmament activism emphasize the urgent reality: nuclear weapons pose existential risks that linger to this day.
