On July 16, 1945, the United States conducted the world's first nuclear test, but concerns arose about whether it could accidentally ignite the Earth's atmosphere. Scientists, including Edward Teller and Robert Oppenheimer, conducted calculations to assess the risk. They determined that the conditions required for such an ignition were highly unlikely, involving extreme temperatures and enormous amounts of material. The safety factor was significantly higher than previously thought, making the scenario implausible. Despite initial fears, the test proceeded, showcasing the power of scientific analysis in dismissing existential threats.
1. The world's first atomic test, conducted by the United States, took place on July 16, 1945 .
2. The test was overseen by legendary physicist Enrico Fermi .
3. Fermi was quoted as taking bets on whether the atmosphere would be set on fire by the test .
4. The test was part of the Manhattan Project, and many of the world's top scientists were involved .
5. The scientists were considering the possibility of the Earth being destroyed by the first atomic blast .
6. The question of whether the first nuclear blast would accidentally ignite the Earth's atmosphere was taken seriously by the scientists working on the Manhattan Project .
7. The energy from a nuclear bomb expands outwards in more or less a sphere .
8. If this energy causes additional fusion events, the sphere will get bigger and more energetic .
9. The scientists estimated how many nitrogen atoms would be in the air and how likely it would be for them to fuse with nearby nitrogen atoms .
10. The scientists calculated that the safety factor, which is how much safer the losses are than the gains, could get as low as one point six .
11. The scientists concluded that no bomb they considered could feasibly lead to the end of the world .
12. The nuclear bomb that was dropped on Hiroshima Japan in August 1945 released less than a single kilogram of matter underwent fission .
13. The energy released on the city that day was equivalent to just half a gram of matter converting directly into energy .
14. The scientists calculated that it would take roughly a million times more material to ignite the atmosphere .
15. The scientists considered a final protection that would theoretically protect us from atmospheric disintegration .
16. After witnessing the first atomic blast, Robert Oppenheimer gave a famous quote from Hindu scripture, "I am become death, the destroyer of worlds" .
