The Day the World Almost Ended: The True Story of the Trinity Blast

TLDRIn July 1945, scientists detonated the first nuclear bomb, known as the Trinity blast. There were concerns about the bomb igniting the atmosphere and ending all life on Earth. However, calculations showed that the chances of this happening were near zero. The blast marked the beginning of the nuclear age.

💥The Trinity blast marked the beginning of the nuclear age.

🌍Calculations showed that a nuclear explosion capable of igniting the atmosphere was impossible.

🔬The Manhattan Project scientists considered various factors, such as fusion reactions and energy losses, in their calculations.

Q&A

Was there a real risk of the Trinity blast igniting the atmosphere?

No, calculations showed that the chances of the blast causing atmospheric ignition were near zero.

What were the key factors considered in the calculations?

The scientists considered fusion reactions, energy gains and losses, and the possibility of radiation interaction within a large volume of bomb-heated air.

Did the Trinity blast have any long-term effects?

The blast marked the beginning of the nuclear age and had a significant impact on the development of nuclear weapons.

What was the safety factor calculated for the Trinity blast?

The safety factor was calculated to be 1.6, indicating a low risk of atmospheric ignition.

How much energy would be required to ignite the atmosphere?

It would require an amount of energy equivalent to 20 times more than the current world supply of nuclear weapons, making it impossible.
