Atomic bomb Quote by Annie Jacobsen
““Castle Bravo had been built according to the “Teller-Ulam” scheme—named for its co-designers, Edward Teller and Stanislaw Ulam—which meant, unlike with the far less powerful atomic bomb, this hydrogen bomb had been designed to hold itself together for an extra hundred-millionth of a second, thereby allowing its hydrogen isotopes to fuse and create a chain reaction of nuclear energy, called fusion, producing a potentially infinite amount of power, or yield. “What this meant,” Freedman explains, was that there was “a one-in-one-million chance that, given how much hydrogen [is] in the earth’s atmosphere, when Castle Bravo exploded, it could catch the earth’s atmosphere on fire. Some scientists were extremely nervous. Some made bets about the end of the world.””

Source Book: The Pentagon's Secret Nuclear Weapons, Annie Jacobsen, 2022
Castle Bravo’s design allowed a brief, intense fusion reaction, raising fears of a catastrophic atmospheric fire and global annihilation.
In simple terms: The bomb could have ignited the atmosphere, causing massive disaster.

A Different Perspective
The probability of atmospheric ignition was later shown to be negligible, but fear persisted.
![“There is a further advantage [to hydrogen bombs]: the supply of uranium in the planet is very limited, and it might be feared that it would be used up before the human race was exterminated, but now that the practically unlimited supply of hydrogen can be utilized, there is considerable reason to…” quote by Bertrand Russell](https://sms4smile.com/quotes/img-quotes/8ed/bertrand-russell-69_advantage_there-is-a-further-advantage-to-hydrogen_959896.jpg)
