Theoretically, the equivalent of the largest hydrogen bomb explosion can be infinite (as long as the technology is excellent and the materials are sufficient).

1. 1954, the United States exploded a 25-million-ton hydrogen bomb on Bikini Island in Basor.

2. Theoretically, after the super hydrogen bomb explodes in Xindi Island, the killing radius is about 1000 km. A problem that the developer didn't consider in advance is in front of us: there is no place to test and explode! Later, after repeated argumentation, it was decided to adopt a compromise: the charge was halved, that is, 50 million tons equivalent. ?

3. Historically (during the Cold War), Khrushchev's team produced the most powerful hydrogen bomb to date-65438+1100 million tons of TNT equivalent hydrogen bomb. The name of this bomb is as terrible as its power-it is called "Khrushchev bomb". According to this theory, the explosion center completely destroyed the super firecrackers with a radius of several hundred kilometers, a killing radius of 1000 kilometers and a comprehensive damage effect radius of more than 4,000 kilometers.
