Question

which is the most powerful bomb in the world

Answer 1

Tsar Bomba (Russian: Царь-бо́мба, tr. Tsar'-bómba, IPA: [t͡sarʲ ˈbombə], lit. Tsar Ivan bomb/King of Bombs;) was the Western nickname for the Soviet RDS-220 hydrogen bomb (code name Ivan[3]or Vanya), the most powerful nuclear weapon ever created. Its test on 30 October 1961 remains the most powerful explosive ever detonated. It was also referred to as Kuzma's mother (Russian: Ку́зькина ма́ть, tr. Kúz'kina mát', IPA: [ˈkusʲkʲɪnə ˈmatʲ]),[4] possibly referring to First secretary Nikita Khrushchev's promise to show the United States a Kuzma's mother (an idiom roughly translating to "We'll show you!") at a 1960 session of United Nations General Assembly.[5][6]
