If you took every nuclear weapon ever built at the height of the Cold War, lumped them together, and blew them up at the same time, that would be one one-millionth of the energy released at that moment.
Se pegássemos em todas as armas nucleares construídas no auge da Guerra Fria, as juntássemos todas e as fizéssemos deflagrar ao mesmo tempo, isso seria um milionésimo da energia libertada naquele momento.
