How big is a nuke?

Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ).

Will there be a nuclear war in the future?

Likelihood of nuclear war As of 2021, humanity has about 13,410 nuclear weapons, thousands of which are on hair-trigger alert. Scientists have argued that even a small-scale nuclear war between two countries could have devastating global consequences and such local conflicts are more likely than full-scale nuclear war.
