Nuclear explosion SHOCK WHAT ARE PEOPLE DOING

A nuclear explosion is an uncontrolled process of releasing a large amount of thermal and radiant energy as a result of a chain nuclear fission reaction or a thermonuclear fusion reaction in a very short period of time. By their origin, nuclear explosions are either a product of human activity on Earth and in near-Earth outer space, or natural processes on some types of stars. Artificial nuclear explosions are powerful weapons designed to destroy large ground and protected underground military facilities, concentrations of enemy troops and equipment (mainly tactical nuclear weapons), as well as complete suppression and destruction of the opposing side: the destruction of large and small settlements with civilians, strategic industry, major transport hubs, business centers (strategic nuclear weapons).
