The second half of the twentieth century shook the world at the consequences of a nuclear war between the Soviet Union and NATO. And with good reason: we know from the effects of Hiroshima and Chernobyl that nuclear explosions can cause death and destruction in a wide area. It is true that relations between the United States and the successor to the Soviet Union, Russia, are noticeably friendlier than in the days of the Cold War, but still. What would happen to Earth if a nuclear war still broke out? This video, set many decades after a devastating nuclear war, deals with it in a playful but scientifically substantiated way. At least until the corniness hits after the tenth minute.
In this clip a less scientifically responsible compilation of images from films in which scenes from a nuclear war occur.
The clip goes wrong by stating that the Earth's axis can shift due to nuclear explosions. In fact, even the largest nuclear explosions that can be generated by man are too weak for that.
Could there be another nuclear winter?
