After World War II, during the Cold War in the Soviet Union and the United States, the Soviet Union planned to dig through the earth, but why did it stop digging at 12262 meters? What did they dig up? Look down.
At that time, this move also attracted the attention of the media in various countries, and there are various statements on the Internet that you can search for, but in the end, what is the reason for stopping?
The tools used for excavation were quite expensive, the Soviet economy was not good at that time, and it needed a lot of money to sponsor the experiment, and in the end, it really succeeded and did not bring any benefits.
It is precisely for this reason that the Soviet Union stopped all this plan to dig through the earth. Do you know any other claims? Feel free to comment below.
