The Kola superdeep well is located in the zone of the Arctic Circle in the most north-western point of Russia and is the deepest underground passage dug in the earth's thickness.
Soviet scientists initiated the drilling of the well back in 1970 and by 1989 reached the level of 12,262 meters.
They wanted to completely drill the earth's crust and reach the upper layer of the mantle, but they had no idea what could have threatened it. Nevertheless, fears about the formation of large-scale earthquakes or the appearance of demons from the Underworld proved to be groundless.
And the work on the project was curtailed due to the fact that at the extreme point of the passage the temperature was so high that the molten rocks dripped back into the well, not allowing scientists to increase the depth of drilling.
Trinity's test was part of the US program "The Manhattan Project" for the development of nuclear weapons. This test, which took place on July 16, 1945, was the world's first explosion of an atomic device.
The initial development of the weapons of the new era was delayed because of fears of the scientist Edward Teller, who took part in the project. He assumed that detonation of a plutonium charge of such power could lead to the initiation of a self-sustaining chemical reaction involving nitrogen, which theoretically could lead to uncontrolled ignition of the Earth's atmosphere.
However, further calculations showed that the possibility of implementing such a scenario is extremely small, so the work continued. The explosive power, produced as a result of the first nuclear test, is estimated at 21 kilotons in TNT equivalent.
The explosion of this device reminded the project leader Robert Oppenheimer a line from the Hindu holy manuscript: "Now I am like Death, the destroyer of the worlds."
When scientists on September 10, 2008 officially announced the creation of the Large Hadron Collider project, some began to believe that this device would lead to the destruction of the entire world.
A $ 6 billion particle accelerator project was created to disperse proton beams over a 27-kilometer tunnel tunnel with subsequent collision, which leads to the formation of microscopic black holes that are believed to have appeared immediately after the Big Bang.
Some believed that the resulting black holes would grow uncontrollably until they absorbed the Earth. However, scientists reject these rumors, since it has already been calculated that each black hole has a limit after which it evaporates. This phenomenon is known as Hawking Radiation.
Magnetosphere of the Earth is an important protective layer, in which are charged particles, protecting the earth's atmosphere from the harmful effects of the solar wind. And what if the big nuclear bomb explodes in this magnetosphere?
The United States decided to find out in 1962. Well, among other things, the purpose of the experiment was to find a possible way to intercept Soviet nuclear missiles in space orbit.
Therefore, the explosion of a thermonuclear warhead was initiated at an altitude of 400 kilometers above the Johnston atoll in the Pacific Ocean.
An explosion of 1.4 megatons was visible from a distance of 1,450 kilometers in the Hawaiian Islands, where an electromagnetic impulse damaged the lighting lines and telephone communications.
Also, in the lower earth's orbit, an artificial radiation belt formed, which lasted for five years and damaged more than a third of all satellites that were at that time.
This project to search for contacts with the "Extraterrestrial Intelligence" includes a set of activities to detect and attempt to communicate with representatives of extraterrestrial civilization.
As early as 1896, Nikola Tesla suggested that radio communication could be used to establish contact with aliens. In 1899, as it seemed to him, he even received signals from Mars. In 1924, the government of the United States proclaimed the "National Radio Day" in the period from 21 to 23 August 1924, when scientists could scan the air in search of radio frequencies from the red planet.
Modern methods of research in the SETI program include the use of ground and orbital telescopes, large radio telescopes with distributed data processing.
However, some are cautious about such attempts of humanity to get closer to the representatives of extraterrestrial civilization, because this can attract unnecessary attention to our planet ...
So, the cosmologist Stephen Hawking recalls that the history of mankind already knows the cases and results when the less developed in the technical plan of civilization collides with the more advanced one.
