Science is a dangerous thing.
Considering how many risky experiments on himself had to endure our long-suffering planet, it’s amazing she’s still alive.
The Kola superdeep borehole
The Kola superdeep borehole located in the area North of the Arctic circle in the most North-Western point of Russia and is the deepest underground passage dug deep in the Earth.
Soviet scientists initiated the drilling of the well in 1970 and by 1989 reached the level of 12 262 meters.
They wanted to drill the earth’s crust and reach the upper layer of the mantle, but had no idea that it could face. However, fears about the formation of large-scale earthquakes or the appearance of demons from Hell proved to be unfounded.
And work on the project was discontinued due to the fact that at the end of the passage the temperature was so high that molten rock flowed back into the hole, not allowing the scientists to increase the depth of drilling.
Test Trinity
The Trinity test was part of the American program “Manhattan Project” to develop nuclear weapons. This test on 16 July 1945, was the world’s first explosion of an atomic device.
The initial development of weapons of a new era was delayed a bit due to concerns of the scientist Edward teller, who took part in the project. He assumed that the detonation of a plutonium charge of such power may lead to the initiation of self-sustaining chemical reactions involving nitrogen, which theoretically could lead to uncontrolled ignition of the Earth’s atmosphere.
However, further calculations showed that the possibility of such a scenario is extremely small, so the work continued. The resulting first nuclear test the explosive power is estimated at 21 kiloton of TNT.
The explosion of this device reminded the project leader, Robert Oppenheimer, the line from the Hindu sacred manuscript: “Now I like Death, the destroyer of worlds.”
The large hadron Collider
When scientists 10 Sep 2008 officially announced the creation of the Large hadron Collider project, some have come to believe that this device will lead to the destruction of the world.
The project of the particle accelerator over 6 billion dollars was created for the acceleration of proton beams in a 27-kilometer tunnel loop with subsequent pitting, which leads to the formation of microscopic black holes, which are believed to be appeared immediately after the Big Bang.
Some believed that the result of the experiment, black holes will grow uncontrollably until the Earth is engulfed. However, scientists dismiss these rumors, as it is estimated that each black hole has a limit, after which it evaporates. This phenomenon is known as Hawking Radiation.
“Starfish Prime”
The magnetosphere of the Earth is an important protective layer, which are charged particles that protect earth’s atmosphere from the damaging effects of the solar wind. And that would be if a large nuclear bomb explodes in the magnetosphere?
The United States and decided to find out in 1962. Well, among other things, the purpose of the experiment was to find a way to intercept Soviet nuclear warheads still in orbit.
Therefore, initiated the explosion of a thermonuclear warhead at an altitude of 400 kilometers above Johnston Atoll in the Pacific ocean.
The blast yield of 1.4 megatons was visible from a distance of 1450 kilometers in the Hawaiian Islands, where an electromagnetic pulse damaged light lines and telephone communication.
Also on the lower earth orbit formed an artificial radiation belt, which is kept for five years and has damaged more than one third of all that was in the satellites.
The SETI project
The project search contacts with “extraterrestrial intelligence” (“Search for Extraterrestrial Intelligence”) includes a complex of measures on detection and attempts communication with representatives of extraterrestrial civilizations.
In 1896, Nikola Tesla suggested that radio could be used to establish contact with aliens. In 1899, he thought he even received signals from Mars. In 1924 the United States government declared a “national radio day” between August 21-23, 1924, when scientists were able to scan the air in search of radio frequencies from the red planet.
Modern methods of research for the SETI program include the use of ground-based and orbiting telescopes, large telescopes with distributed data processing.
However, some cautious attitude to such attempts by humanity to approach the representatives of extraterrestrial civilizations – because it might attract unwanted attention to our planet….
So, cosmologist Stephen Hawking reminds us that human history knows cases and results when less developed in technical terms, civilization is faced with a more advanced
