Scientific experiments that endangered the Earth | Digital Trends Spanish

Science must be at the service of the progress of humanity and the development of knowledge. However, throughout history they have developed scientific experiments dangerous –And some questionable– which, fortunately, did not destroy the Earth.

You will be interested in:

Trinity test

On July 16, 1945, the United States carried out the Trinity test, the first nuclear weapon detonation in history. The experiment was conducted in Alamogordo, in the New Mexico desert, and was carried out less than a month before the atomic attacks on Hiroshima and Nagasaki in World War II.

Although the test allowed to verify for the first time the theories of the physicist Hans Bethe, in that it was mathematically “almost impossible” for a nuclear bomb to ignite the atmosphere and destroy the planet, its realization caused concern even among the scientific community.

Soviet biological weapons program

The former Soviet Union covertly developed the largest biological weapons program between 1920 and at least until 1992, even violating the 1972 International Convention. It is known to have developed eleven biological agents, but has performed on many more. One of the best known incidents was the leak of spores of Bacillus anthracis (the causative agent of anthrax) from a military installation in Sverdlovsk recorded in 1979. At least 66 people died, although the total number is unknown because the KGB destroyed the evidence .

Starfish prime

On July 9, 1962, the United States detonated a nuclear bomb at an altitude of 400 kilometers, in an area where the International Space Station (ISS) is located today, with the aim of blocking Soviet missile systems. It was a 1.44 megaton W-49 thermonuclear warhead, the largest ever detonated in space. The test created a radiation belt around Earth that lasted five years, affecting low-orbiting satellites, and damaging telephones and electrical systems in the process.

Kola Superdeep

Measuring 12.2 kilometers long and 23 centimeters in diameter, the Russia’s Kola Superdeep is the world’s deepest science hole. The project aimed to study the Earth’s mantle, the layer located about 30 kilometers below the surface. It was suspended after the rotor locked due to temperatures reaching 260 ° C. Although it does not represent a threat to humanity, at first it was feared that the work could cause seismic movements and, even, others believed that it could release got damn…

Large Hadron Collider (LHC)

The Large Hadron Collider (LHC) is the largest and most energetic particle accelerator in the world. It is located in a tunnel of 27 kilometers in circumference 175 meters underground, on the border between France and Switzerland. Its commissioning required the participation of more than 10,000 scientists and is considered the largest machine and the most sophisticated scientific instrument.

Most of the conspiracy theories surrounding its construction, such as being responsible for earthquakes or attracting asteroids to Earth, have been disproved by the European Organization for Nuclear Research (CERN). The agency has also ruled out that it could cause black holes like those in space, although it did not rule out quantum black holes. “The observation of such an event would be exciting to understand the Universe and it would be perfectly safe”, said the entity.
