<h1 class="pgc-h-arrow-right" data-track="1" > meteor fish experiment </h1>
The Meteor Fish Experiment is the largest man-made nuclear explosion in outer space and was designed to test the effects of high-altitude nuclear explosions. The nuclear bomb, which was detonated four hundred kilometers over the Pacific Ocean by the United States at the height of the Cold War, had a nuclear yield of 1.4 megatons, which was a hundred times the equivalent of the atomic bomb in Hiroshima.
The explosion effect was far more than expected, so some scientists worry that the big bang could change the Earth's magnetic field forever, which could catastrophically weaken the Earth's self-protection of cosmic rays and expose the earth to dangerous radiation, gradually destroying the ecology of animals and plants, and increasing the risk of cancer in humans. Eventually, high-energy electrons created a short but extremely powerful magnetic field, instantly paralyzing one-third of the low-orbit artificial satellites, and the Soviet Union was afraid of the United States high-altitude nuclear explosion experiment, so it proposed to ban similar experiments, and finally formed the Outer Space Treaty in 1967 to prevent any side of the space nuclear explosion experiment.
<h1 class="pgc-h-arrow-right" data-track="4" > superbugs</h1>
Scientist Ananda Moham chakrabati has created a bacterium that can decompose crude oil through genetically modified engineering techniques, hoping that it can be used to clean up major crude oil spills, and his experiments have proved that this decomposition of crude oil is efficient and less toxic than some existing means of cleaning up oil pollution.
However, this superbug has never been used outside the laboratory, and the manufacture of superbugs is based on the widespread presence of Pseudomonas in the earth's soil, and people are afraid that it may be uncontrollable once it is released. That's right, chakrabati created this new bacterium 100 times faster than natural bacteria eat oil.
<h1 class="pgc-h-arrow-right" data-track="7" > large hadron collider</h1>
In what may be the largest physics experiment ever recorded, the Large Hadron Collider recreated the moments after the Big Bang, looking for fundamental problems related to the universe through 300 megabytes of high-velocity particle collisions, and the experiment has discovered the Higgs boson, also known as the "God particle", which gives mass to the rest of the particles, and this experiment also reached an artificial maximum temperature of 4 trillion degrees Celsius almost 250,000 times the temperature of the sun.
Scientists suspect that the collision of high-speed particles may create a small black hole to suck the earth all in, and another worry is that the experiment will create strange neutrinos, a hypothetical substance that may cause a chain reaction that converts everything on the earth's wall into strange matter and eventually destroys the earth.
<h1 class="pgc-h-arrow-right" data-track="10" > Kola ultra-deep drilling project</h1>
The Korra ultra-deep drilling project was an experiment by the Soviet Union trying to reach the center of the Earth. Despite all efforts, the drilling depth is only 12 kilometers deep and less than 0.2% of the Earth's core.
Just when the Soviet borehole was not close to the center of the Earth, their massive drilling of the Earth's crust sparked panic about the movement of the Earth's crust, which could trigger a global earthquake or volcanic eruption. Fortunately, no similar events occurred in practice, and the drilling process stopped in 1992 so that the temperature of the ground had exceeded the scorching 300 degrees Celsius by this time.
<h1 class="pgc-h-arrow-right" data-track="13" > rice blast</h1>
During the Cold War, the United States tried to weaponize the rice blast fungus, which had the power to destroy the two most important grains on which more than 40 percent of the world's population depended— rice and wheat— a fungus that produced a disease called rice blast, which wiped out rice that could feed 60 million people a year, and an outbreak of the disease directly caused the 1942 Famine in Bangladesh that killed two million people.
A single infection on a single plant can produce thousands of spores overnight, which can lead to the death of grain if the fungus spreads around the world it could create a famine that affects 3 billion people. Once introduced to a country where rice is the main crop, eradication is unlikely, and it is widely believed that the United States has conducted 31 anti-grain weapons experiments between 1951 and 1969, but samples of the disease were reportedly destroyed in 1973.
<h1 class="pgc-h-arrow-right" data-track="16" > the Mercury and Volcano programs</h1>
Between 1987 and 1992 the Soviet army had experimented with the Earth's tectonic plates as weapons. Achieved by detonating three nuclear bombs on the Earth's crust, this disruption to earth's plates could cause a cascade of catastrophic earthquakes and volcanic eruptions, and lead to the potential risk of damage to the earth's crust structure and thousands of deaths.
The late Venezuelan President Hugo Chávez claimed that the 2010 earthquake in Haiti that claimed 160,000 lives was due to U.S. experiments with similar crust tectonics.
<h1 class="pgc-h-arrow-right" data-track="19" > search for extraterrestrial intelligence programs</h1>
On August 15, 1977, a SETI scientist at Ohio State University was operating the Big Ears wireless telescope when it suddenly detected a strong radio signal, which was exactly the same as the extraterrestrial civilization signal it hoped to receive.
This one is called Wow! The signal may be a significant sign that we are currently discovering aliens. Since then, astronomers have done their best to communicate with extraterrestrial civilizations, and scientists not only receive signals but also send signals to outer space, hoping to connect with extraterrestrial civilizations. But Professor Hawking believes that an alien invasion has the potential to destroy humanity. Because other life could conquer and colonize any planet they could reach, Hawking compared this to the discovery of the Americas in Colombia, which directly wiped out 90 percent of the indigenous population within 500 years.
<h1 class="pgc-h-arrow-right" data-track="22" > plague weapon</h1>
During the Cold War, the Soviet Union made many biological and chemical weapons, including a plague immune to antibiotics, which, once released in public, spread rapidly within days and could claim the lives of infected people.
Vladimir Pasnik was the project leader of the Ultrapure Biological Reserve, but after his defection, he revealed that the Soviet Union was also experimenting with anthrax, Ebola and smallpox weaponization. The catastrophic plague was discovered in the 14th century when it killed more than 50 million people in Europe alone, Europe lost 60% of its population in 7 years, and if the plague was weaponized to kill 60% of Today's Europeans it would mean nearly 500 million deaths.
<h1 class="pgc-h-arrow-right" data-track="25" > trinity nuclear experience</h1>
The Trinity nuclear experiment was the first detonation of a nuclear weapon. Before that, the atomic bomb was only a theory, and scientists were not sure whether it would be successful or not.
However, Nobel laureate Enrico Fermi and father of the hydrogen bomb, Edward Teller, feared that it would be too powerful, and both were members of the project, predicting that the explosion might trigger a self-nuclear fusion reaction of a nitrogen nucleus that would eventually ignite the entire Earth's atmosphere. Despite speculation, the experiment was successfully conducted at the U.S. Air Force Base in Alamogordo, New Mexico.
