For a huge comet of 500 trillion tons, the Earthlings do not know how to meet this alien, he should not be a diamond-rich comet, when will it fly to The Earth? Here comes the truth
Is this giant comet Bernardinelli? Bernstein discovered, and therefore named the comet after him, which is 50 times the size and weight of ordinary comets, up to 80 miles in diameter, and it was seen through hubble and published in the authoritative journal Astrophysical Journal. At the beginning of the Zhou Dynasty, some people in China began to observe astronomy, and night stargazing is still used today.
The deterioration of the Earth's environment, especially the melting of polar icebergs caused by carbon dioxide, and the rise of sea levels. Some scientists have cursed the earth with this large comet, marking the extinction of the dinosaurs as a comet hitting the earth, and these scientists have spoken out the fallacy that the earth is going extinct.
NASA had earlier said that the comet would not hit Earth without panic. Looking back at the 100 years of human development after the second industrial revolution, the rate of species extinction has indeed accelerated, and the climate change has been obvious. The probability of natural disasters has increased, and the damage to the environment in the case of chemical pollution is enormous.
The extinction of dinosaurs has stimulated to a certain extent the sense of concern for the destruction of the environment, the Earth Hour and the mid-century to achieve carbon peak carbon neutral global task, are practical and gradually achieved goals, garbage classification let the next people understand that environmental protection is very important.
Scientists have found that this huge satellite is still shining, it is 3 billion kilometers away from the earth, 1.6 billion kilometers away from the sun, at the current speed, at least until 2031 to reach the earth, do not worry too much.
The comet is a dirty snowball composed of water, methane and solid dust, under the radiation of the sun, it will quickly turn into a light, like a broom, the Chinese record of the heart appeared in the Spring and Autumn 613, more than 600 years before Europe, although the heart is powerful, but the impact on the earth has never occurred.
When the comet is far away from the Earth, its volume will be very small, and when it is close to the Earth, the volume will become very long. Up to 200 million kilometers. This is the result of close contact with comets observed by space rockets, artificial satellites and spacecraft, and the surface of WeChat is wrapped in a cloud of hydrogen atoms.
The main component of the comet is water, the comet is composed of two parts, the comet has a cometary nucleus, and the hard material in the center is water and dust, and iron solidifies together, there is no imaginary diamond at all, the largest nucleus center is more than ten kilometers in diameter, and the smallest is also hundreds of meters.
The 500 trillion-ton comet was first discovered in 2010, when its size was unclear due to distance, and on January 8 of this year, scientists took five photos of it through the Hubble telescope to finally determine its size, and the initial continuous observation was made to make references for predicting natural disasters.
Comets are objects made up of ice and dust around the Sun, and the right distance avoids the comet from vaporizing and disappearing, and the temperature of the comet's surface is the same as that of ice. What confuses scientists is that what is the material of comet natural ADHD, which emits light after approaching the sun?
Scientists predicted that a comet hitting the Earth would destroy a million-person city in an instant, and this huge comet was bound to cause the secret of the race. Scientists also need to pay attention to its trajectory and distance from the earth, and prevention is the mainstay. At the same time, it is also to protect the satellites operating in orbit from destruction.
Humans will not go extinct like dinosaurs, and the extinction of dinosaurs is not only due to environmental changes, but also from the struggle between species. It is the law of survival of the fittest in biological evolution, human food diversification, did not lead to the break of the food chain, causing ecological imbalances, resulting in global warming and uninhabitable.
At present, human beings have realized the harsh consequences of environmental warming, and are actively exploring outer space, looking for a second earth suitable for human survival, with the gradual development of the lunar exploration project landing and Mars program, the establishment of the International Space Station and cooperation between many countries, the second home outside the earth will provide new opportunities for human development.
The invention of intercontinental missiles and radio telescopes, especially laser weapons, will provide powerful weapons for humanity to quickly wipe out comets that attack Earth.
Any rumor stops at the wise, we must believe in science, do not exaggerate the disaster caused by the comet hitting the earth, in today's developed self-media, personal speech should be rigorous, which is also the bottom line and principle that social citizens should adhere to.
Creating a good and positive social atmosphere is the starting point for every network self-media person to create value, and shooting stars cross the sky, and we will always make beautiful wishes. For comets we don't have a black-and-white one-size-fits-all approach.
