How will the earth end?These 5 ways, each one thinks about it
Author:Astronomy online Time:2022.07.12
It can be said that humans always rely on the earth. In our cognition, the earth has existed billions of years, so it will last sustainable. But we also know that all beings are equal, and the blessings are between the night. This is beyond doubt.
Under normal circumstances, we will not consider the impermanence of changes in the earth at all times. Not even thinking of creatures, especially human beings, need to maintain a quantity for survival, and the guarantee of the guarantor and nature in order to survive. Humans will not suffer an endless living crisis, so we don't have to worry about it. However, human existence is rare, because there are various factors that non -human capabilities can be performed inadvertently.
For example, our current level of science and technology cannot accurately predict earthquakes, hurricanes and even astronomical disasters.
Before these incidents occur, we can of course strive for a little time for ourselves, such as measuring nearby earthquake activities or research weather mode. But we ca n’t say sure to say: what kind of natural disaster will happen.
Throughout the ancient and modern, most species have paid a considerable price in the world's exterior incidents and learned to prepare for survival. More than 99%of all creatures on the planet have become extinct, and most of them have been extinct in various events in the past. There are also more animals who have extinct more than 3/4.
More and more scientists believe that we are now in a new world extinction. Nevertheless, under the huge climate change that really affects the living conditions of biology, the creatures on the earth will have a period of time -sometimes for thousands of years -unnecessary changes on the earth, and try to adapt to changes.
What is worse than climate change is that the earth terminates the subject of life in an instant. This is not alarmist. The planet is indeed flexible, but if one planet collides with another planet, then this planet will suffer a devastating blow.
Now, we don't want planets like Mars or Venus to attack us in the short term, but in fact rogue planets are very common in the universe.
A paper at the University of Cornell speculates that the number of these willful celestial bodies in space is twice that of stars, and other studies are expected to be hundreds of thousands of them. Therefore, there is a very small possibility that one day a planet unknowingly enters the solar system, and if this happens, it also has extremely small possibilities to cross the earth's orbit. This is what scientists do not want to happen, but if it happens, at the same time, if its volume is large enough and the key is in the middle, the earth will be destroyed in a short time -it is hit into the once of the rock wreckage.
In today's world, we know that there is a hooligan planet about 80 light years away from us, and its quality is about 6 times that of Jupiter. Some people think that it is not in our direction, but it is said that it has entered the solar system and moved towards us. If so, then we have almost no ability to resist it!
In general, rogue planets are infamous scientific problems ... Because they have no mother star and no light illuminate them, it is difficult to observe and track, which means that there are more hooligan planets in the universe! If a planet breaks into a corner of our universe, the earth will face another possible result. Assuming that the earth is lucky enough to turn into dust from the front of it, the other possibility is: this new planet destroys our original track and completely expel us from the solar system -turning the earth into a hooligan planet! It's hard to say which result is worse!
In addition, the earth may go to the end in a more incredible way, that is, in the black hole. This is a hypothetical scene, but it may be closer to reality than what we think. At present, Black Hole is still one of the biggest unknown in science -it violates most of our current understanding of physics, but we know that if it is close to the solar system, nothing can be separated from its gravity, the earth, the sun, and others Everything will become its victim. Our planet will fall into the black hole, passing through the horizon towards the strange point, and finally completely collapse.
We are actually safe because there are no black holes near us, right? Hmm ... yes, but not necessarily.
According to a survey released in May 2020, scientists discovered a black hole through the Lasian Observatory in Chile, and we only had 1,000 light years from us. From the perspective of astronomy, it was actually a "neighbor next door".
The important thing is that this specific black hole is still not enough to cause us any problems. But it is indeed a "dark" black hole, which means that it is because of the abnormal behavior of other stars around it, and it is discovered instead of the method of sucking the accumulation through conventional observation.
According to the Lasian Observatory team, this means that there are other black holes like it, still waiting for being found, and may be closer to us. However, if this is true, this is not good news! Even so, it takes some time to be swallowed by the black hole; although the unfortunate destiny of the earth is immediately sealed, the actual process will be long, and it will not happen overnight.
Suddenly, it happened in the last minute, we are here in the next minute, we are not here for the next minute ", and then the vacuum decline. In theory, it is possible that the universe exists in a so -called pseudo -vacuum, in a state of unstable: in some cases, it may become a real vacuum state ... In this case, frankly, it is a disaster. It is a disaster. Sex. If we are in the pseudo -vacuum, if a bubble of a very small vacuum (a more pure and more stable version of the universe) enter, then we, the earth, all other ourselves will inevitably finish the egg. There will be many things that may happen,
No one is a good thing. The basic forces that maintain all things may disappear in the end, all forms of substances may be destroyed, or the entire universe may suddenly collapse, kill all life immediately.
However, the most terrible thing is that physicists believe that if this really happens, it will happen randomly at any time -as a result of an unpredictable quantum rising and falling. In essence, we will still be there at a certain moment, and then disappear in an instant, and we don't know what it has happened (or what is about to happen). This is the fear of existentialism! If this is worried, then please rest assured, physicist Max Tig Mark and philosopher Nick Bostrom have calculated this situation (or in any similar situation) Every billion years.
So the appearance of this possibility is minimal. This is a terrible expectation, but the reality like a nightmare is unlikely. Therefore, the vacuum decay may be the final result of "completely out of all the destructive astronomical events we control", but this does not mean that the matter where humans destroy the earth will not happen, and even this incident is for humans. "Solid". In recent centuries, human beings have experienced unprecedented technological increases, which has improved people's quality of life, but this has also made us continue to live in an unstable environment than ever before. One of the typical examples is nuclear weapons.
According to reports, Albert Einstein said after witnessing the power of nuclear weapons that he did not know what weapons will be used in the Third World War, but the Fourth World War Humans will use sticks and stones to fight against it to fight against each other. What he hinted is that the Third World War is the nuclear war, which will end human civilization with its devastating power. As of 2020, nine countries around the world have broken through the development of nuclear weapons, and the explosion power of these nuclear weapons has added up to bombard the entire earth. In order to warn the state of human civilization, a group of scientists and Nobel Prize winners supervise the end of the world (founded by the "Atomic Scientist Journal" hosted by the University of Chicago)* -a symbolizing human global vulnerability around the world The virtual bell of the indicator.
At the same time, it also considers other threats that affect human survival, such as climate change in recent years. In 1953, after the United States tested their first hydrogen bomb -the second -generation nuclear warhead, the end of the end of the end bell was greatly dialed to only two minutes from the night night. In January 2020, the branch was moved to the position of only 100 seconds at an ion night ... But in all the ending clocks that are considered destructive incidents, the nuclear war will be the most instant destructive event. Although many nuclear explosions are unlikely to completely disintegrate the earth, they will even completely change the atmosphere and environment of the earth irreversible. For example, some hypothesis believes that the nuclear in winter caused by the nuclear explosion will block the sunlight, and this consequences will be the end of the human cognitive humans.
However, nature may also destroy human civilization. Throughout history, past experience has proven that volcanoes are one of the most deadly natural disasters. Although humans are very clear about the threats brought by these natural disasters, they are unable to stop them from happening. When the super volcanic (super volcano refers to a volcano like the American Yellowstone Park or the Toba Lake in Indonesia, its volcanic explosion index is 8, which is the highest level that may occur in volcanic explosion.) More serious.
Once these huge volcanic eruptions, the entire world will be extremely difficult, and may even be unimaginable. The eruption of the super volcano immediately ignited everything near it and directly affected the areas within hundreds of miles. The huge, hot, suffocating volcanic clouds will spread to the world, and may bring the risk of covering the sun again (according to certain theories). When a large volcanic volcano erupted by a yellow stone, the worst case may suffer a long -lasting and thorough destruction. 252 million years ago, similar volcanic eruptions may kill nearly 90 % of creatures on the earth, causing the two-stacked-triple-out extinction incident. Like the nuclear war, although the super volcanic incident is unlikely to cause our planet to crack in half in the physical sense. After a series of extensive and profound environmental changes, it cannot restore its original state. Fortunately, these scenarios -at least this type of scene that we cannot interfere with -it is almost impossible to happen at any time in the future; unfortunately, once this kind of situation occurs, human survival will undoubtedly encounter huge challenges.
In the past 4.5 billion years, it turns out that the earth has strong recovery, but even so, in some cases, it has no power. Nuclear wars or super volcanic incidents will not destroy the stars itself, but the earth we know will immediately disappear. Planet collision can directly change the shape and structure of the earth, and its location in the solar system (if it is still in the solar system). If a black hole suddenly appears near the earth, then our planet will not be able to be inhaled. Once the vacuum declines, okay, that thing is simpler, we can say goodbye to the world in instant. This is the five possibilities that suddenly come to the end of the earth. related information:
[1] Black holes are a area in time and space. The gravity here is extremely powerful, so that nothing (including electromagnetic radiation such as material and light) cannot escape from it.
[2] The general theory of relativity predicts that the quality that is dense can cause time and space to distort and form a black hole.
[3] [4] This unreasonable boundary is called an event horizon. Although the status and situation of the things through it will be greatly affected. According to the general theory of relativity, the vision of the event cannot be observed by external observer.
[5] Black holes do not reflect light, so it is performed like an ideal black body in many aspects.
[6] [7] In addition, Hawking radiation is emitted by the predicting events of the bending time and space quantum field theory, and its spectrum is the same as the black body of the inverse temperature as its quality. For star black holes, this temperature is about one -100,000th of Kelvin, which makes it unable to be observed.
