The Moon is located about 380,000,000 meters from the Earth, has a mass of about 22 kilograms multiplied by ten, and has an average rotational speed of about 1,023 meters per second. If the Moon were to hit the Earth, its current kinetic energy and the gravitational potential energy between the Earth and the Moon would be released on Earth.
The kinetic energy of the Moon's rotation alone is 27 joules multiplied by ten, and if the gravitational potential energy between the Earth and the Moon is added, the kinetic energy of the Moon when it hits the Earth is two orders of magnitude higher. The release of so much energy onto Earth would melt the Earth's surface and the entire Earth would turn into a sheet of red-hot magma.
If the Moon hits the Earth, it is certain that life on Earth will die out instantly. In fact, it is not as big as the moon, even if a meteorite with a diameter of 10 kilometers hits the earth, the environmental climate deterioration caused by the violent impact can also lead to the extinction of a certain species. The extinction of the dinosaurs 64 million years ago was actually caused by a 10-kilometer meteorite impact.
How much more about a moon that has a quarter of the earth! It is estimated that the earth can be shattered into slag.
How can humans survive in this situation? In fact, just like human beings living in a building and being hit by a stone that owns a quarter of a house at a speed of 30 kilometers per second, human beings will certainly not be spared, and the only way is to move outside the building, the farther away the better. In other words, the earth was hit by the moon, and the farther away the better in a spaceship, so that humanity could survive.
There is no possibility of survival if you stay on Earth.
If it really comes to that day, the level of human science and technology should be many times higher than now, with the improvement of the level of science and technology, personal spacecraft will definitely be popularized, and then human beings should also find a planet suitable for living creatures, even if there is no planet suitable for human habitation, human beings should also build a large living space station in the universe.

The impact of the Moon on Earth will occur:
1. The collision of planets can produce volcanic eruptions, rising water levels, reduced oxygen levels in seawater, and rapid climate changes, leading to the death of a large number of organisms.
2. After the collision, the force of ** is equivalent to the 12th magnitude of the Richter earthquake, which is one million times the most intense ** on the earth, and the dust and carbon dioxide ejected by the volcano will produce greenhouses for shelter and annihilation, so that the earth's temperature will rise.
3. Dust also blocks sunlight, so that plants cannot produce photosynthesis and destroy the earth's food chain.
4. "Small" asteroids crashing into the earth will also cause "extensive damage" and human life**, and the skin will die quickly.
5. Collision with the earth causes a huge disaster on the entire earth, and a large amount of dust and debris generated by the collision enters the atmosphere, causing environmental combustion and catastrophic changes.
-
Excluding any possible external factors, according to the laws of nature, it is impossible for the Moon to collide with the Earth in the future.
The Moon is a natural satellite of the Earth and the fifth largest moon in the solar system. Because the tide is locked, its rotation is synchronized with the revolution, so it is always facing the Earth. Many countries are interested in lunar exploration, among which the United States is the first country to achieve a manned landing on the moon, and recently China's Chang'e-4 completed the first human landing on the far side of the moon, and also did biological experiments on the moon, successfully cultivated a young shoot on the experimental vehicle on the lunar surface.
The Moon revolves around the Earth in an elliptical orbit, and one rotation is the sky. According to scientists' observations, the Moon is not only not colliding with the Earth, but is getting farther and farther away from the Earth. The Moon is moving away from the Earth at a distance of about 4 centimeters per year, and in the long run, the Moon will only be farther away from the Earth in the future, and it is impossible to collide with the Earth without the intervention of other external forces.
So the problem you're worried about is not going to happen. Unless there is a huge external force pushing the moon towards the earth, such a thing as a collision is possible, who has the ability. There may be no other possibilities other than advanced extraterrestrial intelligent life.
If it is a meteorite impact, not to mention the direction of force, those small meteorite impacts are useless. In the case of a large meteorite, the chance of hitting the moon is very small, and even if it hits, it will have no effect once or twice, and it depends on which direction it hits. It must be a continuous impact in roughly the same direction to push the moon towards the earth, you must know that the moon is not small, after all, it is the fifth largest satellite of the solar system.
As long as there are no high-level aliens to play tricks, the moon will not hit the earth, it will only drift away from the earth.
-
Summary. No, although the vast majority of lives will pass away, there are always those who survive, of course, for a larger life like a human being, it is not so optimistic! But even so, it is unlikely that the power generated by the impact alone will wipe out all mankind, after all, with the scientific and technological power that humans have, it is still possible to survive, but only a very small number of people can survive.
No, although the vast majority of lives will pass away, there are always those who survive, of course, for a larger life like a human being, it is not so optimistic! But even so, it is unlikely that the power generated by the impact alone will wipe out all mankind, after all, with the scientific and technological power that humans have, it is still possible to survive, but only a very small number of people can survive.
And I'm sure it's not going to happen.
Why. Because the Moon is a satellite of the Earth, the speed of the Moon and the distance from the Earth form a basically perfect dynamic balance, and if you want to collide, you must have a very large external force.
That is, it has to change its trajectory.
And when you want to collide with the plane, you can only face to face, and there is always a small range of impact on the back.
-
No, the Moon, as a satellite of the Earth, does not have a common orbit between the two, so they will not collide. And according to scientists, on the contrary, the moon is gradually moving away from the earth. When the Moon brings tides to the Earth, the highest point of the sea (and crust) will be slightly later than the Moon due to the resistance, and the gravitational pull of this angle will attract the Moon and slow it down.
The angular momentum expended is compensated by the Moon moving away from the Earth. In fact, in the early days of the formation of the Earth and the Moon, the Moon was much closer to the Earth than it is now, and the revolution of the Moon and the rotation of the Earth were much faster than they are now. For example, the Earth's rotation time in a century will be slower by seconds, but the Moon will be faster.
It is about centimeters away from the Earth every year.
<> without external factors, accidents are very difficult to happen. Something as big as the sun and helium flashes were on the agenda. The helium flash is as follows:
Stars use their gravitational pull to twist hydrogen into helium and maintain equilibrium by fusion, but problems arise as hydrogen is consumed and helium accumulates. Because there is enough space inside the star for hydrogen fusion, not helium fusion, the fusion reaction slows down and the nucleus begins to contract. As the volume shrinks, the internal pressure increases, and the helium in the center is compressed into a state of relaxation in the simple key.
This degenerate state is the key to helium flashing, and you can think of a helium flash as electrons being squeezed to nowhere to move, like a super pressure cooker. When the mass of the star is between times the mass of the Sun, the pressure inside the cooker increases as it contracts, eventually igniting helium fusion. The fusion of helium is violent, short-lived, and is known as a "helium flash" Considering the mass of the sun, helium flashes are unavoidable, but earthlings do not need to worry about them.
Because helium flashes occur in the red giant phase, the Sun was already a red giant long before the helium flash, and the Earth also turned yellow. All in all, it is not scientific enough to use helium flashes as a reason to leave the earth.

If it is in the near future, humanity will be done with no other possibility, and now even if the possibility of finding a suitable planetary immigrant is 0% There are many problems that cannot be solved:
1: To launch a spacecraft, you need to reserve 3 times more fuel than the spacecraft itself (because you have to have enough energy to fight the earth's gravity, of course, the current technology may not need so much, but it is a lot right), and it is even more impossible to take a dozen people out now, even if you use gravitational catapults, you will end up like a traveler, floating without fuel and waiting for death.
2: Radiation Out of the Earth's atmosphere means resisting the high-energy radiation of the sun and the universe Not everyone can withstand it for a long time (in addition, when approaching Jupiter and Saturn, there will also be very strong and strong radiation, at that time, Voyager 1 had to hang on Jupiter if it was not strong protection), so the protection of people is also a big problem.
3: Gravity We are used to the gravity of the earth If we can live on Mars, we will not live long if we go to Mars, because it will cause some diseases if it is quite different from the gravity of the earth, and the space shuttle has no gravity in the universe Eating and drinking are problems Civilians do not have the training for so long Even professional astronauts have to play for a long time in the universe. So the space shuttle must also have a gravity system as strong as the Earth inside.
4: Speed 10,000 miles of light per second It takes four years to get to Proxima Centauri (the nearest Huan star) Tianyuan 4 10 light years Vega 25 light years These are all close But these also confirm that there can be no planet similar to the Earth You have to reach this speed if you can't get a wormhole How many generations do people have to live on a ship to achieve it Even if you get close to the speed of light will produce time distortion But the Huan star flying hundreds of light years away is also played in the distortion generation Even if the 100 years of the speed of light is someone else's nn years, it is only for others Contemporary people have to finish playing on a boat, and the speed of light is constant, and it's only getting closer and closer, and it's impossible to go beyond it, just like time can be distorted, it can be elongated, it can be shortened, but it can't be reversed, and that's the theory of relativity.
You can think about these problems for the time being, so it's up to everyone to protect the earth, don't look at the fact that we know a lot about the universe now, but there is still no way to immigrate in the short term, so the earth is gone, and we are done.

Some people in Qiguo were worried that the sky would fall and the earth would fall, and he would have nowhere to live, so he couldn't sleep well all day and couldn't eat.
In modern times, some people are worried that the moon will hit the earth and all mankind will die Marxist philosophy tells us that everything in the world will die one day. Whether it is a small microorganism or a large universe, there will be a day of extinction, which is the law of nature.
It is impossible to hope that something will last forever.
The growth of human beings is more than 100 years, the history of human existence is 3 million years, and the birth of civilization is no more than 10,000 years; The interstellar evolution is based on billions and tens of billions of years. Don't you think your thoughts are any different from unfounded worries? It is better to think about how to get human beings into space in a shorter period of time, otherwise the human species will be destroyed before the "moon hits the earth".

First of all, the moon is moving by the gravitational pull of the earth, and secondly, due to various reasons such as meteorite impacts, accelerated rotation of the earth, etc., the moon is moving away from the earth at a rate of centimeters per year, then we can know that under natural circumstances, the moon will not hit the earth. If the moon falls, it will not fall in an instant (according to the ideal calculation of free fall, even if the moon does not pass through the atmosphere, it will take nearly three hours to arrive) human beings can **, the moon is a satellite, it will not shine and heat, it cannot provide kinetic energy by itself, the process of landing should be similar to that of a meteorite landing on the earth, a part of the volume will be consumed in the atmosphere (if we still have an atmosphere), the larger the volume, the more it will be consumed in the atmosphere, The rest of the part can be smashed by relying on the earth protection network (that is, the artillery ball dedicated to smashing asteroids), and then prepare for air defense on the ground, and humans will move underground, although the surface loss will be large, but human beings are very tenacious, don't worry too much, in the face of cosmic disasters, everyone can still join forces.

It is said that it will get farther and farther away, and eventually break away from the earth, and if it hits the earth, it can be redeveloped!
-
Scientists have measured that the Moon is slowly moving away from the Earth. So there will be no impact on the Earth.
-
This is called, and it is still unfounded. Astronomical observations confirm that the Moon is moving away from Earth at a rate of 4 centimeters per year. So the possibility of the Moon hitting the Earth does not exist.

In fact, this situation is not considered by human beings, and even if it collides, it is from the tangible to the invisible way that human beings cannot see. The visible is the body, and the invisible is the mind that is the energy of the mind. If human beings do not cling to the distinction between the visible and the invisible.
There will be no stance on the visible, and fear of the invisible. And then you won't be caught between being and not worrying. In this way, it is possible to transcend the existence and be completely free.
-
If it crashes, I don't think I need to think about what humans do, I guess if it hits, the earth will be finished.
1.You always doubt her, don't trust her, look at her to death, she feels that she is not free. I went to my ex-boyfriend to complain. >>>More
After reading the reply below, there is no situation. Wearing? Soul wearing? >>>More
Of course, the best friend, in my mind, still depends on the best friend, thinking that he is mine, and his relationship with others is not as good as mine, but when he has a better friend, I will naturally feel that I am abandoned, forgotten and even deceived by friendship, but these things can't be good, so I still live a good life, friends are still friends.
I feel that if I don't have the Internet, I think I will be very anxious, I should choose to sleep to numb myself, so that I don't have time to think about the fact that I don't have the Internet, if I wake up, I think I should go out to the street to buy clothes or eat, so that I can get through the day quickly.
