If humans were to bring back a large amount of resources from the moon to Earth, what would be the i

Transporting too many resources will lead to a decrease in the mass of the moon, and the gravitational force between the moon and the earth will be out of balance, causing the moon to break away from the earth, and the tides and magnetic fields on the earth will undergo major changes.

It will affect the normal operation of the earth, after all, a large number of resources greatly increase the burden of the earth's operation.

Whether there are resources on the moon that can be used by human beings remains to be considered, and if there are resources that can be used, then it must be a great wealth for the earth

What would happen if humans brought back the vast resources from the moon to Earth?

The moon has iron, aluminum, zinc, silicon, potassium, phosphorus, titanium, magnesium, manganese, chromium, rare earths, natural glass, oxygen and water necessary for human survival, and it is conservatively estimated that the lunar surface contains more than 700,000 tons of helium-3. These resources can be used on Earth for 7,000 years.

In particular, HE 3, which is a representative of the future of human energy, is much more dense and efficient than fossil fuel energy. When it comes to resources on the Moon, the first thing that comes to mind is helium-3.

However, if helium-3 is used for nuclear fusion, neutrons will not be generated, and the corresponding radiation protection will be eliminated. There are very few reserves of helium-3 on Earth, but there are very many on the Moon, because the Moon is not protected by an atmosphere and magnetic field like the Earth, and the helium-3-rich solar wind has been bombarding the Moon for billions of years and leaving helium-3 behind. According to rough estimates, there are at least 1 million tons of helium-3 on the Moon, and only 100 tons of energy needed to generate enough energy for the whole world to use for a year!

It can be said that as long as the technology can be reached, helium-3 on the moon can basically completely solve the energy problem of mankind.

In addition, the natural environment on the moon is a resource in its own right. There is no atmosphere on the moon, and sunlight directly hits the surface of the moon without loss, so if a solar power plant is built on the moon, the power generation efficiency will be significantly higher than that of the earth.

The gravity of the moon is only 1 6 of the earth's, and the surface is a vacuum, such an environment will be of great help to many scientific experiments, and will significantly promote the development of materials science, chemistry, physics and other disciplines. There is no atmosphere on the Moon, there is no effect of atmospheric jitter for astronomical observations, and the clarity of images taken by telescopes of the same size will be significantly better than that of Earth. In addition, without an atmosphere, even if the sun is in the sky, the sunlight will not be scattered and the starlight will not be drowned, and optical observation can be carried out around the clock.

Of course, space telescopes can do this, but in the future, if there is a full-fledged lunar base, it will be easier to build and operate large telescopes on the lunar surface than in space. I think this advantage can also be counted as a resource of the moon.

In the longer term, humanity will eventually move out of the earth and into the vast solar system. At that time, the Moon would be an outpost, or transportation hub, for humanity to interplanetary space.

For example, if we were to travel to Mars, travelers from different parts of the planet could first assemble at a lunar base (whether on or in lunar orbit) and then embark on a longer voyage from the moon.

We know that the moon is a satellite that revolves around the earth, and the mass and volume of the moon are not as large as our earth, but the importance of the moon to our earth is also very much, for example, the moon will affect the tidal movement inside the earth, if there is no moon, the tides inside the earth will no longer be so regular. However, in the seventies and eighties of the last century, Armstrong completed the first moon landing mission in the United States, and Armstrong's small step represented a big leap for human civilization. And in recent years, scientists have been exploring the moon and found that there is a lot of material on the moon.

The main answers are as follows.

First, it will consume a large number of spaceships. First of all, the first point is that it will take a lot of time and effort to make extraordinary. We know that although the moon is very close to our earth, its distance has reached tens of thousands of kilometers, and the spacecraft and fuel required for these tens of thousands of kilometers are very huge.

This is very terrible for the consumption of a country, so no country can accomplish such a task, and if there is a group of countries that want to complete or want to study this aspect, it will definitely arouse the dissatisfaction of other countries, which is likely to cause international disputes.

2. Bring some cosmic microorganisms or germs back to Earth. Secondly, and the other point is that we cannot guarantee that the moon is free of any bacteria or microorganisms. It is very likely that there will be some microorganisms or viruses from other planets on the materials we bring back, which is undoubtedly a very difficult thing for us humans.

Because the current human technology is difficult enough to solve the virus of the earth type, let alone a virus on other planets.

3. What impact will these resources have on the moon if they are transported back to Earth is something that scientists are considering. The last point is that if these resources are really transported back to Earth, what will happen to the impact on the moon after these resources are reduced, whether it will cause the moon to deviate from the earth, or cause the mass of the moon to decrease, which is a question that scientists have to worry about.

There seems to be a problem with the solution on the first floor, but note that the title says that the mineral deposits of the moon are transported to Earth. Let me describe it quantitatively.

The gravitational pull of the Moon moving around the Earth is provided by the centripetal force:

f=gmmr -2=m*omega 2*r, remove m and deform it, you can get it.

omega=sqrt(gmr^-3)

Because the period t=omega*2pi, that is to say, t=2pi*sqrt(gmr -3), is related to the mass of the earth and the distance between the earth and the moon. Therefore, if the mineral deposits on the moon are brought to the earth, the orbital period of the moon will increase (of course, depending on the quality of those ores, if the mass can be ignored, the orbital period does not change).

According to the gravitational force formula, it is equal to the centripetal force formula, and the mass of the satellite is eliminated, so the data of the period has nothing to do with the mass of the satellite, but has a relationship with the speed

The period of the Moon's motion around the Earth should be shorter, and the answer above is wrong!!

In the solar system, the Earth-Moon system is a very magical combination, and the Moon is like a "goddess of luck" for life on Earth. Don't say that without the moon, even if the moon changes a little, for example, the orbit of the moon is not in its current position, or the volume of the moon is not as large as it is now, the earth will fall into disaster, and life on the earth, including human beings, will cease to exist.

This is by no means sensational! Our moon seems to be almost perfect at the moment, with an appropriate orbit around the earth of the right size and distance just enough to stabilize the Earth's orbit. In order to simulate the possibility of life in the planetary system, cosmologists entered the volume data of the moon slightly (10% smaller in volume) into the computer, and the computer program showed that because the volume of the moon became smaller, it would cause a little oscillation in the rotation of the earth, but even if it was a small oscillation, the amount would slowly accumulate over millions of years, so that the shaking of the earth would reach an uncontrollable point, and the axis of the earth would move 90 degrees in hundreds of thousands of years. This would have catastrophic changes to the Earth's weather system, and if this phenomenon had occurred before the birth of life on Earth, there is no doubt that life on Earth would not have been possible. If it were to happen now, drastic climate change would also wipe out all life on Earth.

Although the above is hypothetical, another real change in the moon is taking place. Astronomical data show that the Moon is moving away from the Earth at a rate of 4 centimeters per year due to tidal forces, and in tens of millions of years, the distance between the Moon and the Earth will double the distance from the current one, and the farther away it is, the faster it will leave. At that time, the Earth will no longer be able to maintain a steady rotation, and this constant instability will cause the Earth to roll in orbit, the Moon will no longer be visible in the night sky, the constellations will be completely different, the weather will be extremely bad, and life on Earth will either leave or perish.

The moon is completely separated from the gravitational pull of the earth, then the earth's trouble is big, the earth's axis of rotation and the inclination of the orbital plane will become unstable, no longer maintained, without the gravitational pull of the moon, the inclination angle can reach a maximum of 45 °, and the climate in all regions of the world will have earth-shaking changes

There are some effects on the earth, such as the most obvious is that the earth's rotation will be slower and slower, there is almost no tidal action, no solar eclipse, no lunar eclipse, will never have a fatal impact on the survival of human beings, but the probability of the earth being collided by objects in other universes will increase significantly, because any extraterrestrial objects that approach or try to approach the earth will pass through the gravitational field of the moon, and most of them will be attracted by the moon to protect the earth.

The earth and the moon are formed by the same nebula after the universe is large, due to the effect of the celestial physical field, the two did not converge to form a whole, but were torn into two pieces, forming the current earth and the moon alone, because the volume and weight of the earth are much larger than the moon, so later the moon under the action of the earth's gravity, gradually became a satellite of the earth, and the "same root brothers" have been with the sky for billions of years.

If one day the Moon asks the Earth to become an asteroid in the solar system, since it becomes an asteroid from near the Earth, its orbit is very close to the Earth, and the period is almost the same. It is to make hundreds of millions of years later, the moon will be re-bound by the earth's gravity, and it will be a trivial matter to become an earth's satellite again, and if it is installed on the earth, it will be the end of the world that bacteria cannot escape.

The Moon may have been a planet in the solar system or an alien galaxy before, but unfortunately fell into the force field of the Earth and the Sun, and gradually became a satellite of the Earth after being "conquered" by the Earth. But this "couple" has never been in close contact since they "met" and lived next to each other, and their mutual repulsion has made them only "look at each other" instead of "holding hands", and for billions of years, they can only silently endure the cruel arrangement of God.

The Earth's rotation rate is gradually slowing down, the Earth's days are getting longer and longer, and eventually the Earth's rotation will be slower and slower.

The day will get longer, and the daylight will get longer and longer, and the phenomenon of polar day is likely to occur.

By the time it moves away from the Earth, the Sun will probably become a red giant, and the Earth will have already been swallowed.

With earth-shaking changes, the earth may not be in the dark, and it may not be cold.

Without the Moon, life on Earth would probably not exist.

According to scientists, the Moon is three centimeters away every year because the Sun's energy decreases, causing the Moon to move away constantly. The moon was called the moon in ancient times, it is one of the moons of the solar system, the area of the moon is about 1 4 of the earth, the mass of the moon is equal to 1 80 of the earth, the surface of the moon is covered with craters of various shapes, formed by the collision of meteorites, the distance between the moon and the earth is about 300,000 kilometers. <>

According to modern scientific research, the difference between the moon and the earth is that from the moment it was born, it has been far away from the earth, although it is only three centimeters per year, everyone thinks it is small, but the accumulation time is very long, especially from the day there is a moon, until now, the distance from the earth is very large, at the earliest, the moon is only about 2-30,000 kilometers from the earth, on the earth, people can fully see the topography of the moon through the naked eye, and today, Accurate observation of the Moon is possible only with the help of advanced lunar equipment technology or lunar probes. <>

Why is the Moon moving away from the Earth? The reason could be that the motion of the Moon is related to the angular momentum of the Earth, because the rotational energy inside the Earth is preserved, and the energy does not disappear on its own, but is transferred to the Moon, causing the Moon to have more rotational energy, resulting in the continuous absence of the Moon and the Earth. There is also a possibility that as the energy produced by the Sun decreases, it will have a great impact on the Moon, because the Sun is not a real star and there is a constant need for nuclear fusion in it, so every day the mass of the Sun decreases, causing its gravitational pull to decrease.

causes the Moon to gradually move away from the solar system. <>

The Earth's magnetic field is most likely related to the gravitational pull of the Moon. If it weren't for the Moon, the Earth might turn into a planet without a magnetic field, like Venus. The importance of the Earth's magnetic field to life is very important, for example, the solar wind and cosmic radiation are intercepted by the Earth's magnetic field, without which life on Earth cannot exist, and the moon is like an umbrella that intercepts many asteroids and meteorites that should have fallen on Earth.

If it were not for the Moon, the likelihood of an Earth collision with interplanetary matter would have increased considerably.

According to scientists, the Moon is moving away from Earth at a rate of 3 centimeters per year due to the decline in the amount of the sun's energy, which causes the Moon to stay away from Earth all the time.

The ancient Moon, also known as the Moon, is one of the moons in the solar system, the area of the Moon is about 1 4 of the Earth, the mass of the Moon is about 1 80 of the Earth, the surface of the Moon is covered with various forms of ring mountains It is formed by various meteorites, and the distance from the Moon to the Earth is about 300,000 kilometers.

Secondly, according to recent scientific research, the Moon is very different from the Earth, because since the birth of the Moon, the Moon has been far away from the Earth, although it is only 3 centimeters per year, we feel small, but the long-term accumulation, especially so far, the lunar day is very far from the Earth, and soon, the Moon is only 20,000 to 30,000 kilometers from the Earth, where one can see the surface of the Moon completely with the naked eye, but now it can only be seen with the naked eye with the modern technology of a lunar lander or lunar probe that can be observed precisely.

Why is the Moon moving away from Earth? The reason could be the angular momentum of motion of the Moon and the Earth, because the energy cycle inside the Earth is preserved, and the energy does not disappear automatically, but is transferred to the Moon, resulting in the Moon being greater than the rotational energy, which causes the Moon to move away from the Earth. It is also possible that the Sun will continue to produce energy, and it will also have a significant impact on the Moon, because the Sun does not belong to the true meaning of the star, and there needs to be continuous nuclear fusion inside, therefore, the mass of the Sun decreases every day, causing its gravity to continue to fall, gradually moving the Moon away from the solar system.
