How hard is it to destroy the moon?

Actually, it's not difficult, you can sleep in your dreams.

As for the topic of what will happen to the world if the moon disappears, I personally believe that if the moon disappears, the world will not undergo any devastating changes, and our earth world will still exist intact, which can only bring the earth world two aspects of the change of light and rotation speed between nights.

Why? Because, the moon is a satellite of the earth, the formation of the moon is determined by the earth's magnetic field, without the existence of the earth's magnetic field, there would be no existence of the moon today, the earth is the master of everything on the moon, and the moon is the son derived from the earth's magnetic field.

If the moon disappears, it will not have much impact on the earth world, the so-called destructive changes will not exist at all, the earth will revolve and rotate the same, there will be the same ebb and flow phenomenon, the same vitality, the same operation as usual, and there will be no destructive changes on the whole.

However, there may be some changes in the speed of receiving light and rotation between nights, in terms of receiving light between nights, a considerable part of the earth's organisms are living at night, and if there is no indirect light reflection of the moon, then the earth will become pitch black at night, which will bring about the impact of nocturnal survival species. In terms of the rotation speed of the earth, if there is no moon, the traction of the earth's magnetic field on the moon will be reduced, and the earth's rotation speed will be slightly accelerated.

If the Moon disappears, the following changes will occur correspondingly for the Earth – the tidal phenomenon is significantly weakened (before the disappearance, the Sun and the Moon work together, and the Moon is dominant; After disappearing, there is only the role of the sun), and the rotation speed of the earth will also stop slowing down, which does not have much impact on life on earth;

After the moon disappears, the tilt angle of the Earth's axis will not be as stable as it is now. For example, Mars, the neighbor of the Earth, does not have the "locking" of large satellites, and the inclination of the axis of rotation can vary between 13° and 40°, and the change period is more than 10 million years. And without the moon, this current stable state of the Earth's axis will also be broken.

Changes in the tilt of the Earth's axis will affect the interannual variation of the direct point of the sun, thus affecting the Earth's climate. Therefore, without the Moon, the Earth's climate will no longer be stable, and will change periodically with the periodic change of the tilt of the Earth's axis. The impact of this on life on the earth depends on the difference between the tilt of the earth's axis and the current state in the new stable state after the disappearance of the moon, if the tilt of the earth's axis is much larger than the current one, the earth's climate will change drastically in a short period of time, and many species will become extinct because they cannot adapt to this change;

If the moon disappears, then the moonlight will also disappear, which will have a great impact on the growth and reproduction of some organisms, and the biological chain on the earth is interlocking, and a strong blow to one link will also bring a series of irreversible chain reactions, and even trigger the extinction of multiple species.

Yes. If the moon disappears, the earth will deviate from its original orbit, and the environment will change dramatically, so the earth will face a devastating disaster.

Absolutely. From the birth of the moon to the present, the moon has helped the earth resist the impact of many cosmic meteorites. Because of the gravitational pull of the Moon, the Moon affects the Earth's tides and plays a very important role in the marine ecosystem.

The Moon plays a very important role in reflecting the sun's rays and becoming a nocturnal animal at night.

I think so, because not only does the Moon bring us the light of the night, but the balance of forces in the Moon's movement also leads to the formation of tides on Earth, and if the Moon disappears, this balance will be immediately broken until a new balance is formed.

The disappearance of the moon will have a certain impact on the ecology of the earth, and people can intuitively feel that the night is darker in a lightless place, and it will not cause a devastating disaster.

If you destroy an asteroid with a nuclear bomb, you can destroy the moon with a nuclear bomb, in fact, this idea is a bit far-fetched.

The binding energy of the Earth is about 32 joules multiplied by 10, and the binding energy of the Moon's grip is about 29 joules multiplied by 10. Therefore, it is much more difficult to destroy the Earth than the Moon, requiring more than 1,800 times more energy.

On Mercury there is a place called the Calorie Basin, which is about 1,300 kilometers in diameter and is one of the hottest places in the solar system. The Calorie Basin came from a massive celestial impact that formed Mercury about 30 to 4 billion years ago when a large asteroid hit Mercury. Scientists speculate that this celestial body has a diameter of 100 kilometers and can produce 26 joules with an impact energy multiplied by 10.

And the energy of 26 joules multiplied by 10 is about the same as 1 billion hydrogen bombs, or we all concentrate the sun's light on the surface of the moon for 15 minutes. If this level of energy were capable of forming an impact crater with a diameter of 1,300 to 1,500 kilometers, it would also destroy the Moon. The diameter of the Moon is 3,400 kilometers, and if an asteroid with a diameter of 100 kilometers hits the Moon, then the material on the Moon will fall apart.

We can also study how to destroy the moon through the Loch limit. The Loch limit describes the value of the distance between the planet and the moon that causes the moon to be broken down by tidal forces, which was first solved by the French astronomer Loch, and eventually the moon will form a ring of debris around the planet. Scientists have discovered that if the Moon were 10,000 kilometers away from the Earth, closer than the current 380,000 kilometers, then the Moon would be shattered by tidal forces, forming a beautiful halo.

In the next few million years, Mars will see this happen, and Phobos will gradually get closer to Mars, reaching the Loch limit, and will eventually be crushed by the tidal forces of Mars. It turns out that if we destroy the moon, life on Earth will also suffer.
