Why is it that the moon is bright on the earth, but it is dark on the moon, and there is no light?

Because the moon is able to reflect the sun's rays and is itself black, the moon is bright when viewed on the earth, but it is black and there is no light on the moon.

The reason why the moon appears bright is because the sun's rays shine on the moon. The moon was illuminated, and the surface of the moon was actually completely black.

Without the moon, the Earth would have changed in the following ways:

1. The tide will disappear. Due to the gravitational forces of the sun and the moon, the lithosphere, hydrosphere and atmosphere of the earth.

The periodic movements and changes of the middle and tidal generations are collectively referred to as tides.

Once the moon disappears, the tide will not exist, and the living habits of marine life will change significantly, even leading to the extinction of some species, and our port engineering, shipping traffic, fishing and salt industry, and coastal environment will be affected.

2. The disappearance of the moon will affect the vertical intersection angle next to the yellow red wheel.

This in turn affects the rotation of the Earth.

The Sun and Moon often exert gravitational pull on the equatorial uplift beyond the equatorial plane. The difference in gravity becomes a moment that brings the earth's axis closer to the yellow axis and the celestial pole closer to the yellow pole.

If there is no bright light before the month, the earth will change in the following ways:

Solar and lunar eclipses: The moon is the only celestial body observed on Earth, and its periodic movement brings natural phenomena such as solar and lunar eclipses. Without the moon, these astronomical phenomena would not be overshadowed.

Earth's rotation speed: The Earth's rotation is gradually slowed down by the Moon's gravitational pull, which slows down by about a second in a month. Without the influence of the Moon, the Earth would probably rotate faster, resulting in shorter daylight hours and longer night hours.

Tides: The gravitational pull of the moon also has an effect on the macro-digging tides on Earth. In the absence of the moon, the tides on Earth would be very faint, perhaps with only a few tiny ups and downs.

Biological evolution: The presence of the moon has also had an impact on the evolution of organisms on Earth. For example, the cycle of the moon with respect to the earth is days, which has an important role in the reproduction, hatching, etc. of the animal.

Without the influence of the Moon, life on Earth would have exhibited different evolutionary paths and ecosystems.

In short, the absence of the moon will make the earth's natural environment, climate and meteorology, ecosystem and other aspects of the great changes, but the specific degree and method of change still need more scientific research.

The reason for this situation is due to the following factors.

First, neither the earth nor the moon can emit light on its own, it needs to be refracted under the illumination of the sun, and the reason why the moon can be seen on the earth is because the moon happens to be illuminated by the sun, and the side that shines can be seen by people on the earth, but if the earth and the moon happen to be on a flat line, there will be a solar eclipse.

At that time, the moon will be between the earth and the sun, because it blocks the sun's rays, so it is obviously in front of the earth, but the moon is not visible, in fact, even if there is a lunar eclipse.

The side facing the sun is also very bright.

Second, there is no atmosphere on the moon.

Either extremely cold weather or extremely hot weather, astronauts generally choose the far side of the moon.

Landing, which is a better way to ensure safety, and the far side of the moon does not receive sunlight.

The line refracts, and naturally looks pitch black. And because there is no atmosphere, the moon's ability to refract light is far less than that of the earth, and the diameter of the earth is much larger than that of the moon, which brings a stronger sense of vision, so the earth is very bright on the moon, like a blue planet.

Thirdly, at the time of the lunar eclipse, the Earth is between the Sun and the Moon, in this case, the sun does not shine on the Moon, and the entire Moon is in a state of darkness, in this case, there is no light on the Moon at all. In normal times, when you see a full moon or a waning moon, it is affected by the earth, and there will be a full moon when there is no earth occlusion, and a waning moon when it is partially occluded.

Fourth, on the surface of the moon, there is no difference from an absolute vacuum, which also reduces the ability of the moon to refract the sun's rays, so most of the lunar rays we see are reflected vertically, and because of this, the moon's rays are not strong, otherwise it is likely to cause some abnormal natural disasters.

Because the moon emits light because it is refracted by other rays, the moon itself does not emit light, so standing on the moon and looking at the moon is black.

Because the moon itself cannot emit light, it will reflect light with the help of other objects.

<> in the universe, there are many phenomena that we humans cannot explain, so we human beings have been exploring the mysteries of the universe, from ancient times to the present, have never given up the curiosity of the universe, but with the continuous exploration of the universe over the years, and many previously unexplained phenomena, now there is a clear answer, this people used to say that why the moon is shining on the earth? The reason why people wonder about this question is that after people's exploration, the moon itself does not actually shine, but we can clearly see that the moon will shine brightly on the earth.

The reason why we see the moon shining on the earth is because the sun's light shines on the moon, and the moon refracts the sun's light to the earth through itself, so the moon we see on the earth naturally shines, although the moon refracts the sun's light to the earth, the light has become a little weak, but our human eyes are more sensitive to light, even in the daytime, we can still see the white moon, and at night, the moon's light is even more dazzling.

Of course, the moonlight we see under normal circumstances is bright white, but there will be some special circumstances, resulting in the light refracted by the moon is not white, but red or orange, which is due to the existence of the earth's atmosphere, and the moon orbits in a certain orbit, which will only refract different light. There is another important reason why we can see the moon shining on the earth, that is, the distance between the moon and the earth is very close compared to other planets, in the solar system, there are eight planets, and other planets also revolve around the sun like the earth, but we feel on the earth that it is difficult to see the light they emit, which is naturally due to the distance between them and the earth, and the orbits are different, even if they can be observed, it is only a short time.

Because the moon is able to reflect the sun's light, and the light of the surrounding stars is very weak, the moon is seen to be bright.

The moon has no color, and the soil on the moon can reflect the sun's rays, so the moon we see is bright.

Because the sun's rays will shine on the moon, and then the moon will reflect this situation, which will also allow us to see the moon in different shapes.

Because the sun's rays will hit the moon directly, the moon will be reflected, and then we can see the light on the moon.

This is because the Moon not only absorbs sunlight but also reflects it, so it looks bright.

This is because the distance between the Moon and the Moon is relatively long, so the visibility is relatively low, and the position of the Moon is not clear at all.

Because the moon itself does not emit light, it is by refracting the sun's rays that people who stay on the earth can make it appear that the moon is shining, and they can go to the moon and find that the moon is black.

The earth and the moon itself do not emit light, only by reflecting the sun's light can we see, looking at the moon on the earth, the moon emits a cool light, but if you look at the earth on the moon, then the light emitted by the earth is blue, the earth looks like a sapphire, extremely beautiful and moving. Since the Earth is larger than the Moon, about twice the diameter of the Moon, and the reflectivity is 4 times that of the Moon, the Earth is larger when viewed from the Moon than the Moon seen from the Earth, and it is 80 times brighter than the Moon.

Because the Moon reflects the sun's rays, the Moon is bright when viewed on Earth, while the Moon itself does not emit light, so it is dark on the Moon. Because the moon itself does not emit light.

Within the scope of the eight planets of the solar system, light can be said to be everywhere, because the sunlight continuously emits light and heat. However, light can only be seen clearly with the human eye if it has a rotating effect with chemicals, causing a meager force and sending conditions. It's not that there is no light in the vacuum pump, but because the vacuum lacks the chemical substance that has the effect of light, and there is no reflection of light into people's eyes, and the sky you see is of course black.

On the earth, due to the presence of air, the atmosphere is divided into several layers due to the heating of light, and also due to the molecular structure of vapor in the air and the action of light, which produces scattering and other effects, O2 Harachiko has a strong dispersion effect on dark blue light, so the sky you see is blue. The direction of the geomagnetic field can deflect the velocity direction of the free electrons, and the free electrons and some chemicals in the air can also have an effect on the free electrons in the solar storm, and some light phenomena can also occur, such as meteors.

There is no air in the moon, and there is no dispersion effect of the molecular structure of the vapor on light, so the moon you see is black, but if you stare at the sky, there are stars, the sky is black in Chang'e-4 and other detection images, the fundamental reason is that the key focus of the road surface is the road surface, and the positive reflection of the road surface covers the weak night sky. , you will also get a more expansive image of the universe than in space, after all, the moon has no atmosphere to block it.

The lunar land shot by the rover is also very bright on the moon. In fact, on the moon, because the light is not isolated by air, the ultraviolet sterilization lamp in the light is more intense, and it has a higher melting point effect after irradiating the object, which promotes the maximum temperature of the detection instrument layer to reach about 180, which is also the main reason why the working time of China's Chang'e-4 lunar rover will bypass the moon at noon The moon has no air, and the strong light at noon is several times more obvious than that on the earth.

The reason why the moon can shine is because the direct sunlight causes the ignition of the moon, not the moon itself, and the rotational movement and rotation movement between the earth, the moon and the sun ensure that the earth can become vibrant.

The Moon rotated as fast as the Earth billions of years ago, and if you look at the Moon then, you will see the rest of the Moon. However, due to the close proximity of the moon to the earth, the strong gravitational pull of the earth slowly pulled the rotation of the moon to a halt, until now the rotation of the moon has been completely stopped by the earth, so the moon only faces the earth, this phenomenon is called tidal lock. It is worth noting that the Moon still theoretically rotates, except that the rotation and the time of orbit around the Earth are the same as 29 and a half days, but the Moon still sometimes oscillates a little, and we can see a total of 59% of the lunar surface.

Moreover, the tidal action of the moon also slows down the rotation of the earth, 200 million years ago, the earth's rotation took only 22 hours, and today it becomes 24 hours and feast, and the rotation of the earth relative to the moon will stop in billions of years. Some scientists have calculated that there will be 47 hours in a day, and only a few places will see the moon in Naling.

Because the Earth is not a bright moon of the moon.

Because the moon is facing the earth head-on when it revolves around the earth.

The tides are locked, and the moon is always facing the sun on one side.

Because the speed of the Moon's rotation is the same as the speed of the Moon's revolution, use your mobile device to add a new annotation or categorical annotation: ?id=

The Moon does not have a front and back, and you can only see one side of the Moon due to the close rotation speed of the Earth's Moon.

The best answer is false, the gravitational pull of the Earth and the Moon does not cause any acceleration in the tangential direction of the Moon's rotation. The Moon always faces the Earth on the same side, and the mathematical explanation is that the rotational speed = the rotational speed. But why is it so coincidental that the rotation speed is equal to the revolution speed?

Science can't explain it at the moment. In addition, the radius of the Sun is about 400 times that of the Moon, and the distance between the Earth and the Moon is exactly 400 times the distance between the Earth and the Moon, so the Sun and the Moon are the same size when viewed from the Earth. Many unnatural coincidences raise suspicions that the Moon is a man-made celestial body, not a natural formation.
