Are the knowledge points such as the hot movie "Lone Moon"?

The recently reflected "Lone Moon" tells the story of the maintenance worker Duguyue missed the evacuation notice due to an accident, and a person was left alone in the moon to live alone. Are the knowledge points about the moon mentioned in the film correct?

Where is the location of the Moon Shield Base?

Most of the place names used in the film are real on the moon, such as Guanghan Palace, Changzhu Lake, Rich Sea, and the Collins meteor pit.

The moon map has appeared on the screen many times, and the location of the Moon Shield Base is near the location of the first time human beings landing on the moon: the south of Jinghai. After the successful landing of Apollo 11th landing, Amsterram said in the ground communication, "This is the Jinghai Base", and this landing point is also named Jinghai Base.

There is also a famous attraction near the Moon Shield Base in the movie: the footprint left by human beings that represent "a small step, a big step for humans".

The "extended day" made by Duguyue

Can it be achieved?

In the film, Duguyue returned to the Moon Shield Base in order to obtain a hammer prototype of the universe and returned to the Moon Shield Base. Driving the solar moon cars all the way to chasing the sun to the west must be impressive. Because the moon has a rotation, the moon also has day and night.

The Jinghai Base where the Moon Shield Base is close to the moon equator. The average radius of the moon is about 1737.1 kilometers, and the rotating cycle is about 27.32 days, which means that after 27.32 days, it will be transferred to 360 degrees (that is, 2π arc). The speed of rotation at the lunar equator V = (2π × 1731.1)/(27.32 × 24) = 16.6 km/h, consider the rotation of the ground month system, which is slightly greater than the speed of the sun at the moon equatorial. Because the moon rotates from the west to east, the sun's direct point moves west. In theory, as long as you go west on the west on the moon day, you can get a longer sunlight, that is, the "extended day" made by Dugu Moon; if you can catch up with the movement speed of the direct sunlight point, you can be on the moon on the moon. Enjoy the eternal day, until the sun is blocked by the earth when the lunar eclipse occurs.

See stars on the moon?

The film does not highlight the starry sky on the moon, but on the night when the kangaroo "sleigh", the bright galaxy is pasted in the air like a huge oil painting. This is because the moon is not atmospheric, so the sky of the moon is black day and night, and the stars can be seen in theory; there is no sunlight at night, these stars will look more obvious, and they will not look like the earth like the earth Flash like that.

From the film that Dugu Moon has standing on the earth many times, we can find that the earth on the moon is also like the moon on the earth, with a change in the lack of cloudy. For example, when the first meteorite impact occurred, most of the earth was bright. When the people on the earth told Duguyue "you are not alone", the earth looked like a small cut. This phenomenon is well understood, because the earth is not glowing, and the bright part of the earth that can be seen on the moon is on the earth hemisphere of the earth, and the part that can't be seen in the darkness is on the night mid -ball.

Can "skiing" on the moon be realized?

The appearance and nature of the moon are different from the soil on the earth. They are mainly rock chips of basalt or oblique rocks, which are widely covered on the surface of the moon. Because they are directly exposed to various cosmic radiation, they are weathered by high -energy particles radiated in the universe, and the physical chemical properties and even isotope are different from sand and gravel on the earth.

The moon soil in the film is showing a dark dander -like debris, and there are many small stones. And thanks to the low -gravity environment, the moon soil on the surface will look more loose, which also makes the bridge section of "skiing" on the moon look more reasonable.

Can the "Hammer of the Universe" be created on the moon?

In the film, an asteroid named π chose to derail Mars and turn on track, and wanted to pierce the embrace of the earth. As a result, the monthly shield plan will be generated to use the moon's nitrogen 3 to create a new generation of weapons -the hammer of the universe. It will be launched towards the small planet π, crushed π to defend the earth.

一 -3 is a kind of homogenin of 种, and it is also an ideal nuclear gathering fuel. The nuclear reactor with 氦 -3 is very clean, without producing neutron radiation that is difficult to block, and the energy generated by the 氦-3 fusion reaction is 12.5 times the energy of the uranium-235 fission reaction. It is also scientific basis on the moon's 3 -3 on the moon. Because the moon has no magnetic field protection, the 氦 -3 in the solar wind can be directly injected into the moon surface, so a large number of 氦 -3 is stored in the moon soil. According to the estimated total amount of titanium iron ore on the moon, the total amount stored in minerals in the form of bubbles may be as high as 260,000 tons. If all are used for nuclear fusion, it can meet the global energy demand for 2600 years; and this and this can be met. It is just a huge amount of lunar-3 resources in the lunar world. Theoretically, it is easier to minimize. The total amount of 氦 -3 reserves on the moon is even much larger.

Du Guyue turned into a star ring guarding his blue star, like the dark and deep moon "accompanied" the blue earth. When Dugu Yue rushed to the asteroid π with the hammer of the universe, did you be moved by tears?
