The giant moon cave discovered in Japan can hold 1 1 10,000 people. Will the moon be the first choice for immigrants?

There are many volcanoes on the earth because the lava below the earth's crust is active. But there are no volcanoes on the moon, because most of the lava inside the moon has cooled down, and the core lava can't penetrate the surface of the moon, so the moon looks very cold, and there is no volcanic eruption or lava flowing out on the surface. However, Japanese astronomers discovered the secrets of the early moon by observing the lava tube on the surface of the moon through the lunar probe. What the hell is going on here?

In September 2007, Japan launched the Chang 'e probe to the moon. It can scan and image the surface of the moon in detail, and can also simply detect the internal structure of the moon. After orbiting the moon for two years, the probe landed on the surface of the moon. ? However, in the past two years, the detector has also collected a lot of data and sent it back to Earth. Earth-related researchers found a 50-kilometer-long hole on the moon after analyzing the images and data returned by the detector. ?

This hole is close to an ancient volcanic area on the surface of the moon called "Marius Mountain". This hole is about 65m in diameter, and scientists call it the "moon skylight". 50m below the entrance of the cave is connected with an almost vertical transverse cave, which extends downwards and has a curved side, and the internal space is very large. The data shows that it extends nearly 50 kilometers, and the analysis shows that there may be relatively thin air inside.

How did this huge cave, which is as long as 100 mile, form? Astronomers believe that this is a medium-sized hollow lava tube, which was formed by gas eruption in the early lava state of the moon about 3.5 billion years ago. According to the mass and volume of the moon, the maximum diameter of this medium hollow lava tube can reach 5 kilometers. If it is really so big, human beings can build a city in such a big cave by immigrating to the moon. As long as the hole is sealed with glass, a large three-dimensional underground city can be built below. As long as there is water and air circulation similar to the composition of the earth's atmosphere, such caves can accommodate 6,543,800 people. ?

After Japanese scientists discovered huge holes on the moon, some astronomers also found as many as 200 "skylights" near the equator of the moon through other detectors. ?

After the Japanese discovered the huge caves on the moon, they planned to land humans on the moon in 2025. They are worried that this huge cave or becoming a base for major space-faring countries to land on the moon will become the object of debate. Junichi haruyama, a scientist at JAXA Institute of Space Science, said: "The harsh environment on the surface of the moon is not a place for human beings to stay. No one has set foot on the moon since Apollo landed on the moon. " ? However, the discovery of underground caves on the moon will rekindle people's hopes of landing on the moon. ? "They also expected to use this hole to build a lunar base, but this plan was later abandoned due to the huge cost.
