Mysterious glass ball
Chinese scientists discover glass balls on the moon! Could it be that aliens accidentally got hot here when they left the solar system? To unlock this secret, we must first know, how did the glass ball form? The Chang'e-4 probe is the first human probe to land on the far side of the moon, launched on December 8, 2018, and implemented a soft landing on the far side of the moon in January 2019.
Chang'e 4
Chang'e-4 carried the Yutu-2 lunar rover at the time of launch, and with the separation of Yutu-2, it began to patrol the far side of the moon, after all, humans do not know so much about the far side of the moon. Scientists have long believed that the formation of the moon is inseparable from the earth.
In fact, in the early days, the United States has discovered that there is a large amount of glass material on the surface of the moon, and later after bringing this material to the earth, it was found that these materials on the surface of the moon are similar to those on the earth, and the content of the elements inside it is higher than that of the earth, which triggers the theory of the formation of earth-moon objects due to the impact of the earth and the moon.
Lunar impact craters
At night, if you take an astronomical telescope to observe the moon, you will find that there are countless craters on the surface of the moon, as well as impact craters, which means that in ancient times, the moon has suffered countless impacts, and its impact scale and strength are so large, but the question that follows is that these impact craters on the surface of the moon do not seem to have much to do with the earth. For more clues, we need more experimental data.
This is also the reason why Yutu-2 has been observing the far side of the moon, because in the early days, the United States brought back a large amount of lunar soil from the moon, and they studied these lunar soils thoroughly and did not find anything of value. But the far side of the moon is different because no probe has been there before, and no one knows what the lunar soil there contains.
History of the Moon
Some friends may not believe that it is possible to know the history of the moon with only this dirt? Then our discovery this time, the discovery of glass balls on the surface of the moon is not the first time for human beings, before this the United States also thought that these glass balls are not left by aliens, but pure natural formation, but this formation process and the environmental conditions of formation, are extremely complex.
Scientists have said that to form glass on the lunar surface, it requires extremely high temperatures, at least thousands of degrees, before the material can be formed after rapid cooling. Space is extremely cold, with an average temperature of more than 200 degrees below zero, and there is no chance that the lunar temperature will suddenly reach thousands of degrees Celsius, and the only way is to impact.
Theia hit
A violent impact can make the temperature of the local area as high as several thousand degrees Celsius, and then after rapid cooling to form glass beads. Before this, scientists had done a simulation, using a planet called Theia, hitting the pristine earth, and then under this huge impact, the earth and Theia were completely crushed, turning into a large number of material clusters, and the mass of the material mass where the earth was located was large, so under the action of gravity, the earth swallowed a large amount of material, and the moon also originated in another mass of material.
In the time after the impact, the Earth and the Moon formed successively, and then began to enter the cooling stage, a large amount of heavy metal material sinks into the core, forming the core of the Earth and the lunar core, and then the lighter material condenses on the surface to form the surface of the planet. During the cooling process of the Moon, its surface contains a large amount of glass material.
Article summary
The countless impact craters on the lunar surface indicate that there have been countless impacts in the next stage, and at this huge impact frequency, these materials are rapidly forming glass balls under the action of high temperature and high pressure. So, these glass balls are not left over from aliens, but important physical evidence that bears witness to the early history of the moon. Through them, scientists were able to determine some of the early moon's conditions earlier, so where do you think these glass balls came from?
