Tengjia came to worship for nine days.

The news went to the eighteenth floor of the underworld.

On May 23, 1985, a Greek scholar was debugging his 11-centimeter refracting telescope. At that time, the age of the moon was 4, that is, from the New Moon, roughly only 4 days had passed. Among the 7 photos of the moon ** taken in a row, there is one that attracts everyone's attention, and there is a clear bright spot that was not expected in advance.

After verification, the highlight is located in the area of Proclus C crater, near the moon's light-dark line.

In this regard, the Greek scholar put forward a bold hypothesis. He argues that since the moon has no atmosphere, the temperature of the part of the moon illuminated by the sun is very different from that of the part that is not illuminated by the sun.

When the sun rises from a certain part of the lunar surface, that is, from those areas that are just near the line between light and dark, the temperature of the lunar surface suddenly changes from night to day, from more than minus 100 degrees Celsius to more than 100 degrees Celsius. The intense and rapid temperature change caused the moon rock to expand and crack, and the gas enclosed under the rock suddenly rushed to the lunar surface and expanded rapidly, producing a bright and brief luminescence.

Recently, a communications engineer in the United States made a similar view. He has examined some lunar rock specimens collected from the moon and found that the rocks contain volatile gases like helium and argon. He believes that the electron energy released when the moon rock thermally ruptures has the potential to ignite the volatile gases and cause a brief flash of light.

He also said that his assumptions were not unfounded, and that it was said that moon rocks did spark when they were artificially fractured in a laboratory on the ground.

It is true that many times in the past, such transient luminescence phenomena have been found near the moon's line between light and dark. However, this sparkle has also been observed in the dark parts of the Moon, where sunlight is not available. How can this be explained?

Hello, glad to answer for you.

The biggest feature of knowing is that it is perfectly combined with the search engine, so that the hidden high-volume laughing knowledge owned by Qi Hanhu is transformed into explicit knowledge, and the user is not only the user who knows the content, but also the creator of knowing, and the knowledge data accumulated here can be reflected in the search results. Through the interaction between users and search engines, the community of search engines is realized.

Knowing can also be seen as a supplement to the function of the search engine, so that the tacit knowledge in the user's mind becomes explicit knowledge, and through the precipitation and organization of the formation of a new information base, in which the information can be further retrieved and used by the user. This means that the user is both the user and the creator of the search engine. Knowing can be said to be a humanized refinement of search engines that rely too much on technology.

Hope it helps, hope, thank you.

What you don't know, others know, and when they tell you, you know.
