A planet that will rain “diamond rain”

  On a certain day of a certain month, the sky was gloomy, the sky was covered with dark clouds, the thunder roared in the distance, and a violent storm was approaching. Suddenly, a bolt of lightning pierced the sky, the sound of huge thunder was deafening, and the wind was violent, and heavy raindrops fell all over the sky. Please close your eyes and listen first, how can the rain drop on the ground make such a loud noise? Then, please open your eyes. Why are the raindrops appearing in front of your eyes so dazzling, the heaven and the earth are illuminated by their rays of color? It turns out that this is a shining “diamond rain”!
  What an exciting moment, what a desirable scene! I believe everyone wants to be on the scene and have close contact with the dear diamond. However, scientists tell us that it is impossible to see “Diamond Rain” on the earth! However, on Jupiter and Saturn, “diamond rain” is the most commonplace. What is even more exciting is that on these two planets, the “rainfall” of the “diamond rain” is huge. As far as Saturn is concerned, the annual “rainfall” can reach thousands of tons, and many single diamond “raindrops” The diameter is even more than 1 cm.
  Saturn and Jupiter are gas giants, their diameters are about 120,000 kilometers and 140,000 kilometers, respectively. The main gas on the two planets is hydrogen, and they both have an atmosphere at least tens of thousands of kilometers thick. Among them, the outermost atmosphere is involved in creating the “diamond rain”. In this atmosphere, there is no more than 0.5% methane, which is the raw material for “diamond rain”. Of course, methane alone is not enough. The formation of “diamond rain” is indispensable to another important “heritor”. It is the strong lightning on the two planets. It is said that this lightning is 100 times stronger than the lightning on the earth. .
  Under the action of strong lightning, methane was broken down by electric current and instantly turned into carbon black. In the process of declining, carbon black turned into graphite due to the increase of air pressure. The graphite continued to descend all the way until it dropped about 6,400 kilometers. Under the increasing pressure, the graphite finally transformed into a gorgeous, shining diamond. We might as well imagine how intoxicating this “diamond rain” scene should be! However, the beautiful and spectacular “Diamond Rain” will not stop falling rapidly because of its beauty. After falling by about 30,000 kilometers, they finally paid the price for themselves like moths to the fire. Under the joint destruction of extremely high pressure and temperature, a heart-pounding diamond rain finally turned into A vast ocean of liquid carbon. The “Diamond Rain” ended its dazzling journey in a flash. Of course, this does not mean the end, because a new round of “Diamond Rain” is already in the making.
