Water is the most common substance on the earth, and depending on the temperature, water can have three forms: gaseous, liquid and solid. For example, water vapor is the vaporization of water. After the water solidifies, ice is formed. However, ice also has many different states. Scientists have discovered a special substance called No. 7 ice. So what is No. 7 ice? Some people say that this material freezes faster than sound. If it is thrown into the ocean, it can even freeze all the oceans on Earth? With these questions, we might as well come to understand the relevant knowledge.

No. 7 ice is a very special substance. Although it exists on the earth, humans cannot make this special substance because its production conditions are very harsh, and it must be in an environment of 4.9 degrees Celsius. At the same time, it also needs to generate an external environment of 10,000 times the atmospheric pressure. The two work together to produce No. 7 ice. Because the environmental requirements for both are too strict at the same time, it is impossible to make No. 7 ice by artificial means. At present, this material mainly exists in the mantle from 410 kilometers to 660 kilometers away from the surface. Humans also accidentally discovered No. 7 ice in diamonds.

So, can this substance really turn the earth into an ice city in an instant? Since No. 7 ice is not easy to prepare, scientists don’t know much about this substance. They only know that the extension speed of No. 7 ice can reach 1,600 kilometers per hour. A small piece of No. 7 ice can completely freeze the ocean in a short period of time. This sounds incredible, but the special properties of No. 7 ice can indeed achieve this, so No. 7 ice is very important for humans. Dangerous, after all, no one wants to go back to the ice age.
Although it is difficult for humans to produce ice 7 on their own, it is not ruled out that ice 7 will be produced under special circumstances. For example, when an asteroid hits the earth, it will generate huge pressure instantly. If the temperature is right, it is very likely to be produced. No. 7 ice, and if the asteroid falls into the ocean again, it is absolutely devastating for the creatures on the earth.It can even be boldly guessed that the reason why the dinosaurs went extinct on the earth back then may have been caused by this reason, so the hazard of No. 7 ice can never be underestimated.

. Fortunately, the earth on which humans live is in a safer space. The possibility of an asteroid hitting the earth is very low. It has only happened in billions of years. There have been several relatively large-scale meteorite impact events, and now humans have very advanced observation methods. Before the asteroid approaches, human detectors can find the target and accurately monitor its trajectory. Once found It poses a threat to the earth, and it can also be destroyed or diverted by launching spacecraft in a targeted manner, thereby reducing the danger.
Judging from the discovery of No. 7 ice, humans’ understanding of water is still very limited. Since there is No. 7 ice, is it possible that there are other materials with similar physical properties? A brand-new energy source to solve the energy crisis currently encountered by mankind. At the same time, relying on the research on ice No. 7 can undoubtedly play a positive role in exploring space. After all, there are still many gas planets in space or the temperature is too high. It is difficult for humans to set foot on the planets, but it is not impossible to use ice No. 7 to freeze or cool these planets so as to facilitate human exploration. All in all, although No. 7 ice is objectively dangerous, as long as it is properly grasped, it may be able to play a huge role.
