What's the point of scientists creating the coldest known substance?

In their laboratories, scientists in the United States and Japan have cooled the ytterbium atom to one billionth degree Celsius higher than absolute zero, which is lower than the assumed temperature of the deepest part of the universe and all atoms stop moving. Scientists use lasers to limit the motion of 300,000 atoms in an optical lattice. The cold matter they created is colder than the Dart Nebula, the coldest known space region. The temperature of the Dart Nebula is about 1 Kelvin, which is minus 272 degrees Celsius, only higher than absolute zero 1 degrees Celsius. In the latest experiment, the temperature of ytterbium atom is lower than that of darts nebula.

Rice University scientist Caden? Hazard said that the result of cooling to this extremely low temperature is a real transformation from physics to quantum mechanics. By studying and understanding them, we hope to discover new physical phenomena. The temperature of molecular motion is intrinsic. The faster a molecule moves, the more intense its collision and the higher the heat it generates once it moves. On the contrary, if the molecular motion is static, the less heat generated during collision, the lower the heat generated. As the temperature decreases, the molecules reach the lowest temperature in the universe when they are at rest. Once a person enters such a harsh environment, he is likely to become a patient and freeze to death in a short time, making it impossible to survive.

The lowest temperature on the earth has reached 94.5 degrees Celsius, but this is the lowest temperature on the earth, not the lowest temperature in the universe. Scientists found through relevant calculations that scientists also gave a positive answer, which is obviously impossible. With the current technology of human beings, it is quite difficult to make something infinitely close to absolute zero if you want to make absolutely static matter. As far as scientists know, ABS is a kind of heat insulation material. Because of its special manufacturing process, ABS is the only material with the best thermal insulation performance in the world. In order to achieve real mass production, human beings are still working hard with existing technology.
