Does absolute zero really exist? How scary is absolute zero? I believe everyone has heard of absolute zero, but whether it really exists has always been a mystery. Let’s find out together.
Some terms in physics are completely different from what we understand literally. For example, we have learned about some concepts in temperature. Most people think that what we call absolute zero is zero degrees in a state, but it is not at all. Absolute zero, if we use the degrees Celsius we are exposed to daily, is minus 273 degrees Celsius. The lowest temperature that we humans can come into contact with is only minus 60 to 70 degrees Celsius, and at absolute zero, all thermal motion will stop.
 And as we all know, in the winter, the body's metabolism will slow down, which is related to temperature. Therefore, whether minus 273 degrees Celsius actually exists has always been a question for scientists. Until now, technological development has reached a certain level, but the exploration of absolute zero is still in a skeptical stage. However, people still have unified research and results on the existence of living things below absolute zero and the existence of matter in nature. You must know that each substance is composed of molecules, so the atoms existing in the molecules are moving infinitely. But when atoms are at absolute zero, they will definitely stand still and not move.
Therefore, light, which travels the fastest in the world, will never be spared under absolute zero. Why light can be seen, this shows that light is also composed of small particles. Thunder first sees lightning, but at absolute zero, even the fastest-propagating light will definitely turn into an honest photon and stay put. Today, the real existence of absolute zero and the research results on absolute zero are actually divided into two groups. One group believes that the real existence is only in places that we cannot see, and the other group believes that absolute zero is just something in our ideal state.
