Human beings can produce 5.5 trillion degrees of high temperature, but can not reach absolute zero. Why?
Temperature is a magic concept. The temperature of the human body is generally maintained at about 37 ℃. If the temperature exceeds this, it means that the body has a fever, and you need to see a doctor in time. Whenever there is any change in the weather, we can intuitively feel the rise or fall of the temperature. Global warming has led to a sharp rise in the temperature all over the world. Everyone has a deep feeling. From the point of view of physics, temperature is the external expression of particle velocity, it is not the so-called macro sense of temperature.
Because of this, physicists can use accelerators to produce the highest temperature of 5.5 trillion degrees Celsius in history. This is a very terrible concept. We can’t bear 100 degree Celsius water vapor, let alone break the trillion degree temperature. The sun is recognized as the highest surface temperature on earth, reaching 6000 degrees Celsius. It is hard to imagine that the temperature created by human beings is even higher than that of the sun. If human beings can create such a high temperature, isn’t the whole earth melted by it? Human beings can produce 5.5 trillion degrees of high temperature, but can not reach absolute zero. Why?
What is the human understanding of temperature?
In fact, people’s understanding of temperature is one-sided. The faster the particle moves, the higher the temperature is. If it moves within a controllable range, when the temperature rises, it will not have a great impact on the surrounding things. The movement of particles is often limited by the speed of light. When it approaches the speed of light without limit, the energy will increase, and finally reach the temperature limit, which is the so-called absolute maximum temperature. Although human beings have made an obvious breakthrough in the production of high temperature, they have stagnated in the production of low temperature.
As we all know, 273.15 degrees below zero is called absolute zero. Since human beings can produce trillions of high temperature, why can’t low temperature? The principle is also related to the motion of particles. High speed motion will make the temperature rise. If the temperature drops, it means that the moving particles are in a static state. This is a very difficult thing. At present, human beings can not do it at all, because it is difficult to determine the position and momentum of particles.
Why can’t absolute zero be made?
A moving particle, no matter how slow it moves, will produce heat, so it is impossible to have absolute zero. Absolute zero can only be a kind of infinite approach, want to achieve is a luxury. It may be generally believed that it is easier to make high temperature than low temperature. In fact, the principle of the two is similar. High temperature keeps breaking through, but it can never reach the highest temperature, because the value is difficult to calculate by human beings.
There is no absolutely static material in the world, so it is impossible for human beings to produce absolute zero degree, which can only be infinitely close. Whether it produces high temperature or low temperature, it has a high similarity with the speed of light. The speed of light is regarded as the fastest speed in the universe. The expansion speed of the universe is faster than the speed of light. It is expanding constantly. No matter how to catch up with the speed of light, it will never catch up with its expansion speed. Theoretically speaking, there is no limit to speed, just like high temperature and low temperature. What do you think of this? You can leave a message for interaction.
