Why does the temperature have no upper limit and can be raised infinitely, but there is a lower limit of absolute zero?

I believe that friends are no strangers to temperature. We are dealing with temperature every day and every moment. So how did this temperature come about? In fact, it also appeared with the occurrence of the Big Bang. Before the universe was born, space, time, temperature, etc. did not exist.

It was not until 13.8 billion years ago that a mysterious singularity had a big bang, time and space appeared, and temperature also appeared. The survival, evolution and development of life requires a suitable temperature. Only a suitable temperature can create a suitable living environment and can breed life.

It is with the light and heat from the sun and a suitable temperature for a planet of life like the earth that primitive life can be born, and millions of years of human beings can be born. In our cognition, the temperature mainly comes from the sun, and the radiation it emits every day comes to the earth, bringing us light and suitable temperature.

Before human beings entered the age of technology, we seldom thought about studying temperature, because in the eyes of many people, there is nothing to study about temperature, isn't it a very common thing. However, when human beings entered the era of technology, with the continuous development of technology, we gradually realized that temperature is not as simple as we think.

So what's so strange and mysterious about temperature? Scientists have begun to explore the temperature. Now we all know that the temperature can rise indefinitely, tens of thousands of degrees, tens of millions of degrees, and hundreds of millions of degrees can continue to rise. But what makes many people feel strange is that the temperature cannot drop indefinitely. It has a limit value, which is absolute zero, which is minus 273.15 degrees Celsius.

Here, many people may be confused: Why does the temperature have no upper limit, but a lower limit of absolute zero? In fact, it is not complicated to unravel this mystery. As long as we understand the nature of temperature, you may suddenly realize it.

What is the nature of temperature? According to the current research of scientists, the essence of temperature is the intensity of thermal motion of molecules. The more intense the thermal motion of molecules, the higher the temperature of the object, and vice versa. There seems to be no limit to the intensity of particle activity. To a certain extent, it can always increase the activity, so the temperature of an object composed of particles can be increased infinitely.

However, there is a limit to the weakened state of particle activity, that is, standing still. The movement of the particles is getting smaller and smaller, the temperature of the object will be lower and lower, and when it is completely stationary, the temperature of the object will be reduced to the lowest, and this temperature is absolute zero.

So can the temperature be lowered to absolute zero? According to current science it is not possible. Because the motion of particles can never come to a standstill, which is the same as the fact that the speed of light can never be reached. It is only a theoretical limit value, and it may not exist in the real universe. At least currently, with the scientific and technological strength of human beings, no matter how hard we try, we can only get a limit temperature close to absolute zero.

Perhaps many friends have seen this article and questioned whether there is an upper limit for the temperature. In fact, according to the current theoretical research of scientists, the upper limit of the temperature seems to exist, which is 140,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 million degrees Celsius. It is the Planck temperature, named after the German physicist Planck.

This temperature is so high that it is beyond our imagination. According to the theoretical research of scientists, it seems to be realized only once in the moment after the Big Bang, and it does not appear again later. That is to say, we cannot confirm the upper limit of this temperature. It is only a theoretical conjecture. Of course, even if this temperature has actually occurred, it is something we cannot imagine to raise the temperature to this level. possible.

Therefore, from a rational point of view, when we talk about the upper limit of temperature, we think that it does not exist. With the current scientific and technological strength of mankind, particle colliders have been able to create a high temperature of 500 million degrees Celsius, but this value is similar to the Planck temperature. than, is still a huge gulf. Relatively speaking, absolute zero is a theoretical limit temperature that we can approach infinitely, and the lowest temperature that humans can currently create is very close to absolute zero.

Whether it is the theoretical upper limit or the theoretical lower limit of temperature, they are still just a guess for us. Whether such a temperature exists in reality or in the universe, we still cannot be sure. Perhaps in some mysterious regions of the universe, there are temperatures beyond our imagination.

So what happens when the temperature reaches the upper or lower limit? Through the previous understanding, we have seen that the temperature originated from the Big Bang, that is to say, at the moment of the Big Bang, the temperature was the highest, reaching 140,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 million degrees Celsius. The temperature keeps dropping.

The upper temperature limit gave birth to the elements of the early universe and provided the basis for the universe's later evolution. And what about the absolute zero lower limit of temperature? By understanding the nature of temperature, we can see that if the temperature reaches absolute zero, the motion of particles will stop. And all things and the entire universe are composed of particles. When the particles are stationary, it also means that the entire universe will be in a state of absolute stillness.

This state is the end of the universe, and it represents the end of the universe. Perhaps the final end of the universe is like this, the entire space is completely static, and the temperature has reached its limit. If it is described in one word, it is the frozen universe. The upper limit of temperature creates everything in the universe, and the lower limit of temperature ends everything in the universe. This may be the fate of the birth of temperature.

Temperature is of great significance to human research and exploration of the mysteries of the universe, through which we can constantly uncover the truth of the universe. Even when human technology has developed to an extremely high stage, when we can create the Planck temperature, will we also create a universe?

If human beings can create a universe when technology develops to a certain extent, then we have to rethink the origin of this universe, is it really born and evolved naturally? Could there be a powerful and unknown super civilization behind it creating the universe and doing some experiment? Anything is possible until the truth is revealed.
