Why can't humans create "absolute zero", and the universe may become meaningless?

For people, because of the presence of tactile nerves, we can be said to be very sensitive to temperature. If it is a little hotter, it may make us feel a little overwhelmed. Generally speaking, it will make us feel very hot if it exceeds 30℃, and once it can exceed 37.5℃ of people's body temperature, it will cause a high fever.

However, it is important to understand that in nature and even in the universe, this temperature can be said to be extremely insignificant, or even negligible. For example, the temperature of the surface of the sun can be at least 5000°C. There is a definition in physics, that is absolute zero, so how scary is it once absolute zero is created by people? At that time, the universe may be gone.

Everyone knows that the calorific value of sunlight comes from the internal chemical substances that are constantly producing nuclear fusion reactions. The temperature of its surface can reach 5000 ° C, which means that basically all chemical substances are close to the surface of the sun. It melts and even fades in an instant.

However, for experts, it has long been possible to create a temperature of hundreds of millions of degrees Celsius in the laboratory, but there is also a lower limit of temperature in the universe, which is absolute zero.

Regarding absolute zero, at present, experts have not been able to create it, nor have they discovered it in the universe, so what does it represent?

First of all, let's understand that temperature is mainly a physical index value that considers the heat and cold conditions of an object, and it is divided because of the violent level of molecular fitness.

This is because the molecules need mechanical energy in the case of fitness exercise, and the violent level of irregular fitness exercise will continue to increase in the future, and the collision between the molecules will cause heat generation. Therefore, if the molecules have no way to obtain kinetic energy, the temperature will also decrease.

Absolute zero is equivalent to -273.15°C on the sign, which is also the minimum temperature among hot blood.

This definition was first clearly put forward by the scientist Sbury Bartley Kelvin, and thermal science also used his name to define the temperature scale enterprise, and absolute zero was also defined as the gradual change of the temperature scale, which is Kelvin!

The calorific value in the sunlight enters the earth mainly according to the radiation source. When a part of the solar radiation enters the earth, the light quantum collides with the molecules of the earth's core. At this time It causes the molecule to obtain mechanical energy.

For the earth, basically everything can be shrouded in the radiation source of sunlight, so this kind of heat can be continuously obtained for the earth.

Natural light imparts accelerated kinetic energy to the molecules, so it is said that the irregular fitness movement among the molecules on the earth is aggravated, which in turn causes this kind of heat generation on the earth.

As everyone knows, the temperature in the universe is extremely low. This is because although sunlight can transmit such radiation sources like other stars, it is necessary to understand that the stars far away from it get very little radiation sources. The temperature is also lower.

The research of biologists has shown that the temperature of the indoor space between the stars and the sun can be as low as minus 272 degrees Celsius, which is basically close to absolute 0 degrees.

In fact, this is mainly because the cosmic indoor space is close to the vacuum pump, and there are no molecules and particles, so the radiation source of sunlight cannot make subversive innovations for them, thus causing the temperature in the cosmic indoor space to be relatively low.

Why can't people create absolute zero?

To understand that if absolute zero is created, it means that the molecular particles will stop fitness, and this is impossible to guarantee.

On the other hand, for the global and indoor space where molecules and atoms are located, everyone has not yet been able to manipulate some of their transformations, so experts have no way to successfully create absolute zero.

In ancient history, biologists previously reduced the temperature to 0.71 Kelvin in 1926, and then in 1933, biologists broke the record and dropped it to 0.27 Kelvin.

As everyone knows, this is not the least situation. By 1957, it also set a low temperature record of 0.00002 Kelvin.

Although the temperature is already extremely low at this time, although it is infinite absolute zero, there is no way to do it.

In order to achieve absolute zero, all molecular fitness activities must be terminated. However, it is impossible to understand that molecular fitness activities are unlikely to be terminated, so there is no way to complete them. What's more, if the absolute 0 degree happens, it is very likely that the universe will disappear at that time.

This is also because the universe came into being because of an explosion at the starting point 13.8 billion light years ago, and the current universe is still expanding, but the expansion rate is very slow.

And this kind of molecular fitness movement is the mechanical energy of the continuous expansion of the universe, but at present, biologists have not figured out what the source of this kinetic energy is.

If the universe can reach absolute zero, then it is very likely that the end of the development trend of the universe is likely to come, so it is impossible for people to hit absolute zero at all, and it is even less likely to go up and down the development trend of the universe.

Now that this experiment is being carried out, it is likely that many biologists are still trying to get rid of the previous record. But after we study the nature of some things, we will find that there is no way to change the inevitable trend of their development.
