The discovery of a physical law makes scientists feel desperate, saying: I would rather not discover it

In the past half century, the pace of technological development of mankind has been astonishing. Compared with the current technological era 50 years ago, I believe that many older generations have a deep understanding of it. Even in today's post-80s generation, the backbone of today's society, if you look back carefully at the changes over the past few decades, you will be surprised at how rapidly human technology has developed.

In the past half century, why has the development of human beings in science and technology been so rapid? In fact, the main reason is accumulation. As we all know, the foundation of science and technology development is science, especially physics. Without the birth of many great basic theories of physics, I believe that there will be no rapid development of various science and technology. For example, Newton's classical physics sent rockets into space, Maxwell's electromagnetism led to the development of modern electrotechnology, Einstein's theory of relativity enabled the precise positioning of navigation satellites, and so on.

One hundred years ago, the emergence of these great basic physics theories laid the foundation for the rapid development of science and technology. Science and technology are always closely linked, and they influence and restrict each other. Without the emergence of basic physics, There will be no rapid development of science and technology, and the rapid development of science and technology will also accelerate the generation of new fundamental physics.

I believe everyone understands the importance of physics to human beings, especially when we start to explore the universe into space, we need the support of powerful physical forces. The development of physics is inseparable from various physical laws. The emergence of each physical law will greatly promote the development of human science and technology.

The new laws of physics are the forerunners of new physics and a precursor to the continuous emergence of new technologies. Some basic laws of physics can build a huge physical building and guide the development of science and technology. It is precisely because of the continuous contributions of previous generations in physics that the amazing scientific and technological achievements have finally been achieved in the past half century.

In the palace of physics, scientists have discovered many laws of physics, and they are very happy with the discovery of these laws, because they can promote the progress of human science and technology. However, the discovery of a law of physics has made scientists feel and claim: it is better not to discover, why is this?

This law of physics makes scientists feel desperate, and I believe many friends also know that this is the second law of thermodynamics, which is what scientists call the law of entropy increase. There are two laws of thermodynamics. The first law tells us that energy cannot be created out of thin air, it can only be transformed from one state to another, and that energy is conserved.

The discovery of the first law of thermodynamics ended some people's fantasy of creating a perpetual motion machine that can continuously output energy. This dream of perpetual motion machine is over, while others have proposed a new perpetual motion machine, they try to absorb energy from nature, and then drive the starter to continue to move outward, this dream does not violate the law of conservation of energy, That is the perpetual motion machine of the second kind.

So the second perpetual motion machine is achievable? Although it does not violate the second law of thermodynamics, it violates the second law of thermodynamics, the law of increase in entropy. According to the law of gain, the more energy used to do work, the lower the entropy, and the less energy used, the higher the entropy. In short, the higher the entropy of the waste left behind after energy is burned, the better.

For an isolated system, the smaller the useful energy, the larger the entropy. If we continuously absorb energy from nature and use it to continue to do work, then more and more useful energy will be produced, which obviously violates the law of entropy increase, thus proving that the second type of perpetual motion machine cannot be manufactured. .

The entropy increase method is used to describe the degree of confusion of the system. In an isolated system, the greater the entropy value, the greater the degree of confusion, and the entropy increase method is irreversible. From the date of birth of anything, the entropy value is As it increases, the system will become more and more chaotic, eventually leading to destruction.

For an isolated system, the entropy will always increase spontaneously, and the degree of order will become smaller and smaller. Such phenomena can be seen everywhere in our daily life, such as: the room will become more and more chaotic, the broken mirror will not recover spontaneously, the mixed liquid Cannot separate spontaneously, etc.

In a sense, the law of entropy increase is also the law of time. It tells us that time is always passing and cannot be reversed. This also tells us from the side that in the theory of relativity, the reverse of time is also impossible, and a time machine Only exists in science fiction, but not in the real world.

What really makes scientists hopeless about the entropy method is that, through it, the end of the universe is imminent, and that end is the heat of silence. If the universe is an isolated system, since the time of its birth, its entropy value has been increasing, the universe will become more and more chaotic, and eventually all energy is consumed, and the entire universe reaches a state of heat silence and stops functioning. , any life will disappear.

The existence of life will also accelerate the growth rate of the entropy value of the universe and accelerate the decline of the universe. This is because human beings and other life forms have negative entropy values. In order to maintain the function of life, energy must be continuously consumed. Therefore, the universe The entropy value of the system will also increase at an accelerated rate.

This is of course the case of the universe in solitude, what if the universe is not in solitude? I believe that many of my friends have already understood the multiverse theory, which is a speculation put forward by scientists that there is a wider space outside the universe, and there are countless universes.

If the multiverse theory is correct, our universe is not an isolated system, and useful energy can be continuously obtained from the outside of the universe. As long as the space outside the universe is not destroyed, our universe can also maintain a slowly increasing entropy value, continuously longer.

In any case, the discovery of the law of increasing entropy is indeed not good news. It tells us that the ultimate outcome of everything is destruction. No matter how powerful human technology is, human civilization cannot be sustainable. One day we will usher in The cataclysm, and the ever-developing technology of mankind, can only make the entire series of mankind go further by continuing the catastrophe.
