Because all explosions are caused by positive feedback, Yong Duan is convinced that the Big Bang was also the result of positive feedback. Although we do not yet know the exact mechanism of this positive feedback, we can say that positive feedback created the universe.

There are many positive feedback in life, for example, the stock market booms suddenly and busts suddenly, stress concentration causes metal to break, a thousand miles of dikes to break because of the nest, the city effect, and so on. More importantly, positive feedback creates life.

3.1The essence of life

The mystery of life is a difficult problem that has troubled mankind for a long time. In fact, this problem is very easy. Living things are alive and have all sorts of magical functions because of their complex and orderly structure, and nothing else. All that soul stuff, all that living element, it's nonsense.

Many of the most important concepts we talk about are essentially refer to structures. For example, the nature of information is structure, the nature of time is structure, and the so-called "order" also refers to structure. By "ordered" we mean a structure that has some special function.

If we have the ability to change the structure of non-living things at will, including the position of every molecule and atom, then non-living things can live as long as they are properly designed. On the contrary, change the structure of the creature, and it may die immediately.

The reason why we can't bring non-living things to life now is because we don't have the ability to make very complex structures, the structures of living things are too complex. How complicated is it? Even the most advanced science and technology can't make a leaf of a tree. Complex structure will inevitably produce all kinds of magical functions.

The structure of living things is on the one hand very complex, on the other hand very ordered. Whether the structure is ordered depends on the function, if a system adds a new function due to the structure change, then it means that its degree of order has increased. The ordered structure comes from variation and natural selection. It might need 10,000 variations for an orderly structure to emerge.
