What is life? Is the human definition of life subjective or objective?

Life, if at a shallow level, is the period from birth to death. At a deep level, it is your only and forever unrepeatable memorial. Of course, this remembrance will be permanent, because life is yours and no one else can take it away.

But I don't think it's scary to die, because you're no longer afraid of death, so you're lucky.

Life is objective, but the human definition of life is subjective. It's as if a tree exists objectively, but we humans define what a tree is, and that's subjective.

My definition of life is as follows: all life in the universe is a kind of energy, which first has independent perception and independent perceptual consciousness, and then more advanced life forms have thinking and logical consciousness. Secondly, the existence forms of life are numerous and numerous, and according to the environment and space in which they live (i.e., from 1-12 density or 0-20 dimensions), they can be roughly divided into monoplasm, multiple, material, energy, and etheric bodies.

Its lifespan ranges from one to as small as life and death with the snap of a finger, and as large as one with the universe without life and death. (Note; In fact, time does not exist in the real universe).

The definition of life is: to reproduce for the purpose of spontaneityEntropy changefor the process of evolution and adaptation in specific ways.

Of course, life forms want to reduce their entropy.

But this is not always successful: sometimes because of the disruption of homeostasis, such as aging; Sometimes it is because it is not able to completely resist the high entropy pressure of the outside world. Entropy change should be mainly oriented to metabolism and the processes that regulate metabolism: material, energy, information.

Everything is life, that is, the process, and the process basically has three stages: occurrence, survival, and extinction, and its basic characteristics are: the immortality of matter (nuclear reaction.

Except that, in fact this is also in accordance with Gödel's theorem, but the structure of matter changes (at what stage), so the so-called life (what we care about) is logically the structure of matter.

Basic Attributes of Life:

Self-regulation is an essential attribute of life. At every moment of its existence, any life is constantly adjusting its internal functions and adjusting its relationship with the external environment. The self-regulation of higher organisms is multi-layered, including molecular, cellular, and holistic regulation.

Even prokaryotes.

There is also self-regulation, and it is also achieved through a variety of pathways. For example, bacteria have the ability to synthesize many molecules they need, and whether a molecule is synthesized and how quickly it is synthesized varies depending on its internal state and environment.

Life is a process of interaction between heaven and earth. Heaven and earth interact, one yin and one yang; Back and forth. The yang is moving, so the loss is the living, and the loss is not lost, that is, death.

The yin is a quiet brigade, so it is Zheng Huaisheng who can get it, and if he can't get it, he will die. Therefore, the ancients said that the yang is easy to live, and the yin is easy to kill.

1. Engels scientifically defined life for the first time In the second half of the 19th century, Engels gave a definition of life: "Life is the mode of existence of the proteosome, and the basic factor of this mode of existence lies in the continuous metabolism of the external nature around it, and as soon as this metabolism stops, life will stop with it, and the result is the decomposition of proteins." "Engels' definition of life reveals to a certain extent the material basis of life, that is, the proteosome with metabolic functions.

For 100 years, this definition has been a guide to the idea of life.

2. Mankind's New Understanding of Life Since the 20th century, natural science has developed rapidly, and the relevant sciences that study life have successively entered the molecular level. Modern science has proved that after removing water from living cells, about 90% are proteins, nucleic acids, sugars, and lipids, among which proteins and nucleic acids are the most important. Biological proteins are composed of 20 heavy amino acids, which play an important role in the catalysis of nucleic acid metabolism, the regulation and control of metabolism, and the memory and recognition functions of higher animals.

Nucleic acids are composed of bases, pentose, phosphoric acid. Depending on the pentose sugar contained in the nucleic acid, the nucleic acid can be divided into ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).Nucleic acids control the synthesis of proteins and determine the properties of proteins.

It can be said that proteins and nucleic acids are interdependent and interact with each other, making the living body a unity.

3. Different definitions of life It should be said that life is a phenomenon that is difficult to define, and each professional research tends to define it in its own terms.

The physiological processes presented by organisms that are made up of substances such as nucleic acids and proteins. Metabolism and self-replication are the most basic phenomena of life. With the evolution of organisms, life phenomena have become more and more complex, mainly including stress, development, heredity, variation, movement, regulation, etc.
