In the universe, the probability of life on Earth is extremely low, because things with extremely low probability require countless low-probability events to interweave with each other to make it possible.
However, it is this interweaving of small probability events that makes our lives exist, and everyone comes into the world as the result of countless small probability events, so some people say: "Each of us is a small probability event." ”
So how low is the probability of the birth of a human being?
What are the low-probability events that are intertwined with each other to allow life to exist?
How do humans discover and unravel these low-probability events?
1. Born with low probability.
About four billion years ago, life began to flourish on Earth.
The probability of life on Earth is extremely low, because it requires many low-probability events to interweave to make it possible.
One of the earliest low-probability events is the production of hydrogen.
About 90% of the matter in the universe we live in is a gas composed of hydrogen atoms, but most hydrogen atoms are hydrogen nuclei, which is a more stable state.
It is only in extreme circumstances that hydrogen atoms undergo nuclear fusion, which produces energy.
In extreme environments, the conditions for hydrogen nuclear fusion are very harsh, usually requiring tens of millions or even hundreds of millions of degrees of high temperatures, in addition to high pressure, in order for nuclear fusion reactions to occur.
The natural conditions on the earth cannot meet these conditions, so the hydrogen fusion reaction on the earth cannot take place, but the core of the sun is a huge fusion reactor, a huge energy generator, and the energy source of all life on the earth.
The process of solar energy generation is that in the core of the sun, the hydrogen nucleus undergoes a fusion reaction, thus forming a helium nucleus and producing energy, which is the process of sunlight production.
The temperature of the core of the sun is about 100 million degrees, and the pressure is correspondingly high, enough for the hydrogen nuclei to fuse, so the sun can produce energy to provide energy for life on Earth, which is the low-probability event 1: the core of the sun produces energy.
In addition, the energy generated by the sun is released in the form of light, which requires light to be reflected and refracted in the process of propagation, so that light can reach the earth and provide energy for life on the earth.
However, in the universe, there are still a lot of dust and stars, and the existence of these dust and stars will hinder light, so the propagation process of light is also a low-probability event.
In the process of light propagation, when light encounters dust and stars, there will be scattering phenomena, so that the propagation path of light will change, so there is no dust and stars, there will be no light emission and refraction, there will be no sunlight, and there will be no life on earth, which is low probability event 2: light propagation.
In addition to the propagation of light, there is also a low-probability event, which is the position of the Earth in the solar system, which is also an important reason why the Earth can give birth to life.
In the solar system, the Earth is located in a suitable position from the Sun, which is just right for the temperature on the Earth to allow life to grow and reproduce on the Earth.
However, it is not accidental that the Earth is in a suitable position from the Sun, but is formed by the fact that the Earth was pushed outward due to the gravitational pull of Jupiter during the formation of the solar system.
Therefore, the Earth can be in a suitable position from the Sun, which is also a low-probability event.
2. The "nanny" of the earth.
Life on Earth is possible thanks to the Moon.
Life on Earth is also possible thanks to the Moon.
Before life existed on Earth, there were many impacts on Earth that would have endangered life on Earth, but life on Earth did not become extinct, all thanks to the Moon.
Life on Earth is possible thanks to the Moon.
The Moon is a satellite on the Earth, and it has a huge gravitational pull, which can make objects on the Earth, such as meteors and asteroids, constantly attracted to the Moon and thus hit by the Moon.
Before life existed on Earth, there were many impacts on Earth that would have endangered life on Earth, but life on Earth did not become extinct, all thanks to the Moon.
Life on Earth is possible thanks to the Moon.
These impact events also provide a possibility for the creation of life on Earth.
Before the emergence of life on Earth, there were many organic molecules on Earth, and these organic molecules were the precursors of life on Earth.
However, between these organic molecules, there must be enough energy to form life, and this energy is generated by impact events that life on Earth has experienced before.
In the impact event, it causes friction between the organic molecules, which causes the organic molecules to produce energy, and this energy causes chemical reactions between the organic molecules, thus forming new organic molecules, which in turn can produce energy, thus forming more complex organic molecules, which is the process of life generation.
However, in the process of generating life on the earth, if there is no moon, the impact events experienced on the earth will be very frequent, so that the process of life on the earth will become more rapid, and the life on the earth will lose its diversity, so the life on the earth can form diversity, and it is also because of the existence of the moon, so the moon is the "nanny" on the earth.
3. The Birth of Humanity.
After the emergence of life on Earth, it took about four billion years for life to gradually develop into advanced organisms.
In the process of life development, it has also experienced many "big updates", and these "big updates" are all low-probability events.
In the process of life development, it has also experienced many "big updates", and these "big updates" are all low-probability events.
In the initial stage of life, life on the earth is dominated by single-celled organisms, and the development of these organisms is affected by the environment, but with the passage of time, changes in the environment will also cause organisms to mutate, so as to form new organisms, which is the process of biological evolution.
However, in the process of the evolution of life, it will also be restricted by the laws of nature, and some organisms will form a stable state in the process of adapting to the environment, which means that the form of organisms will no longer change, which is the limit of biology.
However, in the process of the evolution of life on the earth, there is no such limit state, so that life on the earth can develop diversity, so that life on the earth can become rich and colorful, so that a high-level intelligent civilization can be formed.
The birth of human beings is also a low-probability event for the evolution of life.
The birth of human beings is also a low-probability event for the evolution of life.
In the process of the evolution of organisms, they will be affected by the laws of nature, and there will also be low-probability events, which are a link in the evolution process of organisms.
There are also many low-probability events in the birth process of human beings, such as the probability of parents meeting and falling in love, the probability of giving birth to offspring, etc.
In the process of human birth, there are also many low-probability events, such as the probability of parents meeting and falling in love, the probability of giving birth to offspring, etc.
In the process of human birth, there are also many low-probability events, such as the probability of parents meeting and falling in love, the probability of giving birth to offspring, etc.
epilogue
In the universe, the birth of each life is unique, and in the process it goes through, there will be countless low-probability events intertwined with each other to form life.
"Each of us is a small probability event. ”
It is precisely because each of us is a small probability event that our life becomes more precious, and it is also the meaning of each of our lives.
