The universe began to be bred after 13.8 billion years ago, after the birth of the Singularity Bang, the universe began to be bred with a long time and space. In the Hongmeng period when chaos was first opened, cosmic energy interacted wildly in the space of extreme temperatures. The universe expanded to 1600 trillion kilometers and the temperature reached 10 billion degrees Celsius, which activated the nuclear fusion anti-epidemic, and the hydrogen element in the universe was born. Hydrogen is honored to be the initial starting point of the nuclear fusion reaction of stars in the universe. In other words, all elements in the universe are formed from the nuclear fusion of hydrogen elements. It consists of hydrogen atom and helium atom . The hydrogen element is the basis of matter in the universe.
In the initial stage, a new element was born, that is, the lithium element, which was produced by the big explosion of the gravitational collapse of the star. The lithium element is the beginning of the formation of life in the universe. The lithium element wandering in the universe forms a huge molecular cloud of hundreds of light years. These gathered giant molecular clouds have increasingly large mass until gravitational collapse occurs inside, and the hydrogen element inside undergoes strong nuclear fusion. The huge energy released creates the first star in the universe.
For a long time, the universe continued to expand and expand, forming a giant molecular cloud, which repeatedly experienced gravitational collapse. In this way, more and more stars in the universe were born, and more elements were created in the nuclear fusion reaction of stars. From then on, there were oxygen element , carbon element, nitrogen element , etc. in the universe, which formed a large amount of nebula dust in the universe. The birth of the first planet in the universe is attributed to these giant molecular clouds, which have evolved and gathered over billions of years. Finally, the huge galaxy celestial system was formed.
by chance, on a planet, the first single-celled organism was discovered, and life was found in the universe. This kind of life is called carbon-based life . Carbon-based life is the basis of life of organisms, and silicon-based life is a form that exists outside of carbon-based life . The biggest feature of carbon-based life is complexity and variability, and it cannot survive if it is separated from this planet. One carbon element has four free electrons , and the electron reduction and oxidation properties are relatively powerful. Carbon-based life is suitable for survival under stable conditions, and later we called this planet Earth.
After billions of years of evolution, it has formed more complex polymer organisms, and nature has begun to nurture more and more species. Until the emergence of the intelligent race of mankind opened up an unprecedented civilization on earth. All elements that make up the human body come from distant stars. When looking up at the galaxy, they have imagination and attachment to the deep universe. Perhaps because the components of our bodies are from distant stars.
Everything on Earth is the element forged by the supernova explosion . From the depths of the distant galaxy, as time goes by, the entropy value of the universe continues to increase, resulting in the disorder of the universe's material energy. Since time is in a linear state, the entropy value of the universe continues to increase from the moment it is born, and this process is irreversible. Human life is also in a state of increasing entropy.
Human beings are based on organic matter. The conditions for the survival of carbon-based life must have a stable ecosystem. Carbon-based life is difficult to withstand high temperatures, low cold, erosion of bacteria and radiation. The earth provides an ecological environment that conforms to carbon-based life and survival. In the amino acid that constitutes carbon-based biological , carbon elements are connected to amino and carboxyl .
Therefore, all known organisms on the earth belong to carbon-based organisms, and the energy source of carbon-based organisms is carbohydrate . Among carbohydrates, carbon atom is one of the elements from ancient times and is the most basic element that constitutes carbon-based organisms. Carbon atoms are connected by a single bond into a chain, and the oxidation of carbohydrates controlled by enzymes can release the energy needed by the body.The waste produces water and carbon dioxide . The enzymes in carbon-based organisms can catalyze specific reactions according to the shape and right-handedness of the molecules, identify and regulate the metabolism of their own numerous and different cells.
The gorgeous universe is full of dangers. The tiny earth has a stable ecosystem. The atmosphere isolates cosmic rays and ensures the ecological environment of carbon-based organisms. Oceans and mountains and rivers give birth to thousands of species, and fresh water in the air guarantees the metabolism of carbon-based organisms. The accidentality of the emergence of intelligent creatures becomes the inevitable result of cosmic life. In the vast universe, it is difficult to see the existence of the earth because it is too small as dust, but it is a paradise of survival carefully created for carbon-based organisms. Can it be argued that humans came from the depths of the distant universe, or by chance, were sent to the earth by other distant planets. Human beings have survived on Earth for 4.6 billion years. Human beings were born 5 million years ago. In other words, dinosaurs were born after 65 million years of extinction at the end of the Cretaceous period.
So, outside the earth, are there other forms of life! We don't know about this problem. But should we adjust our exploration ideas? We cannot search for alien civilizations based on the conditions of carbon-based organisms. After all, human civilization's understanding of the universe is just the tip of the iceberg and a drop in the ocean. In the vast universe, is the survival conditions of carbon-based organisms satisfied?
