The physical world we live in is made up of many elements, and oxygen and silicon dominate the earth, with 48% of the earth's crust being oxygen, and the second most important being silicon, which is also more than 26%. Amazingly, these two elements together make up 75% of the total mass of the earth's crust!
In the universe, the distribution of elements is even more amazing. According to astronomers, 75% of the universe is made up of hydrogen, helium accounts for about 24%, and the other elements together add up to less than 1%. This abundance of hydrogen and helium in the universe is closely related to the grand theory of the universe.
About 13.8 billion years ago, the universe began to expand from the original "singularity", and the temperature and density were infinitely high at the beginning, and gradually decreased in temperature and density as time and space expanded. Scientists deduce that within 10 seconds after the big **, the cosmic temperature drops to 3 billion degrees Celsius, protons and neutrons combine to form a relatively stable helium element, and free protons and free electrons combine to form hydrogen elements.
Inside the star, nuclear fusion reactions are constantly underway, that is, the process by which the element hydrogen is converted into the element helium. However, even so, hydrogen is still the highest proportion of matter in the universe. For a solid planet like Earth, the proportion of hydrogen is only 075%, helium is rarer.
Earth's gravity is relatively poor at binding hydrogen and helium, causing them to escape from the atmosphere. The material composition of the universe is amazing, and the abundance of hydrogen and helium elements fills the space of the universe, weaving a mysterious cosmic code.
In this long history of the universe, the changes of the elements are like the heartbeat of the universe, recording the evolution of the universe. From the initial moments of the big ** to nuclear fusion inside stars, the elements play a key role in revealing the mysteries of the universe. And it is the changes of these elements that make up the diverse faces of the universe as we see it.
From the microcosm to the macrocosm, from the fusion of atomic nuclei to the expansion of interstellar space, the elements are everywhere, playing the protagonist of the cosmic drama. As the poet described: "The sea of stars turns into dust." "In this infinite universe, the elements are the basic building blocks of the universe, the witnesses of time, and the source of life.
The existence and evolution of the elements not only provide a scientific explanation for the formation of the universe, but also lead us to think about the origin of the universe. Although the composition of the elements of the universe was not known at the time, the origin of the universe was explained with astonishing accuracy and laid a solid foundation for cosmology. This kind of scientific foresight and quality makes the grand theory of the universe one of the key clues to analyze the mysteries of the universe.
Looking back at the evolution of the universe, we can hear the whispers of the elements in the long river of time. Hydrogen and helium together compose the chapter of the universe, they are the essence of the mother of the universe, and they are the notes that flow between the stars. In this boundless universe, the distribution and evolution of the elements are like a melodious symphony, playing the magnificent movement of the universe.
With the continuous advancement of science and technology, our understanding of the universe is also deepening. As the most basic constituent unit of the universe, the unique properties and interrelationships of elements lead us to think about the origin and evolution of the universe. The material composition of the universe is a complex and complex system, and the elements are the core elements of this system, which is one of the keys to the mysteries of the universe.
In this universe in which we live, the elements carry the information of the universe and record the changes of the universe. From the cosmic grand ** to the formation of nebulae and then to the birth of stars, the existence of elements runs through the entire process of cosmic evolution. They are like a notebook of the universe, recording the changes of the universe and constructing the mystery of the universe.
The wonder of the elements lies in their diversity and interconnectedness. It is precisely because of the combination and change between the different elements that the universe presents a rich and colorful scene. From the microscopic atomic structure to the macroscopic arrangement of galaxies, the existence and evolution of elements constitute the multi-layered structure of the universe, providing clues and breakthroughs for us to interpret the universe.
And in this boundless universe, the dominance of hydrogen and helium is even more remarkable. They seem to be the soul of the universe, running through the universe throughout. Hydrogen, the most abundant element in the universe, bears witness to the origin of the universe;The helium element, on the other hand, was formed at the moment after the universe became large, injecting a stable elemental foundation into the universe.
In this universe where the elements are intertwined, we can't help but wonder: is the existence of elements an inevitable choice of the universe?Is the evolution of the elements a product of the evolution of the universe itself?These questions challenge our understanding of the nature of the universe and lead us to explore the unknown.
As science continues to evolve, we may be able to understand the mysteries of the elements more deeply and unlock more secrets of the universe. Elements, like the code of the universe, hide the origin, evolution, and future of the universe. In this infinite universe, the elements are the key to our understanding of the universe and the title page of the mysteries of the universe.
Whether it is the singularity of the big ** theory or the metamorphosis of the elements inside the star, it is the main chapter of the cosmic drama.
