What is a Dyson Sphere?

^[1] "Dyson Ball" is a theory proposed by Freeman Dyson in 1960. The so-called "Dyson sphere" is actually an artificial celestial body with a diameter of 200 million km, which is used to wrap stars to mine stellar energy. This is a natural nuclear fusion reactor that uses stars as its power source.

Using existing or near-future technology, Venus Dyson sphere structure can be manufactured to protect Venus from sunlight and cool down the earth. It does not involve any new physical theory. You can use large electromagnetic catapults to launch raw material powder barrels into 3D printing on earth orbits to make giant spaceships, space colonial satellites, etc., first create a large manned spacecraft with a plasma engine to fly to Venus orbit, and land at the top of Venus' atmosphere (close to Earth The altitude of air pressure and gravity acceleration) floats as a floating city (the density of floating cities is lower than the atmosphere there). The floating city inner factory extracts Venus' atmosphere, uses carbon dioxide inside to make graphene as a building material, and replicates another floating city factory. Carbon dioxide can be reduced into the molten metal liquid at high temperature to directly make graphene and electrolyze oxygen. Oxygen is used as the main buoyant gas inside the floating city. Of course, a certain amount of nitrogen and carbon dioxide need to be added to meet the earth's air composition. Countless floating cities are connected with carbon nanotube ropes to form a Dyson sphere, which blocks the sun and cools Venus' atmosphere. Decreasing carbon dioxide can also reduce the greenhouse effect. The surface of the Dyson ball uses a graphene superconductor as a wire. After being energized, a global magnetic field is generated, which deflects the solar wind to protect the atmosphere. Residential community cities can be made into spherical or cylindrical shells, which are transparent on one side and opaque on the other. The shell rotates slowly to control the amount of sunlight passing through and produce a circadian rhythm. In this way, gravity, oxygen content, atmospheric pressure, global magnetic fields, and circadian rhythms are all available. Together with water and other elements extracted from the atmosphere, it can completely support a new earth's ecological environment suitable for permanent generations to reproduce. After a few years, Venus's atmosphere will cool down to the level of the earth and form the sea, and then the biosphere can be transplanted from the poles, and Venus mining can also be started.

Excess graphene can make solar sails for sale to Earth and Mars colonies, including excess oxygen capacity. And import the moon's soil, Titan's oil and gas, and Europa's ice cubes to form a prosperous and sustainable solar system interstellar trading circle.

High-temperature and high-pressure Venus cars can be driven by high-temperature resistant air compressors and pneumatic devices instead of motor systems.

Dyson Ball Character Profile

Dyson

Freeman Dyson (1924-) was born in the United Kingdom. He studied at Cornell University in 1947, officially settled in the United States in 1951, and became a professor of advanced research physics at Princeton in 1953. Professor Dyson is not only an excellent theoretical physicist, but also a wise philosopher who cares about human destiny and yearns for the infinite universe. During his lifetime, he traveled in the fields of mathematics, particle physics, solid state physics, nuclear engineering, life sciences, and astronomy, and was determined to explore the unknown world. In his early years, Professor Dyson passed the Nobel Prize in Physics for the giant of quantum electrodynamics. The spin wave paper published in 1956 has received numerous citations, and is one of the heavyweight papers in the history of physics. Dyson said that "spin waves" is perhaps the most important contribution of his life. Professor Dyson has served at the Institute for Advanced Studies in Princeton for forty years. Dyson has received many awards: the Hughes Medal of the Royal Society of London, the Max Planck Medal of the German Physical Society, the Oppenheimer Memorial Award, and the Harvey Prize of the Haifa Institute of Technology in Israel Wait.

He is the author of "All-round Infinity", "Weapons and Hope", "Cosmic Waves", "Imagined Future", "Sun, Genome and Internet: Tools of Scientific Revolution", "World in Imagination", The scientific community and the general public have aroused great repercussions.

Freeman Dyson was not only interested in mathematics, physics and chemistry when he was a child, but was very fond of reading literary works. Without the foundation of the liberal arts laid in his early years, his "Cosmic Wave" must be unpredictable in the vast sea of books, and will not become a best-selling book, and his "All-round Infinite" must have a very limited sales. Freeman Dyson's books are pretty good in almost every book, not to mention the depth of his thinking, his elegant text alone is full of charm. Chinese translations of his "Cosmic Waves", "All-round Infinity", "The Sun, the Genome and the Internet", and "The Imaginary World" have been published. In addition, he wrote "From Iros to Gaia", "Origin of Life", "Weapons and Hope", and more. Like many learned writers, he quotes a famous celebrity quote at the beginning of each chapter of the book that is relevant to the subject of the chapter. Without the skill of "reading and breaking 10,000 volumes," it would not be possible to "quote like a god".

Dyson Ball main works

"Cosmic Waves"-Technology and the future of human introspection

Dyson, the first giant of quantum electrodynamics, is not only an outstanding great scientist, but also a wise philosopher who cares about the destiny of mankind and yearns for the infinite universe. This book is a memory of his fifty years of scientific work. He compares scientific life to the journey of a personal soul. It romantically and vividly describes the style and achievements of many famous scientists such as Oppenheimer, Feynman, Taylor and others. Furnace, life technology, and space exploration research process and controversy, while deep thinking about the development of science and technology and human future.

Infinite Omnidirectional: Why Life Is So Complex

Professor Dyson is a familiar person in the scientific community. With superb intelligence and extraordinary courage, he crossed the threshold of science and thought about the close connection between the universe and human mind. The book is divided into two parts. The first part is "Why is life so complicated?" In this book, the author explores the diversity and consistency of life, complexity and simplicity, and guides readers step by step to unlock the mystery of the origin of life, and then infers the ultimate future of humanity. The second part, "Nuclear Winter, Seeing Butterflies," reviews the dilemma of human morality and ethics in the highly developed modern science and technology. From military balance, nuclear weapons development, and the Star Wars plan, it talks about international politics and the human destiny of the 21st century . Professor Dyson impressed many people with his brilliant experience of observing the butterfly's life and dancing. ^[2]

Imagined Future

In 1979, Dyson expressed his concern for the human condition through his personal biography in The Waves of the Universe. In 1988, Dyson explored the diversity of Life and further thinking about the interaction between humans, technology and morals. In this book, the author uses his fluent thoughts and beautiful writings to draw inspiration and imaginatively anticipate the future of mankind. Through the colors of literature and science fiction, this book points out the fate of tomorrow's science, predicts the evil and beauty of future technology, and measures the evolution of humankind with ten, hundred, millennium, and even infinite time. . At the same time, he called for technology to go hand in hand with ethics. The future imagined by Dyson is like roaming the boundless universe by a time machine, and the colorful world is presented to human beings. ^[2]

This book tells lively stories, whether real or imaginary, whether scientific or artistic, the intention is not in science and technology itself. The author examines human behavior in the development of material civilization in a broad space, and believes that all science and technology have ethical characteristics ^[2]
