In 1990s, China science fiction set sail again, and after more than 20 years' efforts, it finally yielded fruitful results. Liu's Three-body won Hugo Award 20 15, the highest prize in world science fiction literature. With this as a symbol, a new sci-fi craze has arisen in China's literary world, and its focus has expanded from the level of literary creation to the level of theoretical research.
If modern psychology provides an inward dimension for the development of literature and makes the profound and mysterious spiritual world of human beings resort to the pen, then with the help of modern physics and cosmology, literature will open a brand-new outward dimension and explore a deeper and mysterious cosmic dimension beyond the realistic dimension.
Italian writer Calvino wrote in the Memorandum of Literature in the Next Millennium: "Of all the values I hope to inherit in the next Millennium, one is above all else: a literature that loves spiritual order and accuracy, a wisdom of poetry, but also a wisdom of science and philosophy."
He dreams of such future literature: "condense the vast world view, Sakya and epic into the size of only one meaningful sentence." We think that science fiction is the future literature that Calvino expects to develop in the cosmic dimension.
"Huai Nan Zi" has a saying, "From ancient times to the present, it is called the universe, and the four directions are called the universe." As an important story background of science fiction, the universe is actually the unity of time and space. With the deepening of human research on the universe, the time scale and space scale grasped by science fiction are also expanding.
