Is any hard science fiction still being written?

Yes, there might be. 'Doctor Who' often dabbles in some hard science - fiction concepts like time dilation, parallel universes, etc. though it's also a mix of other elements.

Some of Liu Cixin's novels were hard science fiction, while others were soft science fiction. Liu Cixin's " The Three-Body Problem " series was considered a hard science fiction novel that involved supernatural forces, alien civilizations, time travel, and other scientific concepts. In the novel, the author depicted a worldview based on physics and astronomy and explored the depth and possibilities of these concepts. However, Liu Cixin's other works, such as Ball Lightning, Wandering Earth, and Supernova Era, also contained some soft sci-fi elements. In these novels, the author explored some more abstract and philosophical concepts, such as the fate of mankind, the development of civilization, the choice of morality, etc. These concepts had nothing to do with science, but they could also attract readers 'interest and thoughts. Therefore, Liu Cixin's works covered both hard science fiction and soft science fiction. They challenged the rigor of science and expressed the depth of philosophical thinking.

Avatar was a sci-fi film based on modern biology and physics. It explored the story of humans entering Pandora and establishing civilization there. In the movie, there are many technological and biological differences between the creatures on Pandora and humans. These differences are very different from the biological and technological levels in our real world, so it can be considered a hard science fiction movie.

Hard science fiction is a sub - genre of science fiction that emphasizes scientific accuracy and plausibility.

I recommend the following science fiction novels: 1. "The Key to the Infinite Universe" was a science fiction novel by the Chinese author Tian Weixin. It was about a high-energy physicist who crossed the continent of Europe and Asia, experienced life and death, and foiled a plot to save the world. 2. "The Doomsday Tyrant" was a doomsday crisis novel by the Chinese author Mao Huanhuan. It was about a student who was reborn ten minutes before the apocalypse. In order to survive, he entered the university of the apocalypse and left no regrets. 3. "Quinary Creator"-A novel about evolution and mutation of non-singular matrices by a Chinese author. It tells the story of gene editing becoming rich, but unexpectedly causing the end of the world and extreme operation to save the world. I hope you like my recommendation, Mwah ~😗
