Are scenes from science fiction out of reach? Where is the limit of the human imagination? Recently, a search for the soul of science and science fiction was held at the fifth annual Blue Planet Science Fiction Film Week.

On November 26, in the "Blue Planet Science Fiction Film Week · Ask Science for Answers" series salon, Zhihu's outstanding authors and researchers from many fields gathered together to open a journey of exploration with the theme of "Science science fiction and human life", to conduct cross-domain thought collision around science and science fiction, and to "ask science for answers" together.

Liu Boyang, Ph.D., Astrophysics, University of Western Australia, outstanding author of Zhihu Astronomy topics;

Song Yunjiang, popular science author, outstanding author of Zhihu Zoology topics (Zhihu "Zhan Yun"); Xu Kun, postdoctoral fellow, University of Chinese Academy of Sciences, outstanding author of Zhihu Physics topics (Zhihu "Zi Gan");

Dr. Fu Shibo (Zhihu "Doctor Philip"), postdoctoral fellow of the School of Medicine of Shanghai Jiao Tong University, and Dr. Cui Yuanhao (Zhihu "Sweet Strawberry"), associate researcher of Southern University of Science and Technology, and excellent answer of Zhihu Communication topic, participated in the activity and shared wonderful things.

When talking about the understanding of science fiction works, Xu Kun, a scientific researcher, said at the salon, "I think science may be a kind of attitude toward life, a kind of thinking logic in the face of problems."

Xu Kun believes that it is very meaningful for researchers to see what they study reflected visually in the form of science fiction.

Song Yunjiang believes that good science fiction works can not be separated from human science foundation, and need to have amazing imagination, while thinking about human nature and society.

There is a question on Zhihu, "Is it really possible to push the Earth in the Wandering Earth?"

What are the odds?" Song Yunjiang believes that this probability is zero in his answer, and he conducted an in-depth analysis based on the rocket equation, obtaining 13,000 agreements from Zhihu users. Song uses three words to define his answer at Zhihu: professional, hardcore and imaginative.
