It is, and never really as been, about &amp;#x27;plausible science&amp;#x27;.&lt;p&gt;just take the posterboy of American hard SF, Arthur C. Clarke. (whose writing resembles Liu Cixin a lot). A lot of his stuff is straight up fantastical or cosmic. Childhood&amp;#x27;s end for example (sort of TBP like) or The City and the Stars. The science in either one isn&amp;#x27;t really plausible. Hard science fiction was always distinguished by ditching characters and traditional adventure or hero narratives for ideas. It was never about writing a physics PhD thesis.</text><parent_chain><item><author>schwartzworld</author><text>Sure.&lt;p&gt;Just like harry potter explores what happens if you have a cloak of deception or time turner.
