Entropy is a hard science fiction story.
Many people have never read hard sci-fi, and some might be (rightly?) confused about what hard sci-fi is all about.
The following article by Eddison Munroe gives an excellent overview of what to expect from hard sci-fi. https://rtbookreviews.com/best-hard-science-fiction-books
As a hardware/software engineer, and after reading a lot of hard sci-fi myself, it’s no surprise that Entropy covers many of the tropes mentioned in the article. Entropy:
“places great importance on scientific accuracy and consistent logic.”
“creates a plausible narrative based on current scientific understanding.”
“creates a sense of realism that draws readers in and encourages them to think critically about the implications of scientific progress.”
“creates complex and intricate societies and technologies that reflect the impact of scientific progress on human culture”
“can lead to thought-provoking stories that question our understanding of technology, the cosmos, and humanity’s role in the universe.”
“provides a unique and fascinating perspective on the possibilities of the future, grounded in scientific principles and exploring the implications of scientific progress on human society.”
“offers a compelling and thought-provoking exploration of humanity’s potential future, all while remaining rooted in sound scientific principles.”
It’s okay to be left thinking about life, the universe, and countless possibilities after reading a hard sci-fi story. That’s its job.
