What hard scifi books could you recommend?

Hello! Could you please recommend some hard science fiction books? I am struggling to find a good one. My favorites are Blindsight and Echopraxia by Peter Watts, but I have failed to find anything similar.

I also enjoyed The Martian by Andy Weir and The Murderbot Diaries by Martha Wells, though in my opinion, these aren't quite what I would call hard science fiction.

Additionally, I enjoyed books that blend fiction and non-fiction, like Harry Potter and the Methods of Rationality by Eliezer Yudkowsky and Gödel, Escher, Bach by Douglas Hofstadter.

What are your favorite hard science fiction books?

    Two recommendations:

    The Expanse series by James S.A. Corey- this one I can credit with both really compelling characters & worldbuilding and (largely) realistic space travel physics. It also covers a kind of gap that most space travel sci-fi doesn't cover- the societal transition between humanity being able to traverse only our native solar system and the wider universe.

    Project Hail Mary by Andy Weir- if you like The Martian I think you'd have no problem enjoying this one. The main character(s) definitely spend most of their time actively thinking through how to solve technical problems, but the underlying plot conflict is fascinating too.

      I've already read Project Hail Mary and really enjoyed it, but found it somewhat naive, so it didn't quite satisfy my craving for hard science fiction. But anyway, I'll look closely to what Andy Weir writes, since I like a lot of his novels.

      How is The Expanse hard scifi? I haven't read the books, only seen the tv show, but some of the basic premises of the story and setting are pretty much space magic. I know it has hard scifi elements regarding space travel, but that's just one element out of many. If OP doesn't consider The Martian entirely hard science fiction, I don't see how The Expanse would qualify.

        <snark>The Expanse is hard sci-fi because it doesn't include FTL.</snark>

        …Or inertia suppression, mostly. I kid, a bit, but one way to rank sci fi by hardness is how many currently-known laws of physics it introduces means to violate. (There's a quote about this from someone much more authoritative than me that I couldn't find in a few minutes of searching—if anyone has it offhand, please do share!) Not choosing faster-than-light travel is (a) unusual, and so makes your setting stand out; and (b) also makes the setting unfamiliar to modern societies, which again makes it stand out.

        (Let me explain briefly: modern societies are essentially scale-invariant. How long does it take the Prime Minister of Luxembourg to receive missives and send orders to the far corners of his domain? What about the US, a country almost 4,000 times larger? In both cases, the answer is zero from the perspective of human communication. Within the Earth's gravity well—where every living human being resides—the speed of light is fast enough that communication latency is irrelevant. The scale of your polity has little impact on the mechanics of its governance, at least technically. On the scale of the solar system, or especially across multiple star systems, this is no longer the case. Amusingly, this aspect probably would have been more familiar to people prior to the invention of the telegram, when even small countries were large enough to take hours to days for messages to cross.)

        Anyway, the Expanse's main law of physics violation is the Epstein drive, which… basically can't be made to make physical sense, to the point the authors didn't even try. There's other stuff that doesn't add up (don't think too hard about Ceres or Eris or try to work out any of the orbital mechanics), but it strongly appears to be more "didn't do the math" than "invented new physics". And in the broader context of sci fi, that's… reasonably hard.

          From my point of view the Epstein drive is a bit of a problem, but the p. m. is the biggest one. That's magic, nothing less, and it is one of the main things the story revolves around. There were some other magical things teased in the last season of the show, but I haven't read the books, so maybe they could be explained, though I doubt it.

          The Expanse is no doubt harder than Star Trek, but that's not very difficult. I think that what is considered hard scifi has shifted in recent decades as mainstream scifi became less technical and more psychological. Personally I'd put The Expanse around the middle of an imaginary soft - hard scale.

            The Expanse spoilers

            (Note I've only read the first book here, so this is from that perspective.)

            Yeah, the protomolecule is magic, but it's also Weird Alien Shit™. IMO, sci fi mostly gets a pass on hardness from Weird Alien Shit as long as it remains incomprehensible to the viewpoint characters.

            That said… it violates relatively little physics. It's got inexplicable matter-to-energy-conversion (not really physically impossible), inertia suppression (not physically impossible), and everyone's favorite implausibly-effective biochemistry (not physically impossible, but very unrealistic); but it is still bound by the speed of light and conservation of energy.

            I mean, broadly I agree with you. The Expanse is solid space opera; it isn't, and isn't trying to be, diamond-hard sci fi. It's tough to place it on a scale without establishing a scale, which I don't have broad enough experience with sci fi to do confidently; but yeah, it's probably somewhere (in the vast, empty gulf) between Iain Banks's Culture and Kim Stanley Robinson's Mars. I'd honestly put it in the vicinity of Alastair Reynolds's work, though obviously there's loads of room to quibble.

            if I remember the story correctly. The epstein drive then feels more like it needs to be explained for realism than the p.m. Since the p.m. has a plot reason for being "space-magic".

            W.r.t. where it ranks on the soft/hard scale, I like to compare scifi to fantasy for this. If we put Tolkien then on one end and on the other end it turns into historical fiction instead, I'd then place the expanse on the scifi scale somewhere where I'd place ASOIAF for fantasy. Yeah there's dragons, some magic and the things beyond the wall so it's not super hard, but it's also not like there's wizards, orcs, elves and dwarfs (okay maybe one) running around all the time. GRRM calls it "low-magic", with the amount of magic increasing as the story progresses. I think the Expanse hits a similar spot. Whether that's the middle depends on what you put on the extremes.

              For me hard scifi means that the story is centered about encountering and interacting with things that are plausible, exploring that interaction and building the story on what comes from that, meaning that unexplained things can be there, but the "hard" part is where the focus is.

              Imo this applies for example to some young adult focused books by R. A. Heinlein that would not normally be in some hard scifi lists more than to The Expanse.

            It does not matter in the scheme of things since it’s still used basically as a macguffin of sorts.

            It’s certainly not the hardest sci fi and writing wise struggles in a lot of narrative and characters spots(although it shares that with hard sci fi I suppose) but I think it’s more than fine to start someone there.

I overall really enjoyed the series though, and I don't really care about the "hard sci-fi vs non-hard sci-fi debate" but if I had to make a choice based on the entirety of the plot I think I'd put it in the latter.

        Eh, I liked watching The Martian but I wasn't a fan of the writing style in Project Hail Mary. Both stories are a bit more "survival horror" than sci-fi imo. The Martian definitely gets scored high in "realism" for me.

        Whether you consider The Expanse hard sci-fi is going to depend on your own criteria. For me it's about realism of tech; I'll allow some unexplained/understood phenomena to create a plot. In The Expanse the "space magic" is 100% a feature of the unknown and that is the contention of the series. Humans are bound essentially by the physics we already understand. The politics and socio-economics are also well modeled.

        I'd definitely call it harder than most popular sci-fi. Much harder and you're constrained to our solar system.

        There are one or two bits of serious space magic, but IMO it's at least a proper space opera with strong physical rules for navigation in space. About as 'hard' sci fi as maybe Star Trek TNG or Stargate SG-1's early Showtime seasons.

        So I wouldn't recommend it if you're a stickler for the 'hard scifi' bits, but otherwise it's worthwhile.

        On the other hand, James SA Corey's new series seems to be a bit harder (and quite a bit grimmer). Closer to Dune levels of hardness. Definitely worth reading the first one since it'll likely be a decent length series and the authors have already proven their ability to land one fantastic series.

              It’s hard to look back at Leviathan Wakes without the context of when I read it. I was a grad student flying to work at UCONN for a week. It hooked me on the plane and I had to pick up Caliban’s War before flying home. I remember leaving lunch with my advisor early because I was like “sorry this book grabbed me and I need the second one for my flight home.”

              In retrospect, the first book of expanse is my least favorite. I’m excited to try the first book of this new trilogy but hopefully having to wait for book 2 this time around doesn’t diminish the experience.

    I've read a very large amount of sci-fi over the years, so It is hard to separate the hard sci-fi from the rest, but I think I can recommend a few. I'm going to try to avoid summarizing them as you should be able to easily find that info if you want it, but I'd rather not spoil by default.

    Seveneves by Neal Stephenson was an enjoyable read. It goes a bit off the rails in the later section, but I think the vast majority (first part of the book) is a really scientifically grounded sci-fi story.

    The jackpot trilogy (the third book coming soon) by William Gibson could probably be considered hard or at least semi-solid sci-fi and I really enjoyed it and I can't wait for the final book. Amazon picked up the series for a show a few years back (The Peripheral), but killed it off after season 1/book 1, which I consider a travesty as I really liked the show despite its deviations.

    I'd also recommend the Ian M. Banks "Culture" series, though again, it is hard to say it is considered true "hard sci-fi". The series has a lot of books in the same universe, but they are generally pretty stand alone and do not really need to be read in a specific order though it is probably better to start early in the series so you get a feel for the universe. I started with Consider Phlebas.

        Like his long passages on the correct way to eat cereal, I suspect Neal is too popular and too good a writer for editors to delete certain bits of his writing. And honestly some of those bits are quite good, so I understand his instinct to 'ship' them to an audience even if his books might be a bit cleaner without them.

        My personal theory is that Stephenson's books all come from some very cool basic though or premise and in some of his later books he starts wondering "ok, but what are the weird long term implications of this story" and he actually ran with it in Seveneves, for better or worse. I think because of the general backlash to this, when he did wanted to do it it again he wrote the crazy part as a sequel (normal Reamde followed by bonkers Fall). FWIW, I didn't hate the last part of Seveneves so much as think it should also have been a weird follow up book. That would have also given him more time to flesh out the new weird stuff and be less rushed.

But... since you've read and liked so many of Stephenson's books, and even read Reamde to which Fall is a sequel, then yes I think you should read it. It has some really fascinating ideas in there that really stuck with me and some of which feel prophetic in a Gibson-like way (I wish I could elaborate, but I don't want to spoil anything).

    I will always recommend the Red Mars trilogy by Kim Stanley Robinson. I mentioned it in a post a few months ago, so I’ll just quote my comment again here.

    So, I have strong feelings about the sci-fi genre. I think many “sci-fi” stories are actually what I call science fantasy. Functionally they are fantasy books that have a futuristic setting instead of a magical setting. They can be fun stories, but they are mostly just for entertainment. Books like Ready Player One fall into this category. I like that book, but I don’t consider it sci-fi.

    Where sci-fi really shines is when it uses a futuristic setting to explore the human condition in a way that isn’t possible in present day fiction. Books like Speaker for the Dead fall into this category. The futuristic science is absolutely there, but the story isn’t about exploring cool science toys. It’s about people. It is philosophy, societal dynamics, etc. It’s about humanity, not science. This category of stories is what I consider true sci-fi.

    Kim Stanley Robinson is a master of this type of sci-fi. Red Mars is a near future story (year 2061 to start, and still a plausible achievement for our current technology). It’s about a colony founded on Mars and the resulting society that they develop. It addresses societal dynamics, politics, economic systems, the clash between industrialism and environmentalism, mental health, interpersonal dynamics, and so much more. Absolutely fantastic, and well worth the read. And unlike some trilogies, it doesn’t seem to fall off at the later books. I personally think Blue Mars, the last book, is the best in the trilogy (although it is certainly slow).

    Based on your post, I think it would be a perfect fit.

      That's cool! Thank you!

      I've thought a lot about what defines hard science fiction as a genre. Beyond using futuristic settings to explore humanity, I believe there should be real scientific hypotheses underlying the fictional technologies that shape these settings. After all, that's what makes it science fiction.

      Robert Heinlein was a master of such exploration. While his books may seem somewhat outdated today, I still enjoy the human aspect of his stories. One of my favorite books is The Moon is a Harsh Mistress. In this story, one of the main characters is a computer that became so complex that it gained sentience and developed a sense of humor. This computer felt empathy toward people who were surviving in the lunar colony and helped them become free from Earth's government. It's a very inspiring story.

          If you use my metric for science fantasy (and I freely admit this isn’t the same as the general consensus seems to be), Green and Blue Mars are still absolutely science fiction.

          For me, the distinction isn’t about the science at all. The “science” is just a setting to explore humanity. For example, Speaker for the Dead makes way more scientific assumptions than the Mars trilogy even dreams of, and everyone seems to agree that it is science fiction. If your metric for hard science fiction is scientific plausibility, then blue mars is way closer to science fiction than many of the great sci-fi works.

          To be perfectly honest, I don’t remember there being any significant increase in scientific ability in Green or Blue Mars (although I may have forgotten some). They mere more able to work at scale, but that is exactly what happens as time passes. The most fantasy element in the trilogy is the gerontological treatment, but that happens in Red Mars. And with the state of CRISPR today, that isn’t even very far fetched.

            Just to add to your great points here, though you could probably get about as many definitions of hard science fiction as there are readers. I think it ultimately comes down to how the author uses science in their stories. Do they just make stuff up that sounds "futuristic" or do they apply scientific method and rigor to their scientific extrapolations. While Kim Stanley Robinson clearly makes up plenty of things that aren't possible today, his approach still follows the scientific methodology and there is a great internal consistency within the universe. I think hard science fiction is not really about how "accurate" it is, but how it is part of the story. Does the futuristic inventions just exists as means to an end to get a specific space plot going, or do the technological and scientific progress proposed in the story have a central focus point for the story. I mention Greg Egan all the time, but some of his stories is technically pure fantasy as he makes up new universes where the laws of physics work differently than our own (like in The Clockwork Rocket), but it will be sort of ridiculous to say he doesn't write hard sf.

          Yes, it is a good story to start. I also could recommend Double Star and Stranger in a Strange Land. But be aware that it was written 65-70 years ago and may feel outdated.

      Actually, the book starts off in 2026, not 2061. Personally, this makes the book very interesting, as it seems to speak to the world that could have been when they were published in the mid-1990s. The first 100 were in their 40's when the book begins, so KSR was looking at the children around him, imagining what they would be like in this future he was writing.

      I don't see much hype for Mars lately, but it seems as though there was some intense interest in Mars for the past two decades. After reading the Mars trilogy, I felt like all the Mars One hype had just been people reading the Mars Trilogy and saying, "That's a good idea, let's do that!"

      I liked all the books, but the martian geology (areology) in Red Mars was written so well, I often wondered if KSR had actually been there to see it himself. The part that was really strange was that he wrote this before we got all these high-resolution, color images from Mars. The best we had was the black and white images from the Viking Lander. Somehow, KSR wrote with such detail about Mars that it was as though he must have seen it with his own eyes.

      I spent so much time with those books that the characters feel like friends that I have neglected to keep in touch with.

    It may be useful to more closely define exactly what you mean by hard science fiction. Generally, that means real science in a fictional narrative, but what I have learned is that it comes with expectations of what kind of science. And by that, I mean physics.

    A number of years ago in Hollywood my producing partner was the creator and showrunner for the SyFy show Eureka. After a few seasons he asked if I wanted to contribute a script. So I looked at what the show had done so far and thought a story arc about biological immortality would be cool.

    They rejected it. They said it didn’t have any science in it. And by that, I realized they meant the Hollywood version of science with lasers and explosions. Biology and Medicine don’t qualify.

    But if they do qualify for you, you might want to consider Darwin‘s Radio by Greg Bear. Genetic artifacts are hidden in our chromosomes and humanity stands at the cusp of radical transformation. We were developing it as a TV series when he passed. That would’ve been a great opportunity.

      Good point. What I particularly appreciate in science fiction is when authors incorporate cutting-edge scientific theories as foundational elements of their storytelling. The most compelling hard sci-fi doesn't just use science as window dressing, but explores how technological advances fundamentally reshape human society and consciousness. So it is definitely not about space pirates.

      Peter Watts's Blindsight (and notes at the end of the book specifically) exemplifies this approach brilliantly. His extensive research into evolutionary biology and neuroscience to develop the vampire subspecies demonstrates the level of scientific rigor I seek in hard sci-fi. While the technical details of the vampire biology may be complex, the way he weaves this scientific framework into the larger narrative about consciousness and intelligence is masterful.

      The book you mention is quite intriguing, thank you. I'll try to find it.

        We were all in a little hotel room in San Jose and Greg was surrounded by gadflies. I had done some close reading of recent genetic advances that I thought didn’t quite square with what he had written in Darwin‘s Radio a decade before, but it just wasn’t the time or place to get into a detailed discussion.

        He was quite nice and seemed excited about the project. Too bad the success rate in Hollywood is so low and we were not able to get any momentum before he fell ill.

Admittedly my interest ran dry as I realized (1) space communism is portrayed as bad, actually, and (2) David Weber hits the same story beats a fair bit.

      It still holds a special place in my heart, though, and I’m still disappointed there’s no game adaptation.

      (edit) also I’d put it as a ricotta on the cheese sci-fi hardness scale, so very far away from a sibling to Blindsight in that sense. Still quite fun though!

    I think you'd enjoy Pandora's Planet and Judas Unchained, a duology about humanity in the future, the Commonwealth, building its first spaceship after centuries of relying on wormholes to connect planets in a vast intragalactic network transited by trains. They're there to explore an ancient artefact, an entire planet sealed off by an alien forcefield that's recently dropped, in their first ever encounter with alien life. Points in its favour:

    • Heavy world building of the Commonwealth, its government, and the individual planetary societies some characters come from. It's beneficial but imperfect, and there are even terrorist organisations that form based on that imperfection;
    • Exploration of how transhuman augmentations have changed society - everyone is technically immortal, insured against death with implants that both connect to the internet and back up their personalities and memories, so biodeath is not (usually) permanent.
    • The alien species has a lot of world building too, with an entire condensed history of technological development from their equivalent of the Jurassic Period all the way to today, and the social interactions between each other that form how they see the world.

The Void trilogy had some interesting stuff going on with the development of the world, the ones after that I haven't read yet.

      I think he does a great job bringing the Opera back to Space Opera but understand the criticism that the cast is large enough that it can take awhile to circle back to what a given character is doing.

    The Lost Fleet series are definitely more "B-movie" sci-fi, at least plot wise, but I appreciate the amount of thought put into "fleet battles when you have to account for speed-of-light delay are really hard".

      I felt Three Body Problem had a common issue in scifi where the author feels compelled to pick the most futuristic solution to a problem and handwaving away conventional ones.

      Three Body Problem ship cheesewire event spoiler In this case, there's a bunch of terrorists on a cruise ship passing through a canal and the government needs to recover sensitive intel from their computer without giving them a chance to delete it. They settle on using carbon nano filament to cut the ship and everyone in it up into itty-bitty slices as it passes, but this has the fairly obvious drawback of also cutting through and destroying any hard drives and electronics on the ship that are at the wrong height, too, and no-one brings it up. Even just cutting through the power system could destroy the data if they're paranoid enough to put it on volatile memory, so it's lost when the power goes out. It's presented as an incredibly simple solution and all others are dismissed as "they could have prepared for that and given themselves enough time to delete the data."

        I read this one last year, and it was actually addressed in the book. They said they could fix any damage caused from clean cuts, whereas other forms of damage would be harder to recover from (missiles, fire, or intentional sabotage). There was basically a whole chapter dedicated to evaluating different approaches to taking the data safely.

      Thank you! I've read all the books in the series, and I think that the most interesting idea to me, the "Dark Forest" paradox, was in the last book.

      I feel that the writing style of Three Body Problem is more similar to the science fiction of classic American authors of the twentieth century. It has less focus on science and more emphasis on exploring human behavior in unusual settings. While the writing style might feel somewhat simplistic at times, the ideas presented are intriguing.

      So I loved snow crash but not sure I’d say it’s hard sci fi. For every thing that was either based in current reality or very prescient with its predictions of the use of that tech, there’s a lot of just flat out weird/wrong/whatever. Mostly in the service is satire or flat out fantasy I’d say.

        Are you saying that accuracy is a criteria for hard sci fi? I'm not sure how that would work when we're talking about hypothetical futures. I suppose if you mean that you didn't find it believable, then maybe we can just chalk it up to differences of opinion.

        Personally, I'd say the technology described was advanced but in the realm of possibility, and well justified in the context of advances in computing and biotech described within the universe of the story.

          I hope I'm not getting this wrong, but i remember something where there was like 3rd world sweat shops full of people playing World of Warcraft earning fake gold to sell for real money to players in richer countries. And he was like "for everything I managed to get right about the future, this is something I never would have imagined."

    Stephen Baxter is the hardest lay-readable sci-fi I know of. Greg Egan is (much) harder but his books require explanatory lectures and relatively deep knowledge of fairly obscure topics. I find them very hard going a lot of the time but he does have some interesting ideas. Baxter is a better writer in terms of being able to structure a story, imo. Start with the Xeelee sequence, but it's all good.

    If you define hard sci fi as basically not involving entirely magical explanations for stuff then the recommend list broadens somewhat. Peter F Hamilton is always worth a look. Neal Asher is good (his earlier things lean a bit more biological, like Watts). Asher's Cowl is one of the better time travel stories I know of and time travel is tough to do "hard" . Alistair Reynolds has already been mentioned and is very good. Adrian Tsaikovsky is great - start with Children of Time, it's one of my all time favourite books of any genre.

    There's also always the classics. Arthur C Clarke. Larry Niven. Poul Anderson. Heinlein I think is overrated and his politics are not to my taste, but lots of people do get on with his stuff. Asimov is a great ideas guy but dreadfully dry to read. Good for short stories if you like short stories.

    I'm not sure Iain M Banks qualifies as hard sci-fi, although he may, but his Culture series is superb and I will always recommend it. In the same vein anything by Ann Leckie.

        With Peter Watts, I'm never really sure I understand what's going on. But that makes it great re-reading material. I've read Blindsight at at least four times and there are still details I don't get.

    I haven't seen Lem mentioned on here, so I'll recommend *His Master's Voice". If you want a description of how a radical new technology can alter society, this book isn't it. Rather, Lem imagines signal encoded by a distant, unimaginably advanced civilization. Alas, Lem shows how our own civilization is not transformed by this message from the stars, only revealed. Such a brilliant book.

    Not 100% sure if it'll land for you but give Terra Ignota by Ada Palmer a try, it's near-future science fiction and a bit more science fantasy than science fiction but it's definitely a blend of the author's ideas and fiction a la Methods of Rationality. As a warning the first couple chapters open with the most magic that the entire series of 4 books has, it's way more grounded in realism after that.

    Citizen Sleeper touches upon multiple topics very well. If you don't mind the format. While not revolutionary in any sense, it's still an awesome read.

    But nothing beats Summa Technologiae for me. It just goes through everything. Accelerando spins the big game as a wild party, which is kinda fun, but Lem is slow and methodical as he completely obliterates any and all mysteries, leaving us with simple existential dread and clear choices. Where Accelerando tells us "it's gonna be fine, live up a little", Lem shrugs and leaves us with simple "it's up to us, let's not be idiots".

    I still have this cool little video inspired by Golem XIV up, that I've reuploaded without permission many years ago. Give it a watch to get a taste.

    One book I rarely see mentioned but really enjoyed is The Forever War by Joe Haldeman. If aliens take it out of the running, it's out, but what it does really well is the repercussions of slower than light travel and relativistic time.

    The wiki entry for this book links to SF Masterworks, there are some great classics on that list. You can go to the overviews to see if you think you might like any.

    For works on that list you may have preconceptions about:

    • All the movie adaptations of I am Legend are terrible. Matheson actually had his name taken off The Last Man on Earth.
    • Do Androids Dream of Electric Sheep is only like Bladerunner in general theme.

    I haven't seen it mentioned yet, but I enjoyed the books I read from Charles E Gannon. I read up through Marque of Caine in his bibliography and although the books are definitely more in the thriller vein (think Crichton and the like) they do have a pretty rigorous hard Sci fi bent to them. At least at one point the first book in the series was a free ebook download but I'm not sure if it still is.
