Generally-speaking, science-fiction is a genre where authors are allowed to virtually take as many liberties as they want in regards to realism without adverse consequences, so long as they do it correctly of course. This makes sense, too: most authors aren’t well-versed in scientific fields, and studying them would take years which many people simply don’t have.
As such, we’ve come to accept most science-fiction novels as being relatively close to fantasy, and we inherently accept to suspend our disbelief when we choose to read them.
This has been the way until 1957 when John W. Campbell published Islands of Space. The term “hard science-fiction” was used to describe it in a review by P. Schuyler Miller, and things were never the same again.
Hard science-fiction novels make one of their primary concerns the maintenance of scientific accuracy and logic, no matter how futuristic or improbably any society or piece of technology might be. These novels lay a groundwork of hard realism to support their fantasy, to the point where they can feel as real and plausible as an actual peer-reviewed study.
Here you will find all types of hard science-fiction novels, from the classics of a few decades ago to modern bestsellers, as I try to single out the ones which really achieve an excellent balance between scientific accuracy, thought-provoking ideas, and relatable entertainment.

“Foundation” by Isaac Asimov – Dying of the Scientific Light
Isaac Asimov has exerted a nearly incalculable influence on the genre of science-fiction with the publication of his Foundation series, still discussed to this very day.
In the first novel, simply titled Foundation, we witness the start of humanity’s collapse into barbarism and intellectual devolution, and one man’s ambitious plan to restore it back on the right track and preserve its incredibly advanced scientific knowledge.

“Foundation and Empire” by Isaac Asimov – The Unpredictable Factor
Isaac Asimov has forever changed the landscape of science-fiction with the Foundation trilogy, tracing the attempt of relatively few humans to shorten an impending dark age of barbarism down to a thousand years.

“Quantum Space” by Douglas Phillips – Lost in a Space Limbo
Despite having technically been in front of our eyes since our existence, the realm of particle physics still holds a vast and seemingly endless ocean of secrets from us.

“Quantum Void” by Douglas Phillips – Leaping into the Uncharted Cosmos
Douglas Phillips began his unusual and highly-captivating exploration of quantum physics and space travel with the aptly-named Quantum Series, and in the second book, titled Quantum Void, he takes things one-step further.
With the recent discovery allowing to compress space, intergalactic travel has been opened up to infinite possibilities, and the humanity is preparing to send six envoys to an alien civilization light-years away.

“Quantum Time” by Douglas Phillips – An Extra-dimensional Journey
Douglas Phillips has explored some of the more interesting frontiers of our knowledge in his Quantum Series, and in the third book, titled Quantum Time, we join Daniel Rice, a time traveller on a mission to stop a nuclear holocaust.
After a dying man stumbles into a police station claiming to be from the future, a series of predictions come true, and it becomes clear the Earth is on the verge of truly unexpected peril

“Cold Storage” by David Koepp – One Night to Extinction
David Koepp has taken a long time to transpose his screenwriter’s talents into the form of a novel, but in 2019 he finally did so with his first published work of fiction, Cold Storage.
It tells the story of Roberto Diaz who once managed to contain an organism capable of causing a total extinction of humanity.
Decades later, the organism has found its way out of containment, and the old Diaz has only the night to try and contain it, with his help being two unwitting security guards.

“Recursion” by Blake Crouch – Memory Shapes Collective Reality
Blake Crouch has shown a remarkable ability to put humanity into inconceivable scenarios, and in Recursion he does so once again, pitting it against a nigh-incomprehensible invader.
The story follows Barry Sutton, a New York cop tasked with investigating False Memory Syndrome, an affliction driving people mad with the memories of others.
Digging deeper, however, only brings him closer to a nearly-undetectable invader, dead-set on tearing apart the fabric of the past and unmaking the world.

“Children of Time” by Adrian Tchaikovsky – Heirs to Humanity’s New Eden
Adrian Tchaikovsky has for a long time been a prominent figure in the realm of science-fiction literature, and for many the pinnacle of his work, so far at least, can be found in Children of Time, winner of the 2016 Arthur C. Clarke Award.
It tells the story of humanity’s last remnants as they leave a dying Earth in search of a new home. The new planet they find is perfect at first sight, but hope quickly turns to despair as the lethal dangers of the unknown world begin rising to the surface.

“Sekret Machines Book 1: Chasing Shadows” by Tom DeLonge and A. J. Hartley – The Truth is Out There
Tom DeLonge and Andrew James Hartley have achieved quite a bit of success in their own respective fields, and thus their collaboration in writing Chasing Shadows was an intriguing turn of events to say the least.
In it, we are told the story of four different people who find themselves on a collision course with otherworldly alien technology.
Each one of them will have to make hefty choices in the face of powers which could either change the course of human history for the best, or wipe it off the face of the galaxy.

“Sekret Machines Book 2: A Fire Within” by Tom DeLonge and AJ Hartley – Saga of Cosmic Solitude

Now bonded by what they have all witnessed, they find themselves hunted by the ruthless black suits.
While Alan and Barry test the limits of their powers in a military complex, Jennifer and Timika go on a quest for a tablet which may hold many more answers than humanity ever bargained for.

Ball Lightning” by Cixin Liu – Dangerous Frontiers of Science
Cixin Liu has broken many frontiers in international science-fiction with his highly-acclaimed Three-Body Problem trilogy, and it seems the rest of the world couldn’t get enough as another one of his inventive novels received a translation, titled Ball Lightning.
In it, we follow the story of a young man who devotes his life to deciphering the unnatural phenomenon which took the life of his parents, the titular ball lightning.
His search, however, takes him to an entirely new frontier where generals, physicists and madmen pursue scientific discovery, no matter the cost.

“The Freeze-Frame Revolution” by Peter Watts – An Impossible Rebellion
Peter Watts has won a number of awards for his tremendously original science-fiction stories, and few exhibit this quality with the same aplomb as his novel The Freeze-Frame Revolution.
It follows a protagonist trapped on a starship with the intent of creating a massive human uprising.
The only problems? He’s only awake one day out of a million, his potential allies keep changing from one shift to the next, and he’s facing an enemy who never sleeps, can see and hear everything.
Is a successful revolution even possible under these circumstances, or is it yet another pipe dream for desperate humans?
