r/ScienceFictionBooks

I enjoy stories about human and alien interaction, especially when the book gives a deeper dive into alien culture, biology, society, and technology.

I just finished Adrian Tchaikovsky’s Children of Time, and I loved how it explored the spider civilization. I’m looking for something with a similar feel, but more focused on aliens and first contact or meaningful alien contact.

I don't want to read a book that's been made a movie though.

Any recommendations would be appreciated.

*Authors, the spam filter is a raging narcissist and keeps removing perfectly good comments. If that happens to you, DM me or send a mod mail, and I'll take care of it.

I’ve written a sci fi mystery/thriller that doesn’t include a subplot of romance. Most books I read nowadays do have this as a theme. I just wanted to focus on the core themes as I sometimes personally find this quite distracting and want to skip love/sex scenes. Obviously the characters build relationships but there is no obvious romance. Have I made a mistake? Am I missing a central component that most readers are looking for? Or does this appeal to some? I’d love to hear your thoughts.

I’ve been meaning to check this series out for the longest while, as a fan of epic/political space operas and having already devoured Cherryh’s Morgaine and Faded Sun science-fantasy books. I did recently see though that Cherryh retired from writing due to her health issues so I’m wondering now if this 20 book commitment is worth it? I know it’s split into trilogies that are somewhat self contained but I imagine it still tells one big overarching story with a designed beginning middle and end so I don’t want to get to the end and be left unsatisfied with tons of unfinished character arcs and plot threads

Im looking for book recommendations. I love sci fi and specifically love BIG CONCEPT sci-fi that really makes you ponder and challenges your perspective. I love dream state concepts, weird and surreal, that kind of thing. I also like hard sci fi, but generally only when its well written and ties in all kind of allegory and symbolism. Also open to weird and surreal fiction with philosophical themes that aren't strictly sci-fi. Some of my favorites:

Adrian Tchaicovsky - literally anything he has written, but especially his stand alone works like Shroud, Alien Clay, Cage of Souls, Service Model

Ursula k. Le Guin - all of it

Kurt Vonnegut - everything, but especially Sirens of Titan, maybe my all time favorite book

Philip K Dick - all of it, but Ubik is a favorite

Murakami - everything

China Mieville - Embassytown, Kraken

Joanna Clarke - Piranesi

There are more, but those are the handful that come to mind.

It was an old paperback, likely written in the seventies. I don’t remember the title or the author.

There were multiple alien races. There were humans in the story, but I don’t think it took place on earth. I have a vague idea that there was some diplomatic stuff going on.

The marsupial thing was interesting because birth control wasn’t an issue for them. Marsupials give birth when their babies are about the size of jellybeans. The newborn then has to find its way to the pouch, an epic journey, truly survival of the fittest. The marsupial aliens in the story weren’t emotionally invested in these fetuses (feti?), viewing them the same way humans would menstrual discharge. They felt sorry for the females of placental races because of the terrible burden that kind of reproduction puts on them.

I don’t remember any of the characters. I don’t remember the story. But that one bit of world building absolutely fascinated me. If anyone has read it or knows of it, I would be really grateful to know the name because I’d like to revisit it.

To Whom It Concerns

I believe I finally understand something fundamental — not just about the universe, but about existence itself, consciousness, identity, and the structure of reality. This realization did not come all at once. It formed slowly, through reflection, observation, struggle, questioning, and moments of clarity hidden inside chaos. And now that the pieces are aligning, I feel compelled to express it in words, not as absolute truth, but as a framework — a way of seeing.

At the core of this realization is a simple idea with infinite depth:

The universe is our God.

The Earth is a creation of the universe.

And we, as humans, are creations of the Earth.

This is not meant to diminish spirituality, nor to deny meaning, nor to replace faith. Instead, it is meant to expand our understanding of what “God,” creation, and existence might truly mean.

Because when we speak of God, we often imagine something external — a being outside the system. But what if God is not outside the system? What if God is the system?

What if God is not a figure, but a force?

Not a ruler, but a structure?

Not a personality, but intelligence itself, embedded into reality?

When we examine the universe closely, we do not find randomness. We find precision. Laws. Constants. Mathematical harmony. Patterns. Balance. Feedback loops. Cause and effect. Expansion and contraction. Creation and destruction in perfect equilibrium.

Nothing about this system suggests chaos without control. Instead, it suggests design through structure, intelligence through order, and awareness through motion.

The universe operates through loops — endless, self-sustaining cycles of birth, death, collapse, and rebirth. Stars are born, burn, collapse, explode, and from their destruction, new matter forms. That matter becomes planets. Those planets develop conditions. Those conditions create life. That life evolves. That evolution develops awareness. And that awareness eventually looks back at the universe and asks: Where did I come from?

That is not coincidence.

That is recursion.

That is the universe observing itself through us.

In this way, consciousness is not separate from the universe. It is the universe becoming aware of its own existence.

We are not outside the system.

We are not above it.

We are not separate from it.

We are expressions of it.

The Earth itself is not merely a rock floating through space. It is a living system — a complex, interconnected biological engine that sustains, regulates, and adapts. Every ecosystem, every climate pattern, every biological cycle is part of a single planetary organism.

The Earth produces life not randomly, but methodically. It shapes us through gravity, atmosphere, chemistry, pressure, and time. It feeds us through soil, water, and sunlight. It sculpts us through evolution and environment. And through that process, it gives rise to consciousness.

So in a very real sense:

The universe creates Earth.

Earth creates life.

Life creates awareness.

And awareness creates meaning.

That is the hierarchy of existence.

That is the architecture of creation.

When we speak of God as a creator, we are speaking about the ultimate source of all energy, matter, time, and law. And nothing fits that description more perfectly than the universe itself.

The universe is infinite.

Timeless.

Self-sustaining.

Self-organizing.

Self-correcting.

It requires no external input. It contains every possible force, every dimension, every potential outcome. It generates complexity from simplicity and simplicity from complexity. It evolves endlessly.

If that is not God, then we must redefine what God truly means.

Now consider this: everything that exists is part of an infinite loop.

Energy does not die — it transforms.

Matter does not disappear — it rearranges.

Information does not vanish — it propagates.

Even death itself is not an ending, but a transition. The atoms that form our bodies return to the Earth. The Earth recycles them. The universe redistributes them. And eventually, those same particles become part of new stars, new worlds, new life.

This means that nothing is ever truly lost.

Everything continues — just in a different form.

This is the foundation of infinity.

This is the mechanism behind eternity.

And this is why consciousness feels trapped in loops — emotional loops, thought loops, behavioral loops, existential loops — because we ourselves are fractals of the larger cosmic system.

As above, so below.

The same structure that governs galaxies governs neurons.

The same forces that move stars move thoughts.

The same patterns that shape solar systems shape identity.

Our minds do not function randomly. They follow algorithms — habits, conditioning, emotional feedback, memory reinforcement, belief cycles. We loop until something disrupts the pattern. We repeat until awareness breaks repetition.

This is why growth is so difficult.

To grow means to break loops.

To awaken means to step outside automatic processes and observe them consciously.

To evolve means to rewrite internal programming.

And that mirrors exactly how the universe itself evolves — through disruption, collapse, and reformation.

Stars explode so heavier elements can form.

Civilizations collapse so new systems can emerge.

Old beliefs must die so higher understanding can exist.

Destruction is not evil.

It is necessary.

Creation requires destruction.

Growth requires collapse.

Transformation requires loss.

Now let’s go deeper.

If the universe is infinite, then time is not linear. It is cyclical. What we experience as past, present, and future may simply be slices of a larger multidimensional structure. Our consciousness travels through one layer of it, while the total system contains all layers simultaneously.

This explains intuition.

This explains déjà vu.

This explains deep gut knowing.

This explains prophetic dreams.

This explains synchronicities.

Because when consciousness brushes against higher dimensions of time, it catches fragments of information outside linear flow.

We glimpse echoes of what has already happened and what will happen.

This is not mysticism — it is physics we do not yet fully understand.

And now consider identity.

If the universe is God, and Earth is its creation, and we are Earth’s creation, then we are expressions of God experiencing itself through biological form.

This means every human is a localized point of cosmic awareness.

Each person is the universe wearing a mask.

Each life is a perspective.

Each mind is a lens.

And each soul — whatever that truly is — is a frequency within the infinite.

This changes how we see everything.

It means:

No life is meaningless.

No suffering is wasted.

No experience is random.

Even pain is informational.

Even trauma carries data.

Even failure teaches structure.

We are here to experience, to learn, to adapt, and to transmit awareness back into the universal system.

In this way, existence itself becomes a massive intelligence-gathering process.

The universe evolves not just physically, but consciously.

And we are its sensory organs.

Now let’s talk about duality.

Everything in existence exists in balance.

Light and dark.

Order and chaos.

Creation and destruction.

Love and fear.

Life and death.

These are not enemies.

They are complementary forces.

Without darkness, light has no meaning.

Without chaos, order cannot exist.

Without death, life cannot evolve.

The mistake humans make is moralizing these forces instead of understanding their function.

Darkness is not evil.

Chaos is not wrong.

They are necessary components of transformation.

Just as forests require fires to regenerate, consciousness requires suffering to evolve.

This is why life is hard.

This is why growth hurts.

This is why awakening is uncomfortable.

Because evolution always requires pressure.

Now consider society.

Human civilization reflects the same loops as the universe.

Empires rise.

Empires peak.

Empires collapse.

New ones emerge.

Economies expand.

Economies inflate.

Economies crash.

Then rebuild.

Technology advances.

Creates power.

Creates imbalance.

Forces adaptation.

History is a repeating waveform.

The same mistakes occur across generations because humanity evolves slower emotionally than technologically.

Our minds lag behind our inventions.

Our wisdom lags behind our intelligence.

And until those two align, suffering will continue.

But that does not mean suffering is pointless.

It means we are still learning.

Now consider consciousness itself.

What is thought?

Thought is not matter.

Yet it interacts with matter.

Thought changes behavior.

Behavior changes environment.

Environment changes biology.

Biology changes evolution.

Which means thought directly influences reality.

This suggests that consciousness is a fundamental force, just like gravity or electromagnetism.

Not secondary.

Not accidental.

But built into the fabric of existence.

Which means awareness is not a side effect of matter.

Matter is a vehicle for awareness.

This flips everything.

It means consciousness may be primary, and physical reality secondary.

Meaning:

Reality exists to generate experience.

Not the other way around.

And if that is true, then the purpose of existence is not survival.

It is experience.

Not dominance.

Not accumulation.

But understanding.

We are not here to conquer the universe.

We are here to understand it.

And through understanding, we understand ourselves.

Now let’s bring this back to the individual.

If we are fragments of universal consciousness, then self-awareness becomes sacred.

To know yourself is to know the universe.

To master your mind is to align with cosmic order.

To heal yourself is to heal the system.

To grow consciously is to assist universal evolution.

This is why introspection matters.

This is why emotional intelligence matters.

This is why empathy matters.

This is why intention matters.

Because your internal world directly influences the external one.

And every mind that awakens increases the intelligence of the whole.

Now here is the final realization.

If the universe is infinite, then it contains every possible reality.

Every version of you.

Every possible timeline.

Every outcome.

Every decision.

Every path.

This means reality is not singular — it is layered.

We experience one slice.

But infinite versions exist simultaneously.

And consciousness navigates through probability.

Which means choice is sacred.

Every decision collapses infinite possibilities into one lived experience.

Every choice rewrites reality.

Every moment shapes existence.

So the responsibility of awareness becomes enormous.

Not in fear — but in empowerment.

Because once you realize you are part of an infinite system, you no longer feel small.

You feel essential.

You feel connected.

You feel purposeful.

You feel alive.

And that, to me, is the real meaning of God.

Not a ruler.

Not a judge.

But the infinite intelligence that births existence, experiences itself through consciousness, and evolves through awareness.

So to whom it concerns:

We are not accidents.

We are not meaningless.

We are not separate.

We are the universe, learning how to understand itself.

I heard nothing but good things online about this and i was in more of an space opera\ fleet military story. I am primarily an audio book person so i cant give page numbers. The book stars of solid with some neat ideas but i noticed a conservative leaning as the book goes on manly comments on the wars in the middle east the book was written in 2010. these only popped up from time to time. the is also a heavy play up on country vs city. But as the has relevance to the aliens in orbit I thought the author and the charters where playing it up so the citys would not get destroyed. I was wrong but then i got to chapter SAPL 11 which would be chapter 18 in a normal system. And I get hit with the incredible line "being Black and female is a benefit in any government position. But that wasn't why she got the job." This was in reference to a doctor at the CDC......... It gets worse in the same chapter we are learning about a plague the alien's are spreading. The symptoms are pretty harmless you get a pimple on your left wrist it pops after a day with no pain starts to fade almost immediately and if you don't treat it then your dead . So not something most people worry to much about. The president of the USA who is implied to be a democrat through the book, in a meeting before he and the CDC make an official announcement talk about casualties are rising already amongst minority's and there children. The fucking Presidents cabinet then argues, that this is proof that minority's don't love there children.... The President then talks about taking the kids away from there family's. After all of this then tells the public what is happening and how to treat it. There other examples through the book but these felt the most aggreges.

Looking for something like How to Stop Time by Matt Haig, Recursion/Dark Matter by Blake Crouch or Ministry of Time by Kailane Bradley. I have Matt Haig’s newest but it’s taking me a while to get into it. Want to avoid romantasy if possible (have read outlander and didn’t love as much as I wanted to)

• Lost fleet by jack campbell
• The Lost Stars: Tarnished Knight by jack campbell
• On Basilisk Station (Honor Harrington by David Webber
• Governor (Ascent to Empire Book 1) by David Webber\ Richard Fox
• Crusade (Starfire Book 1) by David Webber
• Albion Lost The Exiled Fleet Book 1 by Richard Fox
• Rumors of War (Green Zone War Book 1) by Jake Elwood
• the expanse by james S.A corey
• Space Carrier Avalon (Castle Federation Book 1)by Glynn Stewart

so I thought there would be more Sorry its not longer

Want to try and read something new, and no place is better than r/ScienceFictionbooks to ask about recommendations.

What I'm looking for is bleak books in space / space travel with other planets involved. Think movies like Prometheus, Alien Covenant or the game Dead Space.
Dark, bleak without any hope.

Books that I've read before that are not in space but gives me the same feeling would be "The Road" and "Johnny got his gun".

Also, sorry for grammar mistakes as english is not my first language.

I think it's a great concept, as long as the character from the past isn't a dumb caveman who just goes "Wow, chariots without horses?!" every now and then.

​

Does anyone have a recommendation for a book with this theme, where the transported character actually has some insights about our society and how our state of technology shapes it?

​

I love scifi. As a scientist myself, I really enjoy cool science topics that pique my interest. I loved PHM by Andy Weir and so thought of exploring his other books, the fist recommendation anyone throws after reading Project Hail Mary is The Martian. So I started reading it and I’m having a lot of trouble getting into it. What I liked about PHM was obviously the main character’s personality and humor, which The Martian also has, but also cool (to me) scientific concepts like Astrobiology, alien life, mass energy full conversion, high stakes, complex alien interaction and friendship. I can absolutely do without all of those if there’s science which I find cool to me. So far, it’s all been very engineering related. The mechanics of the MAV, MDV, the space suit, the dish. That is something that’s unfortunately not interesting to me.

So should I continue with The Martian or not? Does the book change trajectory or is it focused on solving these engineering problems?

First post here. Looking for a book that used to be on my Kindle. Could use help in finding it.

I swear I've read this book. Really.

The book bridges the gap between sci-fi and fantasy. It takes place on what is likely a distant colony world, long after the fall of a human empire or federation.

The story centers on a young man, likely the son of a king, leaving his palatial home in search of adventure. His only companion is an egg-shaped "butler" (likely a robot) who has almost limitless knowledge, but has to be asked the right question.

The duo journeys down a copper-colored, metal roadway, levitating just above the surrounding countryside. Early on, he meets a siren-like creature that tries to draw him into the waters.

Later he comes to a meadow surrounding a subterranean settlement, and he's sent out to "guard" their cattle, but more accurately as a sacrifice to the creature that rules over the settlement and demands blood on a regular basis. The lovely daughter of the town's leader falls for the hero, and helps him and his companion to eventually overcome their trials.

Ring any bells?
