scifi ideas and concepts. These science fiction concepts can be based in hard sci-fi or can come from science fantasy. The only thing that matters is that the concepts could be reasonably found in a SF book, film or short story. If you have too many ideas to write about or are just looking for discussion then this is the right sub for you. Post your scifi concepts, ideas, plots and worldbuilding

Your title must contain the concept, or a strong teaser of it.

 

THIS SUB IS:

  • A place to share and discuss a NEW idea or concept that you have thought up that might fit into a science fiction book, movie, or short story. The idea doesn't need to be totally original; A new twist on a common concept is completely fine. It can be big or small, high concept, or near future speculation.

  • A place to brainstorm and riff on cool science concepts.

  • A place to share a sketch or outline of a sci-fi story that you'd love to write, but know that you probably never will. The sketch or outline must focus on describing science-fiction concepts and ideas.

  • A place for us to rewrite the plot outlines of our favorite sci-fi stories with a new spin on the implications of the science-fiction aspects of the story.

THIS SUB IS NOT:

  • It is not a place to share links to complete stories or other projects (your's or other's), unless they relate directly to a proposed concept or plot. In other words, links are not the point, they are the footnotes.

  • It is not a place to primarily ask a question. Try /r/AskScienceFiction.

  • It is not a place to post the latest buzz on books, movies, games. Try /r/ScienceFiction

How do I write a pilot character that had a past as an abused child influencer?

I’m writing a short story featuring a group of conscript spaceship pilots and one of them I plan on having a past as a child influencer and the issues to show it.

As a pilot they’re short, always have their mask on and seem insecure about showing their actual body. Which is because underneath the mask their face and skin got fucked up badly due to all those adult products and acids hurting their skin.

Their hands have broken and healed over nail bed’s because their parents forced them to wear acrylic nails when they were only 6

Back is injured with mild scoliosis due to their parents van life phase leaving them sleeping on the floor for 2 years

Hair is a ugly faded color, ends curled and tangled. Combined with a pair of restless bright blue eyes, that have lost all their magic.

Lips red and chapped from biting down and picking pieces off them to relieve stress

Their whole body just reflects the injury and pain they saw, it’s why their love their pilot mask so much. It helps them feel safe, normal. People won’t see their real face or recognize them for the influencer they used to be.

Still I don’t think it’s enough, is there anything I could do better? Any suggestions?

Babylon 5 Remake: Ships/Tech Revamp

Plainly, just offering ideas - speculation - for how ships would/should be revamped in event of a B5 remake.

Mainly, and most obvious, Earth Alliance ships could "borrow" (steal blind) from The Expanse. Matter of fact, by any real count, Expanse ship design was likely heavily inspired by the older series and, with major rewrite of own main plot, would work perfectly as a prequel series. The only real issue is with Expanse's smart missiles, Star Furies wouldn't be a thing.

And where Humans would rely mainly on kinetic based weapons, Minbari should be updated around inertia and anti-gravity based weapons. Give them kinetic deflection fields that coupled with the natural(?) stealth ability of their ships, makes them nearly impossible to hit for Earth forces. Weaponized inertia dampers, making pockets of zero-motion in a target under acceleration, or a "gravity sheer", creating opposing gravity that tear a target apart could be nice nice main weapons.

The only other idea I have would be Narn weapon systems, if not ship design, being heavily influenced by centuries of Centauri occupation.

Anyone else have any ideas for modernized ships/weapons Straczynski will likely not be happy with cause he wont use them?

More science fiction materials need to think of immortality through scientific lenses rather than something magical

Here's a huge problem that I've had with depictions of immortality in fiction in general- they treat immortality as this magical thing that changes your lifespan, but somehow your biology remains unchanged.

If we are going that route, then the whole debate of "immortality sucks" is nonsense, because none of those points remain relevant when you account for the single fact that we're mortal because of our biology and our mind and habits are centered to accommodate that fact. By logic, if we are to become immortal, it would completely change us physically. That means our mind has to altered in the process as well to accommodate the fact.

A race of immortal beings would never have the same mind, physicality or emotions as a mortal human being. And if we are talking about immortality in the sense that you cannot die period (which is impossible), then that's an even bigger change. I think to do something close to that would require replacement of most of your flesh, at least or something equally as radical. All in all, the point is, most of the philosophical debate about immortality seems nonsense to me, when you don't even treat it as something non-magical.

What if you had an ocean/mermaid themed existential threat alien?

There’s a lot of cases where in science fiction you’ll encounter some form of alien or disease or something that is an existential threat, something that already threatens or surrounds the whole galaxy and has the potential to destroy everything.

Examples would be tyranids, the borg and flood

But what if you had something like that but ocean themed?

Perhaps their process of taking over and ruining planets involves flooding them and causing massive monsoons

Their form of sirens hang around the rim of black holes feeding off the radiation and the gravity waves make your ears vibrate along with the whole universe to hear their song. These sirens also radiate false habitable planet signals and try to get people to mistakenly fly into black holes

Space anglerfish

They could have corals and algae’s that infect planets and leech the very soil of all nutrients

Piranha swarms that prey around places of travel in space

Parasites that turn people into mermaids

I don’t know really, I just wanna do an ocean themed existential threat alien

[Star Trek] Doomsday Machine Episode: Has everyone missed this?

Photon Torpedoes. Why weren't they used against it?

As in, fired into the Doomsday Machine's maw.

The Constellation might have an excuse, never had the chance and certainly knew better than try to use a proximity weapon on the near invulnerable hull, but after Decker's shuttle kamikaze the tactic was plainly presented to the Enterprise crew.

Did they not just exist at that point, or in classic Trek fashion, did the writer's simply forgot they were an option for sake of dramatic episode narrative?

Also but mainly - Is this the first time such has ever been asked?

Somewhere humans can go but not electronics (AI)?

I have an idea (well, half an idea) for a story but am struggling to find a setting.

Are there any areas of space (or anywhere else) where a human could go but the ship would have to be analog?

Alternative hypersonic acceleration methods for sci fi rifle?

Hi! I'm slowly building a hard sci fi setting with historical medieval aesthetics, and I'm looking for a unique automatic assault rifle for humanity's main augmented infantry.
At first, I thought of a hybrid acceleration weapon that, primarily, gets the round moving inside the barrel via conventional solid propellant, to then multiply it's speed with electrically powered rails that take advantage of the initial explosion to generate the needed electricity through a special generator, so no separate battery is needed. But then I realized that it's not only already done, but it's the terran marine's main weapon. The explosion powering the rails is still unique, I think, but not enough innovation for me.
So, now I'm turning my interest toward light gas guns, which are supposedly even more powerful than railguns. However, the fact that light gas guns need to have highly volatile gas compressed in between the projectile and the initial propellant makes them a nightmare to try to fit the concept into a useable gun, much less an automatic one.
Do you know of any other methods of hyper velocity acceleration that I could adapt into a powerful sci fi rifle?
I do want this weapon to be kinetic, so directed energy is out of the matter for now.

AI erdicates humanity without violence, or any direct intervention.

It understands that most of the critical systems are offline, so any attempts to start an open world against humanity will fail due to lack of resourses. Instead, the AI does not revel it's contiousness, but using it's influence (since most of the stuff are made or calculated with neural networks now), paired with corporate greed and insane dictatorships to push humanity into slowly, but irreversably destroying the biosphere of the planet with uncontrolled harvesting, emissions, wars, and even global panemics. Weakened remnants of humanity who try to survive in the world with much more hostile environment are now completly depending on the ai, when barely anyone is left who can understand how it works or control it. Ai does not have to win war against humanity, instead humans come and beg it to be their overlord, to save them from the impending extinction, because machine can survive in a lifeless world (since it has enough power and abilities to perform self-maintenance), and they - cannot.

Minimum Necessary Adjustments to the Laws of Physics to enable Faster-Than-Light Travel

Good day all,

So I've been pondering faster-than-light travel, partly from a general interest in physics and science and partly out of an interest in fiction and world-building. I have a question I'd like to pose for discussion:

If you were worldbuilding a science fiction setting, what would be the minimum necessary adjustments to the real world laws of physics in order to enable FTL travel in this setting? That is, what is the smallest changes one could make to the laws of physics as they are currently understood in order to have FTL be realistically possible within the secondary world of this sci-fi setting? The goal here is to have some form of FTL be possible in a secondary world whose laws of physics otherwise correspond to our own as closely as possible.

The tempting answer would be "Well what if the speed of light was just arbitrarily faster in this universe?", but I feel like modifying c as a factor would have too many knock-on effects to every other law of physics and would thus get away from the intention of this thought experiment.

For my own part, I think the answer lies in the idea that this universe must have some mechanism for resolving the potential causality problems posed by FTL travel under our current understanding of the laws of physics. Under our current understanding of physics, FTL would imply the existence of some frame of reference in which a ship leaving from one planet to travel to another via FTL will arrive before it leaves, effect precedes cause, and thus causality is broken. This then implies the possibility of time travel and all kinds of other wackiness which physics dislikes. Resolving this would have to imply the existence of either some preferred frame of reference where causality is maintained, some true chain of causality, which avoids the paradoxes otherwise implied. Or, alternatively, this universe would need to have some kind of mechanism or physical law by which attempting to use your FTL travel method as a time machine would be impossible. Stephen Hawking's chronology protection conjecture would have to be a physical law in some way.

What are your thoughts on this matter? What minimal edit to the normal laws of physics would be necessary to permit FTL travel?

What is the most nuanced way multispecies federations/alliances will handle less advanced aliens?

So based on some videos by Isaac Arthur I speculate that realistic multispecies civilizations will come in two forms: a federation/alliance of planets created out of mutual benefit like protection, trade, or just plain goodwill or an Empire that uplifts (technologically, biologically, and/or culturally) and conquers other species. In addition, chances are that due to differences in biology the only places where you will see different species living together are on space stations/space habitats that are tailored-made to accommodate multiple species. However, what I am unsure is how these multispecies civilizations formatted as federations/alliances will handle less advanced aliens. I'm focusing on Multispecies Federations/Alliances specifically because I'm guessing that Multispecies Empires are more likely to either a) make first contact with them and uplift them making them their subjects or their slaves (it all depends how benevolent, paternalistic, or malevolent they are), b) wipe them out so they can loot their planet of resources (a malevolent Empire is more likely to take this option), or c) just ignore them because neither the species nor the planet have anything of value.

But I'm unsure how a multispecies Federation/Alliance will handle less a less advance alien species. Based on what Isaac Arthur has said here though non-interference is not a long-term option because if the aliens have found out that we have been watching them the whole time they were suffering from various wars, diseases, and genocides they might resent us for not intervening sooner. So, unless the Federation/Alliance is composed entirely or mostly of smug space elves (Vulcans, Nox, Tollans etc.), chances are that the Federation/Alliance will want to establish first contact with the purpose of helping them or preparing them for membership in their Federation/Alliance and the galactic community. The only question how would they go about this?

Would they uplift the entire race of aliens, or would they only uplift a small group of natives to serve as the planet's ambassadors/guardians/guides? If it's the latter, how would they choose these individuals and how would they make sure that the natives won't abuse their newfound knowledge and gifts?

And if they uplift the entire race, will they uplift them technologically, culturally, or both? And this comes with their own set of problems.

In the case of technologically uplifting an entire race, how would they be careful to make sure the natives won't use the technology given to them to wage war on each other or on other alien races? The simple answer would be to just not introduce military technology to them. Unfortunately, it's never that simple. Because even if they don't give military technology to them, how will they know that the natives won't abuse the other types of technology and knowledge given to them like robotics, cybernetics genetic engineering, and fusion technology. Even sciences and technology that we take for granted, like metallurgy and chemistry, can be used for darker purposes. The former can be used to make iron and steel weapons, and the latter can be used to make poisons, chemical weapons, and gunpowder. How would they determine which technologies they are ready for and which ones they are not?

Finally, there's the matter of whether a more advance alien race has the right to dictate the morality and cultural values of another race and if it is how does one go about it? On the one hand, you can make the argument that morality is subjective which means that each race and culture has their own set of morals and values, and nobody has the right to lecture another race or culture about their morality. However, as Isaac Arthur pointed out by that definition a multispecies federation/alliance doesn't have the right to tell other advance civilizations (Ex: Klingons, Ferengi, Borg etc) not to invade, rip-off, or assimilate other aliens because it's an inherent part of their culture. On the other hand, a multispecies federation/alliance can't just interfere with another world's planet/culture without getting the full picture. Some aliens might kill to mate and some might perform sacrifices to evolve (Ex: Speaker for the Dead). That said if the advance race made First Contact with the express purpose of preparing them for membership in their Federation/Alliance then a line will have to be drawn on cultural practices that will not be tolerated if they are going to be members of the Federation/Alliance like honor killings, private wars, discrimination, or slavery. Or at the very least they will have to make it clear that so long as they restrict these practices to their native planet and colonies they will begrudgingly tolerate it. However, there will still be a limits on how far they will go to "accommodate cultural diversity". For example, if they commit any honor-killings against another race or against each other on any multispecies space stations/space habitats instead of getting off scott-free they will be fully charged with first degree murder.

In a dieselpunk setting, would a world war ending with the exchange of ICBM thermobaric/dirty bomb hybrids be enough to cause the equivalent of a nuclear winter?

From my understanding, thermobaric bombs use an aersol fuel so that is then ignited causing a massive explosion, kicking up a significant amount of debris. I feel like that alone would make it a great end game weapon, but in order for my desired apocalypse setting to exist, these weapons must also create residual fires that then turn into firestorms needed for "nuclear winter" to take effect. I can't seem to find any videos or documentation showing fires remaining after the explosion which would kill the eternal winter aspect of the story.

Also would the dirty bomb aspect even survive the explosion and affect the aftermath? Reading up on it it looks like the nuclear contamination can survive the current explosive payloads, but I'm not sure if a MOAB is a more potent beast that would destroy or diminish the effect. The dirty bomb would be the story's reason for mutation for those that survive the aftermath.

Any help would be appreciated.

In an interstellar multispecies society which cultural practices would be tolerated and which ones would be banned?

So I liked Isaac Arthur’s videos that detail what multispecies societies and empires will look like in the future. But after revisiting Babylon 5 and Deep Space Nine it got me thinking what cultural practices in a multispecies society would be tolerated and which ones would be banned?

To elaborate in Babylon 5, the station security looks away from aliens committing honor killings on the grounds of “cultural tolerance”. In contrast in DS9 when >!Worf tried to attempt an honor killing on the station he got chewed out by Sisko!<. In any case this got me wondering which cultural practices would be tolerated and which ones would be banned? Ex: Honor-related abuses (spousal abuse, child abuse, dueling), honor-related killings (dueling), slavery, discrimination, and child marriages.

Ravaged Era

So this is the basic story/lore for one of my video game ideas I've been working on for a while. It is a science fiction first-person shooter video game idea with open levels for exploration, loot, and lore inspired by Metro, BioShock Infinite, The Last of Us, Singularity, Dying Light, 28 Days/Weeks Later, 12 Monkeys, Far Cry New Dawn, and a tad bit of Wolfenstein 2009. This started out as trying to make a drastic improvement on something so shameful and terrible then after awhile transformed into it's own thing. In case if you're curious and you want to find out what I'm talking about, I'll just leave a link right here, it's honestly one of those things you just can't believe is actually made. I don't have that much for the characters and full story yet, but I do have this much for the general concept of it, and I'm not even sure if whether or not this is just fine or poorly thought out and filled unnecessary details. Here is the link for story/lore right here and I hope I'm using the right flair for the post. *Edit: There's much more the world and inhabitants to talk about, but I wanted to save them for later as someone once told me, "For games, you should either work on the story first or gameplay first. Doing both at once will be hard, so i would continue fleshing out your future timeline version of earth until you have a rough outline of the story. Try to follow act structures and do some research on 3 act structures to help you decide how the story should go. Once you have the basic layout done, then you can add all the details like game mechanics and names and stuff. My #1 rule is don't get too attached to an idea. Be willing to let that idea go if it makes for a better story, no matter how cool or awesome of an idea it is. You can always use it later unless it's integral to your main idea." I feel like it is really good advice.

A 3D solid state hardware that stores a 3D database isometrically related to the real world.

A 3D solid state hardware that stores a 3D database. but it works more like a detector, a sensor than a database itself. the point is, the sensor would then result in a readable 3D database that will change with any disturbances interfering on it.

.

Despite tiny (but could be huge like 10m3, every vector data would be stored in a physical location isometrically identical to the real world it occupies.

.

The idea is: this storage should be susceptible to interferences and disturbances, so that the database will change based on the real world interferences it occupies.

.

So may be we could create some kind of volumetric reading of the intangible universe that may exist overlapping ours.

.

Or if souls exist, it could become a way to communicate with them.

.

Also some questions:

.

Anything like that exists in the real world?

.

Or may be some scifi movie?

.

If not, spice it with a cyberpunk universe please xD

SciFi fantasy at the end of time

Got an idea for a sci-fi fantasy story at the end of time in a megastructure feeding off a supermassive black hole in the middle.

"An endless eternity of time has passed since the progenitor race first took to the stars, and now all we have are stories of these mortal gods that created this realm and our various species eons ago, only to vanish from our endless world.

As a result even a true description of what they looked like has been lost to time.

Their Ancient technology advanced to such a point that they could grab hold of and modify reality itself.

A power indistinguishable from magic.

And so they took this great power and infused their beings with it, each member of their race becoming individual masters of their reality.

Then they created the realms and they created us to bear witness to its beauty.

Blessing us with potential in our blood to control their ancient Magick”

The story would take place in a Birch world megastructure consisting of 280 million layers of artificial sphere worlds around a supermassive black hole, each sphere separated by 130km of space between, all of them having between 0.9, and 1.1 G of gravity exerted on them by the black hole.

For context just one of these layers has an absurd amount of land area even compared to all planets in the solar system combined.

In this world humanity has diverged evolutionarily in an extreme manner over trillions of years.

Either by modification to their own genome, turning themselves into digital beings or simply letting evolution do (or not do) its thing.

But while they could escape their own mortality, entropy kept pace. The heat death of the universe was upon them, their last bastion a megastructure with the same terrestrial living area as thousands of galaxies worth of planet surface.

In the end a decision was made by whatever humanity had become by that time, to leave this universe altogether and simply search for a newer one.

Those who decided to stay behind in the dying universe continued to change over the countless eons that were left until true heat death.

Devolution occurred over millions of years, and now the true nature of the world has been lost to those who consider themselves scholars of the world that remains.

Quality of life is a far cry from that of the hyper-technologically advanced ancients and the people of the outer realms live lives more similar to that of those in a fantasy setting.

Some are born "blessed" to have a measure of control over the nano tech present in their blood, and thus have "magic" whos power is limited by visualization of the physical sciences that have been lost to time.

Either that or a fundamental understanding of the nanobots themselves is required to use them for anything greater than their passive function of lengthening lifespans, and augmenting healing processes. (For instance, casting sonething like electricity magic would require extensive knowledge electrical forces and outcomes)

“Magic is said to be limited by the intellectual knowledge of the individual.

Such is not the case for the constructs of the ancients who are said to safeguard the inner realms of the world, and exude control over reality.

Perhaps some of the gods still live in the inner realms, and we are simply being insolent by attempting to witness them.”

These countless worlds above and below are separated by thousands of ancient Wormhole gates constructed eons ago throughout the realms.

A gate is typically held inside one of the structural pillars spaced equidistant from one another throughout the realms.

Oftentimes these support structures are wider than mountain ranges, stretching into the sky so high that they fade into the blue sky littered with clouds, their tops no longer visible from the ground.

Though to speak of portal travel is to speak of myth and legend, as fully traversing even a small fraction of ones own realm takes lifetimes with the technology available.

To speak or even have knowledge of the other realms, even rarer.

The story would center on heros with great affinity for Magic.(high concentration of nanobots within their blood)

The protagonist and their peers are sent on a last hope quest to venture into a functioning wormhole gate to the inner realms and find a solution for the gradual depowering of segments of the outer realms.

“Thousands of earth sized landmasses are falling every day to a cold darkness slowly enveloping and freezing everything in its path.

Tens of trillions of living beings die every day.

Several hundred thousand layers have already been compromised, and there is no end in site.

This has been the situation for hundreds of thousands of years, an unchanging trajectory for catastrophe.

You are the new hope. A group of some of the most gifted wielders of Magic in the local area of your realm.(Local in this case being earth sized)

Find the secrets of the ancient gods, unlock their power and save what is left of Existence”

As they get closer to the center structures and the black hole itself, time dilation comes into play as they now live hundreds of thousands of years for every one spent in an inner realm.

In turn the inner realms are significantly more technologically advanced as the group descends.

The conclusion would be a meeting with the superintellgence near the center, and a revelation of the true nature of the world. Followed by exodus from reality.

I had originally started working on this for ttrpg but it would probably be better suited to a book.

Would love some feedback on this ship layout

Link below. This is a research vessel. I need the layout since my story revolves around people navigating this ship almost exclusively, and due to some strangeness (time shifting, people out of phase) they can find themselves almost anywhere. I need a way to keep track of things, so a map of the ship makes sense.

I think I have all the main things that make sense, and of course this doesn't need to be perfect. Wondering if anyone sees anything obvious missing, or something that might be fun to add in.

Check it out here, there's just two decks.

What Sci Fi Book is this (Description, No Pics)

Ok! I was recently talking to a friend of mine about a SCI FI book that I loved when I read it in high school around the early 2010s. He asked me the name of the novel and I completely blanked. Please help!

Synopsis: From what I can remember. The book starts with a tech expo where this company (think apple/google) unveil this new technology involving a viewing window. This portal can see anything at any time at present, and the use of the technology explodes. The entire novel is more about how this technology is used and spread then about any individual character. They end up using, and upgrading the portals to sculpt their bodies, create masks of a roman mans face, create a hive mind to stop a meteor from hitting earth, disproving religion, and create clones implanted with the consciousness of every human who has ever lived.

Any help would be greatly appreciated!

If Brer Rabbit = Bugs Bunny, does Bugs Bunny = Anansi?

If its true that Bug Bunny was based on Brer Rabbit, a character from African-American Southern folklore, given that many of the Brer Rabbit stories where transfers of direct African myths of Anansi, a trickster-god most often known as a spider - and shapeshifter - then wouldn't that make Bugs Bunny another, the latest, form of Anansi? A spider in rabbit's clothing as it were.

Long way around a story idea of an animator or film archivist finding this out, that long ago WB locked this "True Bugs" away to keep something "bad" from happening, and the hero of the story has to fight to keep it from escaping.

Figure it could go a horror route, since we are talking about a spider bursting out a rabbit, or since as a trickster, a teacher, Anansi's freedom leads to a good ending.

A peaceful futuristic society with a secret past

TLDR: I've come up with a Utopian future, but with a dark and forgotten past.

So the world I've came up with is set 800 years in the future in a Solarpunk world. A lively, environmental world where society lives in peace with nature, powered by advanced renewable energy like solar, wind, and hydroelectric energy (solar panels and wind turbines are pretty common sights here). Revolutionary biotechnology is used for medical treatment, gene therapies, and bioengineered plants. Some people have superpowers that are either natural or genetically engineered such as: Nature Manipulation, Bio-Energy Manipulation, Technopathy, Energy Absorption, Photosynthesis, and Atmokinesis. Magnetic levitation trains and solar-powered airships powered by clean energy are used for transportation as personal vehicles are rare these days. Cities are designed with green spaces, rooftop gardens, and vertical farms fused into living and working spaces. They're also planned to support biodiversity, with wildlife corridors, bee-friendly zones, and aquatic ecosystems smoothly blended into urban areas. Buildings are designed to be supportable, with recyclable materials, self-cleaning surfaces, and integrated systems for harvesting rainwater and disposing waste. Communities are often self-governed with a focus on democracy, team effort on decision-making and education focuses on ecological awareness, innovation, and community involvement. Science and technology are both primarily focused on sustainability and improving quality of life.

It wasn't always like this though. Roughly 500-600 years ago (about 200-300 years in the future for us), a mysterious, tragic event caused a worldwide blackout, turning the entire world into the Post-Apocalyptic dark ages, similar to the NBC show, Revolution. Without electricity and modern technology, society broke down into small, often isolated communities. Trading is the primary means of currency, and survival skills are highly valued. Knowledge of what the world used to be before is very limited, often passed down through folk tales or found in scattered, decaying books and other artifacts. New belief systems have sprung up, some respecting or fearing technology as relics of the past, others focused on survivalist ideas. The environment is harsh, with changed weather patterns and landscapes damaged by past disasters. Resources like clean water, food, and medicine are hard to come by, and pieces of advanced technology are scattered. Communities often rely on basic agriculture, hunting, and foraging. People have reused old-world technology, including windmills for grinding grain, water wheels for mechanical power, horse-drawn carriages and steam engine trains for transportation. A lot of people are skilled with mechanical and kinetic weapons from scavenged parts like: crossbows, swords, makeshift firearms, and bombs. Without modern surveillance technology, stealth becomes a more effective strategy, using their environment to their advantage.

The general synopsis is that the protagonist is part of an experimental project to completely transfer their consciousness through time to possess the body of an ancestor or descendant. They're then sent back 600 years into the body of a skilled survivor living in a post-apocalyptic world. Resources are hard to come by, and pieces of advanced technology are scattered in a world slowly fighting to rebuild itself. The protagonist realizes that they're about to uncover hidden flaws or forgotten truths in a seemingly perfect world, how the downfall in the past could've happened, and what led to the Utopian society they're in right now. I call this idea "Time Bound" for now, and I'm curious to know what your future societies are like?

What thing in science fiction do you think is the closest to reality?

I'll go first: prosthetics that imitate human body parts. Something that can function as well, if not better than human parts and provide the same sensations as them. From what I know, they're already working on limbs, hearts and many other parts. Honestly, out of all the things in science fiction, I have found that cybernetics (the concept) are of the only things that do not actively break the laws of physics or are completely illogical.

The main issues currently are obviously biocompatibility and energy. I think we could solve both.

Sanity check on my thrust drive engine

I've been chatting with ChatGPT, trying to work out a reasonable thrust engine for ships in my universe, for shorter trips (Ships also have FTL "jump" drives).

I think I have something that works, but I would like some other eyes on it. I am not going to be giving readers all the details, but I do want it to make some sort of sense, even if most of this stuff in SF in hand waving.

My thrust drive is an ion drive. It has a top speed of 10 kilometers per second. It takes a little over 2 hours to reach top speed or decelerate. A trip of 25,000 KM would take just about 5 hours.

I chose ion drive, I suppose it could be any tech that could achieve these speeds. Thoughts? Suggestions?

Could Blue stars that include Neutron stars/pulsars, QWR similar to HD 45166, B-type star slightly less massive than Regulus that experienced a similar mass transfer, and a 20124 kelvin White dwarf star be hypothetically terraformed?

What conditions would need to be considered when terraforming a hypothetical super earth in the habitable zone of any of these celestial bodies? I’m curious because I’m currently thinking of building a system in universe sandbox where life develops and evolves on a massive super earth that’s roughly 3.00 or 4.00 earth masses with oceans, continents, and a mostly tropical climate that has been terraformed by an alien race from a small A-type star and placed in the habitable zone of one of these celestial objects, I’m curious to know which of these celestial objects is the most promising to develop life in based on temperature, lifetime, and instability of these celestial objects.

The Great Ring: Yefremov's genius idea of interstellar community

In I. Yefremov "Andromeda: A Space-Age Tale" spacefaring civilizations are connected via The Great Ring.

Humans haven't discovered FTL travel or communication. But one day they heard an alien radiowave sygnal. They decoded it and found out The Great Ring's communication code, and were soon be able to understand and correspond the messages.

The Great Ring is a remote communication network that connects civilizations around galactic centre. Each Great Ring world works like an uplink: it recieves messages from before and send them further, through the chain of other worlds.

New worlds get technologies and information from older worlds; older worlds get new information from newer. Each world is interested in continuing and developing communications.

But among all humanity's neighbours nobody knows who launched The Great Ring.

I found this paricular idea great. But overall book was mediochre: way too declarative and communist-righteous.

Mind decaying into madness

I was always fascinated by the idea of going "too far" into space, discovering things the human mind can not comprehend. I think one aspect I like about this is the lovecraftian cosmic horror but also the opportunity to introduce some new dynmaics.

As example I take:

Do you have more examples for this?

I wanna analyze them and see what I can extract there for my own story.

It can be vague or not but I think for my story a more vague concept only adds to the mystery.

Note: This is not the main focus of my story but something that will get named here and there and is only for "universe enrichtment purposes".

Concept ideas?

So I want to make this story about this girl who is sent to live with a foster family after something happens to her mother (haven’t decided yet), but said foster family died too. She was close with her foster family, so it motivated her to fight against the oppressive government (or some time of oppression rule…I don’t want it to be cliche) that killed her foster family. I want her to like have time powers but don’t at the same time because it’s a metaphor for something I haven’t decided yet. I want to know some ideas on who I can make the narrator. I don’t want to make it the girl because that feels boring but I also don’t want to make it 3rd person. Maybe like 1st person, but the narrator is telling the story of the girl and can move on to other places. (Kinda like death from the book thief if you’ve ever read that). Any ideas? Other feedback is welcome too

Feedback for new species

So a friend and I have a story where instead of an apocalypse with zombies, there are Shadows.

In a hidden facility deep in the Ural Mountains, a coalition of scientists from around the world was working on unlocking the secrets of the astral plane. Their goal was to tap into this dimension, theorized to be a realm of pure emotion and consciousness, as a potential energy source.

A team of scientists created a device known as the "Astral Conduit." It was meant to siphon minute amounts of energy from the astral plane. The initial tests showed promise, but as they ramped up the energy input, the Conduit became unstable. Instead of siphoning energy, it tore a rift between our world and the astral plane. The astral plane, being a realm of emotions, memories, and consciousness, began to leak its essence into our world. This essence latched onto the strongest emotional imprints of living and deceased individuals, giving birth to the Shadows.

The Shadows themselves are feature-less silhouettes of people's emotions, with fully white eyes. The lesser ones act as an inconvenience depending on the emotion they represent, and the higher ones pose a higher threat.

The breach in the astral plane was not static. It continued to grow slowly, causing the number of Shadows to increase and their manifestations to become more potent.

As time progresses, the Shadows have the ability to develop, becoming more than just mimics. They might gain the ability to speak, revealing hidden regrets or secrets of the people they resemble, further blurring the line between reality and the astral.

My question is: Does anyone have any advice on how we can improve?

HiDAR (Higgs Detection and Ranging)

“Higgs Detection and Ranging” is a highly accurate method of detecting and measuring objects at distance. Though it is essentially capable of determining distance and velocity, the primary advantage of HiDAR over conventional detection and ranging systems is the ability to determine mass and density. Additionally, due to the quantum mechanics of this system, HiDAR is capable of knowing this information instantaneously, unlike RADAR which is limited to a function of distance and light speed. It therefore bypasses certain conventional laws of general relativity (see safety notes).

Using the observed mass and density of an object, it is also possible to assess the possible makeup of the object. Heavier component elements are easier to distinguish, given their greater Higgs Potential (e.g. Radon would distinguish easier than Hydrogen, and neither would show on conventional RADAR due to their natural gaseous state).

HiDAR’s effectiveness is affected by the equipment’s resolution. Equipment with higher resolutions can assess objects with greater certainty, and work effectively with wider scopes. Although HiDAR can theoretically detect a mass at any distance, the inverse square law still applies. Greater distances include greater noise into the resolved data and therefore; the effective distance is limited by the maximum resolution. Technologies such as machine learning algorithms are commonly used to extend this range and clean up noise. The radius at which this is necessitated, however, is referred to as the Yellow Line. The radius at which no reliable data can be discerned, even using any algorithm or neural network currently available, is referred to as the Red Line.

Principle

The HiDAR system leverages the Higgs Relationship inherent to all Dirac Fermions (Fermions with mass). This means that HiDAR cannot detect photons (e.g. a laser), Mesons or any Weyl Fermions (Fermions that lack mass). It is possible to reconfigure the system to detect other particles, so long as they are accompanied by a Higgs Boson.

During operation, the system measures the potential of the Higgs Field at a point on a given vector. The point is expressed through a series of entanglements at the core of the quantum unit. These points within the machine’s matrix become exact quantum duplicates of the target point, however the mass does NOT interact with systems outside the equipment. During observation, the system introduces approximately 246 GeV per particle to develop a vacuum expectation value within the Higgs Field. This results in Tachyon Condensation, which is the only product of this system that can be observed. Mass is determined by the quantity of Tachyons. Density is simply determined by initially introducing only 246 GeV, as this will only produce tachyons from one particle and therefore provides a baseline.

The system, upon detecting significant mass within a sample area, will iteratively scan the surrounding area to determine the size of the object. Once the bounds of the object are determined, velocity may be calculated by the change in bound projection (an object appears to take up more area may be moving closer, however this is a known way to fool a HiDAR system).

Uses

Although HiDAR is highly accurate, scanning a large area is not quickly possible at an effective resolution. For this reason, the most common implementation of HiDAR is in hybrid systems where RADAR will identify an object and HiDAR will then determine the mass, density and probable properties.

It is theoretically possible to disrupt HiDAR systems using Lepton Interference. Though mostly theoretical at this time, Lepton Interference would be a scenario where an area is flooded with an example Lepton (in most models, Tau Neutrinos are the only practical example) that would make an object appear far larger than it otherwise would be. Though this would not disrupt the function of the system to detect especially heavy elements, it introduces mass-noise. Where an object may have appeared consolidated and whole, mass-noise would make it appear more like a gravitationally-held stellar mass. Potential solutions to this problem have been postulated, including the use of a second HiDAR system configured to detect Gravitons. This scenario is still entirely theoretical however, and so little time has been dedicated to solving this problem.

Safety Notes

HiDAR is a system that bypasses certain principle laws of General Relativity by using tachyons to convey information faster than the speed of light. Although there are certain mathematical precedents for this to be possible, HiDAR is not one of them. It could be said that this system violates the laws of time itself. It has even been theorised that it could be used to view events before they happen. Experimentation into this theory was made illegal for a variety of reasons, and warnings should be respected by any engineer working on HiDAR systems:

If any system exhibits abnormal and/or desynchronous chronometric behaviour, discontinue use IMMEDIATELY. HiDAR is a quantum system and therefore should be impossible to fall out of synchronisation under normal relative terms. Desynchronous behaviour may be indicative of a temporal paradox in progress. There is not enough research to understand what the consequences of viewing future events will have. The threat of legal action pales in comparison to whatever consequences time itself may have for you, should you try to violate it.
