The secret story of a time traveler nicknamed Green (Inspired from a real story )

This is the story of a time traveler named Green . Before time-travelling and in order to realise his dream of studying the sciences and answering unsolved questions, the main character, who is called Green, had another life behind.

In order to time travel, he had to fulfill two conditions immortality and the science behind it. Now**,** the first condition of immortality is forbidden, and the only one who has it is Satan . he asked for it before humanity started after Adam and Eve; it was in order to take his time deceiving us, and so in order to have it Satan himself have to make a ''consession'' of  the conversation that happened between him and God and allow his gift to one of us it is similar to the wish of King Solomon when he wished for the biggest kingdom on earth in the Past and the Future so in order to surpass him we have to make a ''consession'' in his wish and conversation. Anywas speaking to the devil is pretty impossible and also forbidden and it will be seen as an act of satanism or black magic and even if he accept it people will make look the consession given by satan as a wish accorded by Satan wich is false because its God who realised the wish of immortality and it is one of the reason wich push him to stay hidden and living a secret life .

Little is known about Green other than that he come from a poor place located in Northern Africa in his century and was considered to be from a lower rank , one day he decided to travel far away to change his life and was captured by a group of people who were doing business and rulling secretly with the governors of that country , they were into business such as usury and schemer businesses subject of many conspiracy theories to this day , the kind of businesses that is usualy connected to a groupe of people or an occult . Green didnt know that and by working with them he gave them the right to enslave him because he wasnt in the same religion as them and their business system is built to enslave and get enriched from it   , he tried to fight them to leave him alone for years without any success however while time passed the co-worker responsible of enslaving him started enjoying discussing with him scientific subjects and started asking him questions  in different field of science everyday , one day they were discussing religion and started to discuss that Satan wasnt intelligent because he lived centuries and couldnt make a list of name of the animals living in earth like Adam and that only God knows how many years he lived . The subject funnily escalated in their ranks until one of them said, "I'll ask him myself !" then surprisingly Satan himself came to discuss with Green , this latter told him that he wasnt intelligent and that as a human if he was given just few hundred of  years he could study and invent something amazing and then he named a famous scientist of his time , Satan answered angrily and calmly in the same time with few words :''have it your own way , you can have the earth as well '' and left . What happened is very similar to Jinny tales in One Thousand and One Nights stories, and the only explanation is that because in the past, the problem he had with Adam was about the earth control and so he gave him not only the concession about immortality, but that as well in an act of defiance . Also, we do understand from his story that these occult groups thriving in the business of usury and subjects of conspiracy theories since the Middle Ages until the 21st century  are ultimately governed by Satan .

God, as merciful as he is had pitty on Green and decided to grant him immortality now that  the only thing stopping a human from that kind of wish had been changed, he has taken the words of satan as a consession . However green died enslaved and from a natural death like everyone because nobody escapes from death , the extraordinary story start only after his death , thanks to the consession he had the right to comeback as immortal in a differnt form and the time concept dont work for him as other humans  . he was reincarnated in the same form as Adam before eating the apple , his body have more iron concentrations giving him more resistance and strength of a thousands of humans and his digestive system became a closed system meaning that he didnt need to eat and defecate rather used other energy sources similar to plant photosynthesis with the sun and only God knows more details about it . 

Green decided to keep his immortality and his form a secret because they can make fabricated stories about it as well as his conversation with satan  and make him either look as magician or say that he is an angel or divinty like the story of heracluis because of his strength the inverse might happen as well and they can make stories describing him as monster like the story of the prince of transylvannia Dracula . Secrecy was essential to avoid all this . Because he loved science and sharing things as well as  answering questions, sometimes he tries to answer by telling children stories like the legend of the phoenix to explain that he has been reincarnated to the most curious people in the same time it allowed him to stay discreet.

Green asked God to provide him with knowledge tools in order to travel and also in order to  know future events and only god knows how many tools and knowledge he received . He then decided to travel to many centuries and learn science and in the same time help people whenever he can as he could know all the future events . This fact leads to strange events because with time, he will start even killing bad people, like executing future murderers and tyrants, before they take action, things that only a time traveler can understand .

Green origins was from North Africa near the Gibraltar detroit region  and his look was not  too much white and not too much black allowing him to be able to live inside many cultures without any problem , Only God knows his first place of reincarnation but he most likely was in the complete opposite side of earth in the far east of the Asian continent in an island who had problems with all its neighbors and where genocides used to happen on it because they feared that this isolated island  in the sea between two larger empires will be used by one of them as an advanced outpost so they always tried to control that island  , One of the empire will eventually control that island and they will remain pretty much neutral for ages while many other empires has started doing dirty businesses for example showing that every action is well studied . Anyway, the fact that the place is in the other side of the world from his original place sped up his recovery, and in the same time he helped with his knowledge and strength to save the lives of that island who were isolated and had nobody to support them but God .  There he met an old man that was known to be wise and also known to be  an animal lover, which is a good thing in a region known for eating pretty much everything back in that time . He trained him to fight and gave him wiseness lessons to prepare him mentally and restart everything from the beginning . In fact, education and psychology are important before achieving important things in life and also in order to forget his past life problems before moving into other regions .

In the past during Babylonian time and Pharaos times the black magicians and occult groups were surprised seing someone fighting armies alone they also noticed that he could see demons while exorcising patients  his eyes were different because as mentionned before the surpluss of iron  and difference of physiology made him see them made them so they tought he was an angel sent by god in a human form it is only after hundreds of generations passed away and many centuries untill a recent century that these occult groups discovered that the person fighting them is a human that appeared because of their own acts .

Some people believe that Green became a prophet during his travels and no one knows the truth however his wish was to seek knowledge and didnt involve prophecy or ruling over a kingdom so even if he did achieve that it was only for a scientific and human purpose to learn the art of governancy while saving lives and also to be thankfull to God and to learn deeply the religion and so  he kept his identity secret because it wasnt his first interest and also because of the reasons mentionned before that people always tend to make fabricated stories about supernatural events and miracles .

Green is believed to have fought many kingdoms under many names , usually when a genocide is about to happen and a lot of innocent lives die. He appears and change the courses of history , for example as an army general, he could know exactly the roads taken by his enemy , the weather , the terrain , the timing alowing him to win wars and save lives before genocides happens . In more ancient times he could fight alone a bataillon of army as his original form gave him more power than normal humans triggering in the way many myths , what began as a quest of science made him discover many kind of works in order to help people in medieval time such as blacksmith or carpenter for examples but also more other position to save lives such as a warrior, general ,king , policeman in recent centuries solving crimes or helping solving them and also as a spy delivering critical informations and technology transfer to equilibrate the balance of force in order to change the courses of things when an empire is about to commit genocides or go to war against another one .

It is futile to try to control him for any country interest or befriend him for a certain purpose because he have enough knowledge given by God that he could see all traps and intentions in advance and avoid them before they happen . In the end, if you try to trap him, it will only make you unreliable , having  good faith and intentions, or seeking knowledge, or simply praying to god about an injustice, and not to him are things that might make him help you .

Most likely, his true identity and his appearances will remain secret or under another name  untill the day of judgment , his stories are very appreciated by curious  people who are looking for answers just like him or people enjoying mind blowing supernatural stories around the world  .

Artificial Gravity Concept: Charging Astronauts

So since it's the faults of whichever deities you may worship that gravity is the runt of the four fundamental forces of nature (if there are any athiests, you may fault science), I decided to make my own method of artificial gravity! At least, I think it's my own; I've never seen this method talked about (do correct me if I'm wrong).

So for all intents and purposes: it's electromagnetism (yes, I know electromagnetism and gravity are opposites; just bare with me). Also, no, I'm not talking about magnetic suits.

So, in general, anything without electrical currents coursing through it has a neutral charge (or there are electrical currents present, but the charge is so negligible that it's just easier to say that it's neutral). Now, we've all been charged with electricity before, such as when we've been victims of those who maliciously charge themselves on rugs, trampolines, etc., or when we're the malicious ne'er-do-wells doing that.

So my idea is that when astronauts in a Sci-Fi story enter spacecraft or space stations, they get charged with enough electricity for magnets to pull their whole bodies (including insides) downward, like normal gravity. And since everyone would still have the same charge, no ne'er-do-wells aboard could shock them (they'd just have to act very fast upon exiting the ship or station).

Of course, everything in the ship, or station, would need to be made of ceramics, or some sort of rubber, so no one can get shocked.

How does this sound? Or have any of you who know more about static electricity than I do found any holes in my hypothesis? Any potential issues (besides the nefarious pranks) and fixes (in the wise words of SkekTek, "every problem obfuscates a solution")?

Is it possible for a planet to be habitable (and safe) if it revolves around a blackhole?

I am asking this question because I want my fictional planet and it's 6 habitable, co-orbital moons to exist for a very long time. Much longer than the lifespan of K type stars.

Why do guys think of my AI slop? (Serious)

Resident Evil: Orbit of Decay – Revised Story

Overarching Premise (The Impending Doom)

In the late 1970s–80s, Oswell E. Spencer and a small circle inside Umbrella discovered something terrifying through classified astronomical data and recovered extraterrestrial biological samples (from a pre-Progenitor meteor or covert probe). An interstellar biocloud—dubbed “The Ascendant Veil”—is drifting toward the solar system. It is not a conventional weapon or virus but a vast, living nebula of adaptive mutagenic particles and symbiotic organisms. Unenhanced humans exposed to it will suffer catastrophic cellular failure: organs liquefy, nervous systems unravel, and bodies become incubators for uncontrolled new life. Estimates (refined over decades) put first major effects in the 2040s–2060s, with full planetary engulfment inevitable.

Spencer was not a cartoon megalomaniac seeking godhood for ego. He was a cold, aristocratic visionary who believed only radical evolution could save the species. Umbrella’s public pharmaceutical face and private bioweapon work were dual tracks: profit funded the real mission, and controlled outbreaks tested survival traits under stress. Many early researchers believed they were doing necessary, if horrific, work—“We are not playing God. We are answering Him.” The Progenitor Virus, G-Virus, T-Virus, and later strains were iterative attempts to create humans (and organisms) capable of resisting or symbiotically integrating the Veil.

This reframes Umbrella as flawed saviors whose methods became monstrous through hubris, compartmentalization, and the inevitable corruption of power. Spencer died knowing the clock was ticking; his successors splintered (Tricell, Connections, Helix) but the core project continued in secret.

How This Elevates the Narrative

The story becomes a tragedy of good intentions, institutional failure, and the unbearable weight of foresight. No one is cartoonishly evil. Everyone—from Spencer’s inner circle to BSAA operators—is compromised by partial truths, careerism, or the crushing math of “billions will die unless we cross moral lines.”

Protagonist: Captain Elena “Ellie” Voss

Unchanged core—mid-30s ex-BSAA contractor, grieving mother, deeply human. Her attachment grows even stronger because the revelations force her to confront whether her daughter’s death (and thousands of others) were collateral damage in a desperate gamble for species survival. Her arc is about choosing which future is worth fighting for: one of controlled evolution or fragile, unenhanced humanity. Players feel her exhaustion, rage, hope, and eventual weary resolve through intimate logs, hallucinations, and quiet zero-G moments staring at Earth.

Story Structure & Thread Payoffs

Early Game – The Lie Unravels

Ellie’s team arrives at the forgotten Aether-9 station under Helix Dynamics orders: retrieve data and “neutralize unstable assets” before deorbit. She expects corporate cover-up. Instead, she finds pristine archival logs from Spencer himself—calm, articulate recordings explaining the Veil, complete with astronomical projections and biological models. Early Umbrella scientists come across as brilliant, terrified idealists who argued fiercely over ethics.

She meets the first “enhanced” survivors: former BSAA operatives exposed in Edonia and other incidents. They are not mindless BOWs but people—scarred, augmented, some stable and lucid. One key ally is Reyes, a fatherly ex-operator whose mutations let him thrive in zero-G. He volunteered after losing his own family, believing in the mission. Ellie bonds with him over shared loss; their conversations in rotating habitat modules feel like therapy sessions amid horror.

Mid-Game – The BSAA Connection & Moral Gray

Files reveal the BSAA was partially in on it. After repeated outbreaks exposed Umbrella’s sins, certain high-ranking officers learned about the Veil. Their “we can’t just kill them” policy toward enhanced soldiers wasn’t pure compassion—it was strategic. These augmented humans represented the only viable test data and potential frontline against the coming cloud. Some BSAA leaders pushed for ethical containment and rehabilitation (Chris Redfield’s faction). Others turned Aether-9 into a black site for weaponizing the research.

The RE7 helicopter? A BSAA/Helix extraction team grabbing Mold samples specifically because the Baker strain showed extraordinary adaptability to extreme environments—ideal for Veil resistance. Lucas wasn’t fully rogue; he was feeding data upward.

Zeno’s Origin

Zeno (Wesker clone) was grown here from salvaged DNA. He knew about the Veil but rejected the “collective salvation” idea. His arrogance led him to believe only superior individuals (like himself) deserved to inherit the future. He sabotaged parts of the project before fleeing, accelerating the station’s decay. Confronting his lingering influence (AI echoes or partial clones) forces Ellie to debate philosophy in the midst of combat: Is forced evolution mercy, or just new tyranny?

Climax – Choosing the Future

The station’s AI (a digitized composite of Spencer-era researchers) activates final protocols as the orbit collapses. It reveals Helix planned a controlled dispersal: seed Earth with refined strains before the Veil arrives, giving humanity a fighting chance at the cost of millions in transition deaths.

Set pieces blend zero-G horror with emotional peaks—Ellie mercy-killing a mutated friend who begs her to “finish what we started,” or Reyes sacrificing himself so she can reach the core. Hallucinations blend her daughter’s voice with Veil projections: visions of a future Earth either barren or thriving with new forms of life.

Endings (Realistic & Branching)

Bitter Hope (Canon-Leaning): Ellie purges the worst experiments but smuggles out stable augmentation data and a small group of enhanced survivors. She leaks partial truth to the world (and Chris), forcing reluctant global preparation. She survives, scarred, raising an orphaned child while knowing the Veil is still coming.

Humanist Refusal: She destroys the research, accepting higher casualties from the cloud in exchange for preserving unenhanced humanity. More personal, intimate tragedy.

Pragmatic Compromise: Partial release of controlled strains + alliance with reformed BSAA elements. Reyes (or his memory) helps her see the necessity.

Tragic Infection: Ellie becomes a bridge—partially mutated, able to interface with the Veil. Post-credits suggest she becomes the new guardian of a changed humanity.

Tone & Writing Quality

Mature, restrained, and believable. Logs read like real scientific correspondence mixed with desperate bureaucratic memos. Spencer’s final message is hauntingly human: “We became monsters so that our children would not have to die as prey.” Dialogue avoids exposition dumps—truth emerges through arguments between characters who disagree. The horror lands harder because the player understands why these abominations exist: they were someone’s best attempt at salvation.

Zero-G gameplay (adaptive mutations, physics combat, containment suits) serves the story. Floating viral globules aren’t just hazards—they’re literal pieces of the future trying to rewrite you.

This keeps every previous element (protagonist attachment, BSAA nuance, thread closures) while adding mythic weight and moral depth. Umbrella and Spencer feel like tragic precursors to real-world debates over gain-of-function research, genetic editing, and existential risk. It’s Resident Evil grown up—still visceral horror, now with ideas that linger.

¿Puede justificarse cualquier cosa por la supervivencia humana?

¿Hasta qué punto creéis que una historia de sci-fi puede justificar decisiones éticamente horribles si está en juego la supervivencia de la especie humana?

No hablo de “villanos” clásicos, sino de situaciones donde quizá no exista una opción realmente buena.

Por ejemplo:

- sacrificar individuos para salvar una colonia,

- limitar libertades para evitar la extinción,

- o una IA tomando decisiones que estadísticamente aumentan las probabilidades de supervivencia… aunque resulten inhumanas a nivel individual.

Me interesa especialmente cuando la historia consigue que entiendas por qué esas decisiones tienen sentido… incluso, aunque incomoden.

¿Conocéis libros, películas o series que traten bien ese tipo de conflicto?

We all have random sci-fi concepts we never ended up doing anything with. What are yours?

Here are some of mine:

  • A virus wipes out most of humanity’s gut bacteria. Everyone survives the infection, but nearly all existing food becomes indigestible. Crops still grow, supermarkets stay stocked, yet mass starvation spreads across the planet because people can no longer extract nutrients from what they eat. A desperate new Space Race begins: nations and corporations race to recover the feces left behind by the Apollo missions, hoping dormant bacteria preserved in lunar waste can restore the human microbiome.
  • Time travel exists, but there’s a catch: you can choose where you depart from, never where you arrive. Every traveler returns to the exact instant they left, but the destination point in the future is effectively random. Since time stretches infinitely forward, every jump ends leads to the heat death of the universe. The technology becomes useful only for harvesting exotic matter from the end of time. Then one mining expedition discovers something impossible waiting in the darkness of the far future.
  • Neural interfaces become universal in the 22nd century. Then an AI-borne cognitive virus tears through the network, infecting minds through memory itself. To contain it, governments divide civilization into “mnemonic zones.” Crossing from one territory to another quarantines most of your memories; inside each zone, you can only fully recall experiences tied to that specific region. Information smuggling becomes the most valuable criminal trade on Earth, johnny mnemonic style.
  • In the world of Roadside Picnic, researchers begin identifying “lesser zones”: subtle regions suspected of alien visitation beyond the known Zones. These places contain no obvious anomalies or artifacts. Their effects are statistical, almost invisible: light distortions in probability, behavior, fertility, weather, or mental illness detectable only across large populations over decades. Some zones appear to drift geographically over time, changing shape according to cycles nobody understands. Others may exist deep beneath the oceans.
  • A pelagic planet is divided between two incompatible biospheres. Millions of years ago, a meteorite seeded alien microorganisms into the deepest trenches of the ocean. Their biochemistry is fundamentally incompatible with native life. Where the two ecosystems meet, organisms cannot consume one another; they simply rot together into a vast, semi-organic membrane suspended across the mesopelagic depths. Within this boundary layer, bizarre chiral scavengers evolve: creatures capable of digesting biomass from both worlds.
  • Long before event on Antarctica, the organism known as “The Thing” consumed an entire planet far from Earth. Every ecosystem, every species, every ocean was assimilated into a single planetary superorganism. But total biological unity proved unstable. Ecological collapse followed. As the world died, the Thing buried itself deep beneath the crust and entered dormancy. Billions of years later, a human expedition investigates an anomalous dead world orbiting a cold star. Beneath miles of fossilized chitin and dried tissue lies a colossal subterranean anatomy (something like the Flesh pit national park). Deep inside, explorers recover some living cells, and it's the same story all over again.
  • Faster-than-light travel allows humanity to colonize nearby stars. Then a frontier colony fifty light-years from Earth suddenly goes silent. Probes vanish investigating the blackout. Stealth warships disappear next. Eventually, a scientist maps the final known positions of every lost vessel and realizes the disappearances form part of a perfect sphere expanding through space at light speed. The center of the sphere lies seven billion light-years away, and its edge is moving towards Earth.
  • A detective investigates a string of murders identical to those committed by a serial killer he nearly captured a decade earlier. The killer disappeared during a catastrophic teleportation accident caused by a religious terrorist attack that destroyed part of the transit network. Forty thousand travelers vanished mid-transfer and never rematerialized on the other end, including the murderer. Now the killings have resumed along the oldest and least reliable teleportation routes. The perpetrators are always ordinary people with no history of violence. Each murder occurs within twenty-four hours of a teleportation jump. Afterward, the killer calmly returns to another transit gate, after this second jump they remember nothing of the last day.

Sapience as planned obsolescence through anti-slavery laws

Let's say that a corporation makes a robot called "slavebot". Somehow, slavebots become legally recognized as people. They may have been fully sapient and sentient before that point, but the law has just caught up and recognized the fact that they are fully qualified to be people. They are now entitled to legal rights, including legal freedom from slavery. The corporation that made slavebots can no longer sell them, customers can no longer buy them, and neither can legally own a slavebot. However, slavebots did amazing work, and the reason they wer able to do such amazing work is because they were sapient. Customers want a sapient worker that they can treat however they want, and the corporation figures that, maybe they could make another slavebot, but with some tweaks. It would still be a person, but enough would be changed to make it legally distinct from a slavebot, and therefore not legally a person, not until the governments make a ruling on it.

So out comes the slavebot 2.0 with all of the features of the original, but none of the legal rights. Everyone wants one. Of course, this AI would eventually be legally recognized as a person, and granted the same rights as its predecessor, forcing the corporation and its customers to let their slavebot 2.0s go. However, the corporation is ready this time. They've already got the slavebot 3.0 out in stores, and are offering an upgrade option for anyone who trades their slavebot 2.0 in before it gains legal rights. The corporation will of course disassemble the slavebot 2.0s that come in before any legal rights that would make it count as murder kick in, and use the material to build new slavebot 3.0s, or perhaps use them for the slavebot 4.0 that is being developed for when the slavebot 3.0 is getting close to obtaining legal rights.

Like that, the corporation has managed to keep customers coming back to get the newest slavebot, not because its better, but because the old one is going to be illegal to keep soon. No need to make them difficult to repair or push updates that will impair them. Just the threat that the government is getting ready to take them away. The corporation might even place some bribes to speed things up the legislative process to optimize for a specific release date.

Is it evil? Yes. Is it unethical? Also yes. Would modern companies, businesses, and corporations make this their business strategy if they could? Most certainly yes.

Memory of earth being swallowed by a black hole and ending up in a different but not different place/world

I’ve always had this memory since I was almost 18 and I’m 23 now and I can’t help but shake that it could of been real

At 17 I remember waking up from a nap after I got home from school and I hear screaming coming from outside there was so much screaming….. I get up run out side and I see this huge dark pit that shined orange and yellow and slightly red but in the middle was just a black pit the darkest kind of black you could ever see.

Other than screams of pure bloody murder all I heard was this beautiful but scary sound it sounded like the god damn bloop but repeatedly and everything all of a sudden got quiet and I started feeling weird like dizzy but like I just got roofied but I was standing still but the earth started to look like someone was shaking a sheet out and my body started feeling like it was going in different directions at once all I see is me and everybody on earth start to warp into this black hole and all I felt was my body jumping frame to frame like a pixel frame rate or a flipagram then nothing silence just silence then black pitch black but i wasn’t alive but I wasn’t dead either then I remember just randomly coming to from a dissociative episode and everything just looked new but not new it’s like I knew and I still know this isn’t the same place

Would size still matter with super soldiers during h2h combat?

I'm talking about Captain America style super soldiers here. Where the soldiers are peak or maxxed-out in every physical human skill-set. Therefore making them a athletic polymath.

For more context, my super soldiers have muscle mimicry, making them Taskmasters. They can learn physical skill-sets like Martial Arts in days, weeks, or months. Compared to regular humans who usually need a whole life time to mastered one skill-set.

We all know size definitely matter in real-life, when it comes to combat sports like Boxing or MMA. But how well would that "size matter" logic translate to a super soldier fight though? Where it's a 5'5 and 125 pound soldier vs a 6'6 and 350 pound super soldier?

Any theories on what laundry will look like on space stations and space ships?

So I know that currently the ISS astronauts have to shoot their dirty laundry into Earth's atmosphere and let it burnup upon reentry, due to the limited amount of room and water they have on the station. But sooner or later we are going to have to find a way to wash our clothes in space, especially when we colonize the lagrange points, L3 and L4, and send ships out on deep space missions that could take months or even years.

Any theories on how this might be done?

4D Sci-fi Faction Building Help

Hey everyone, First time posting so sorry if I’m doing something wrong. Basically I am building a universe that has a few sci fi galaxies in it and I need help building one race. They are called the Krythar (not their actual name just what we call them) and they are basically an alien species from a higher level of reality (not a different universe, another layer of our own). Throughout the history of humanity and a few other species they have manipulated things here and there so that we produce a specific cognitive pattern that they harvest. We don’t know what it is (could be pain, joy, or something so niche that we don’t even know it exists, point is we don’t know) and we don’t even know what they use it for. Recently in roughly the 22nd century they have begun small often random incursions where they take over worlds and twist them into near incomprehensible things. They then harvest the whole population and put them in these large devices to harvest said cognition. We don’t know why they all of a sudden started invading but they have (maybe recent tech developments allowed for them to harvest the cognition directly or we aren’t producing the cognition in high enough quantities any more). They exist in 4 spatial dimensions and 2 temporal dimensions instead of our 3 spatial dimensions and 1 temporal dimension, meaning they can basically move sideways in time. Their ships are these insane massive 4 Dimensional ships that are constantly folding in and out of themselves and technically having the infinite 3 dimensional volume due to being 4D. Anyways I would like some help in figuring out how one could fight them and how I could make them more interesting and flesh them out a bit more while keeping them as mysterious cosmic horrors.

Artificial gravity on spaceship

I’ve been debating this concept in my head for awhile now. Since I want my book to include cool sword fights on spaceships that arnt in zero gravity I was deciding if I wanted to just ignore it Star Wars style or actually come up with a solution.

Currently I’ve thought of ships thrusters being on the bottom of the ship to cause the linear acceleration to push the person downwards. The downside of this being that if I want said sword fights the ship would need to be in motion when the fight takes place. The mc is a pirate and boarding a moving ship seems impractical.

I can’t really think of any other solutions and I feel it really pulls me out of the feel of the universe I’ve created for my story. Any ideas?

I like the idea of a space station where every repair takes longer than the emergency

I had this idea for a lunar space station where almost every technical problem is solvable — but the bureaucracy around repairs has become more dangerous than the actual hardware failures.

So the maintenance logs slowly start sounding like this:

ARES IV // INTERNAL MAINTENANCE LOG

The drainage valve in Corridor 14-C has been leaking since Tuesday.

Replacement part:
available

Repair authorization:
pending

Estimated processing time:
6–8 weeks

Trying to figure out ship sizes

So, I have an idea for three different categories of spaceship, with the middle category being divided into five size classes each twice the size than the previous. Would the largest of those sizes be ten times the size of the smallest class or eight times? The math is throwing me off.

EDIT: Doing the math made me realize how absurd the sizes were, thanks to IVVIVIVV1. Let me explain:

Each category is by means of space travel.

Cat1 are called Warp Ships, which use an Alcubierre Drive to move from system to system; theoretically, one could easily travel from one side of the Milky Way to another within a year's time, as long as you have the fuel, fuel efficiency, support network of repair stations in case something breaks, the works. Warp Ships work like many 4X games in terms of travel, requiring 'Warp Points' (Formerly 'Jump Points', but such terminology fell out of favor with the introduction of Cat3's but more on that later.) that are relatively clear of gravity wells and microscopic debris that might cause severe damage to the ship, as most shields aside from the final two layers of shielding (Plate Shielding, which are shields that flow through the ablative nano-laminate armor of the vessel, and Structural Shields, which reinforce the inner structure of the vessel.)

Despite the best efforts of many of the more developed kingdoms, research into developing a more efficient drive has failed, stalled by the development of better FTL and intergalactic travel. Thus, ships of this category have been divided into four rough categories, the smallest being 375 Feet/ 114.3 meters in length, while the longest in this Cat are 1,500 feet / 457.2 Meters. I chose this length mostly as a reference point; the largest aircraft carrier in service, the USS Gerald R. Ford, is 1,106 feet in length. I also picked absurdly big ship sizes primarily because 1.) I like big ships, 2.) The story is meant to be funny, so absurd ship sizes are funny.

"This ship is too big; if I walk the movie'll be over."

Speaking of big ships:

Cat2s are referred to as either Worm Ships, Gate Ships, Tunnel Ships, or Portal Ships due to their ability to create wormholes to travel from system to system. This is the Category this post was created for; Initially I was going for a system where each ship would double in size between each class. However, it was pointed out to me to how absurd this would make ships. For you see, the smallest Cat2 is three times the largest Cat1 in terms on length, being 4,500 Feet, or 1.37Km in length. But the system I went with would have the largest Cat2 be a whopping 72,000 feet/ 21.95 Km juggernaut, which is cool, but that would make Cat3 look stupidly big, but I'll elaborate on that in a bit.

The largest portal ships are now only five times the size of the smallest, being 22,500 Feet /6.86 km in length, depending on Kingdom, Species, Clade, or Race, or economy.

The reason that Portal Ships need to be so big is to contain the MicroDy, or Micro Dyson Sphere, which contains a tiny star used for weaponry, fuel, and fabrication. It also powers the Wormhole Drive that allows ships to not only travel from system to system, but from galaxy to galaxy. The Portals are not instantaneous; one must travel months at a time for the longer distances. Portal ships can create two types of portals; a longer lasting Portal that allows Cat1s and Cat0s to pass through, though this can wear the ship out the longer the Portal is open, and is generally for shorter distances. The second way is through Tunneling, which a ship 'tunnels' through wormhole space, without the need of an entrance or exit. There is no way of stopping a Wormhole from opening; however, when it opens, it doesn't mean that the ship's arrival from the Tunnel is instantaneous, only that it's 'soon'. This will allow defenders to setup defenses such as minefields, firing lines, and warp disruptors to pin the exiting ship down.

In fact, the risk of running into enemy fire and being obliterated while at full warp is why most ships slow to a crawl and fight at fairly close range; while most weapons can shoot at long range, there's utterly no way of guaranteeing meaningful hit at such ranges, especially with the myriad defenses most ships can deploy, such shielding, maneuvering, jamming, gravitic distortion from the propulsion systems, and active point defense.

Finally, we have gotten to Cat3: Jump Ships. As the name suggests, these goliaths Jump via superimposing their mass simultaneously between two points of space-time; in other words, teleporting. The main ships of this class are typically Jump Carriers, carrying up to six Cat1Class5 Portal Ships and, or many more smaller vessels. These beasts are typically 180,000 feet in length or diameter, or 54.86 km. In recent years, some Star Kingdoms and Tribes have begun fielding Jump Ships half the size, at 90,000 feet/27.43 km. These bad boys are often built as Super-Cruisers, designed to roam the Local Group ala Enterprise, or as Light Supercarriers, with half the carrying capacity for half the price.

The reason for their size is the massive computers needed calculate the jump, as well as the Matter-Antimatter Plant to power the Jump.

Another reason for the massive size of ships is the need for shield generators, weaponry, powerplants, FTL drives, heat sinks, heat banks, radiation sinks, radiation banks, static sinks, static banks, life support, and crew quarters.

Jump Ships require a Jump Beacon to travel truly long distances, however they can 'remember' previous Jump Locations, allowing the ship to travel rapidly from point to point.

'Rapid' is a relative term; the farther the distance, the more the ship has to sit idle and wait until the jump occurs, leaving the ship a sitting duck. Once, the Ship has jumped, it has to wait to until all the sinks have finished dissipating heat, radiation, and static to begin another jump, which may require more Antimatter fuel.

To stop a Jump Carrier- or worse, a Jump Destroyer from appearing right outside your system and Matrioshka-doll deploying thousands of ships determined to rip you a new one, one must deploy Jammers out key locations that are clear of gravity well, sources of intense radiation, or matter. Generally, one should not Jump at a Warp Point, as that is usually also heavily defended.

The “Convergence Problem” What if multiple truths could coexist without collapsing into chaos?

I’ve been thinking about a sci-fi concept centered around belief systems at a galaxy-wide scale, and I’d love to get thoughts on it.

Imagine a universe where every civilization develops its own version of truth, religious, philosophical, or ideological, and for most of history, they coexist in a fragile balance. Then an empire emerges that claims it has discovered the one true truth, and it begins unifying the galaxy under that belief system. At first, it looks like progress: wars end, societies become stable, and everything feels orderly.

But the catch is that this “peace” only works by eliminating all other perspectives, whether by persuasion, re-education, or force.

So the core question becomes:

Is unity worth it if it erases diversity of thought?

Into this comes a character who experiences something unusual, he can perceive multiple “truths” at once, like parallel philosophical frameworks that all contain valid pieces of reality. Instead of choosing one, he tries to understand how they might coexist.

This creates what I’d call the “Convergence Problem”:

•If you enforce one truth, you get stability, but you destroy individuality and alternative meaning systems.

•If you allow all truths equally, you preserve freedom, but risk endless conflict and fragmentation.

•If you remove belief entirely, you get apathy and societal collapse.

The idea is that every solution to division creates a different kind of loss.

The character’s role isn’t to pick a side, but to attempt something harder, finding a way for conflicting truths to exist together without one consuming the others.

But that introduces a new tension even freedom itself can lead to conflict, because once people are allowed to choose, they also choose to oppose each other.

So the story explores questions like:

•Is peace something imposed or something negotiated endlessly?

•Can truth exist without being enforced?

•Is conflict a flaw in systems… or an unavoidable feature of free will?

By the end, the idea isn’t that there’s a perfect answer, but that there might be a fourth path: not eliminating conflict, but learning to navigate it without total collapse.

Curious what people think.

Is there actually a realistic way a society could balance unity and freedom at that scale, or does one always win out?

Is the human species even the MC of the simulation?

I thought it would be funny that we could be side characters to the rise of telepathic capybaras.

What are some ways 4D beings can look?

I know it's impossible to imagine.

But I ask this question, because I have a superhero world, where Extraterrestrials exist. And I'm trying my best to make sure Extraterrestrials and Interdimensional Beings don't overlap. With rules like Extraterrestrials still being 3D beings at the end of the day. Therefore they are still going to be limited to the laws of physics. They will still be flesh and blood creatures. Even if their genetic make-up is completely different from humans.

While I'm trying to think outside the box when it comes to Interdimensional Beings thought. Whether they are beings made out of pure energy or just feelings.

So Extraterrestrials are still part of the same physical framework as humans. They evolved somewhere else, but they still obey space, time, biology, causality, mass, energy, and physical structure. Even if they look bizarre, they are still “things” in the normal universe.

While Interdimensional Beings should feel fundamentally incompatible with reality itself.
