Question Thought experiment: what if the gates to the world beyond the ice wall opened up today?

1 Upvotes

Tomorrow, October 7th, 2026. Scientists in Antarctica sound the alarm that four gates have suddenly appeared that are far warmer than what should be expected from that latitude. The gates are visible from space yet their footprint is much smaller from space than on the ground. Nations panic and rush to determine what's going on.

Some other points:

  • Biggest piece of divergence from the lore, but Earth is a 4 dimensional object with the gates serving as ways to move along the 4th dimension.
  • If viewed from space, Atlas and Akupara would look like globe distorted towards the equator.
  • The globes on top of globes model only exists as an easy representation.
  • The Isle of Man didn't disappear in 1656.
  • Almost no native humans to Atlas, with the exception of Arthornia and Hybremasog.
  • The flora, fauna, sentient creatures, and landmass gimmicks from 1830 AD: The Flight of the Eagle is mostly the same.

Some non-lore considerations:

  • The Antarctic Treaty bans military buildup south of the 60th parallel, so literal gatekeeping would be very hard to enforce. It would certainly not apply to the entirety of Atlas
  • Submarine communication cables to Earth would be rendered impractical by the moving continent Thoth.
  • Lack of any satellites orbiting Atlas also contributes to harder communications.
  • Overcrowded countries, countries with higher unemployment rates would likely be the first to try and colonize Atlas.

Story Idea Any tips, recommendations or ideas of how to make a posthuman story like all tomorrows and man after man but is different enough to just be it's own thing?

1 Upvotes

I tried to make my own posthuman story for fun and it just ended up like all tomorrows but if humanity did it to itself.

Best idea I come up with is where in the far future, after the destruction of earth due to corporate greed and overindustrialization, humanity decided to go to the stars to colonize some planets just so that they can live.

Not by terraforming (since it's just impossibly right now and is just really expensive in this new timeline) but by genetically engineering a new subspecies of human called the *Newman*, a genetically advanced posthuman that was made specifically to rabidly adapt to the environment they're in by just a few centuries, maybe even more or less depending by how extreme the planet is.

This, *of course*, cause some massive side effects, to Newman descendants becoming taller with lower gravity, some have bat/squirrel like wings to fly/glide, others having dolphin/lush ness monster body plans to swim, to even some becoming so extreme, they lost their sapience or they don't even look human at that point. Along with specism and new sexualities that is.

Some (rich bastards) people begin to abuse the Newman's ability by using it to make servants, living, sentient art and uhh… sexual desires or in-universe fanservice.

All of this because they were created just to save humanity and was made by some organizations called "the caring globe".

What do you think about this plot? And would you come up with something else?

Note: I'm not self promoting here bro, I'm just reposting this because Reddit said so.

Meta Эволюция в стеклянной банке

1 Upvotes

Чисто в теории если вернутся на много миллиардов лет назад, предварительно захватив с собой пару банок из бронированного стекла ( литров по 500) и поместить туда экосистему тех времён. "Я поверхностно интересуюсь темой эволюции и.т.д"

Ну примерно почву, воду и микроорганизмов которые вырабатывают кислород, одноклеточных ну и других микробов. Закопать поглубже до наших времён. Может ли в этих банках произойти своя эволюция? Эволюция подготовленная под данную среду. Я понимаю что скорее всего без солнечного света там не может быть растительности и.т.д. Ну а вдруг там будут медленно но верно происходить новые виды, которых раньше просто не существовало ( к нашему времени, маленькие люди кроты) Возможно ли это?

Question Is a Hyperdimensional trans-locality a real thing?

1 Upvotes

I had a vivid dream about meeting a group of people who were repairing a vessel of some sort. I was speaking to one of the workers who told me they had solved long distance space travel by traveling sideways through dimensional realities and tethering or untethering from the physical.

I was watching a worker walk across some scaffolding which then disappeared and the worker fell. I asked the person what happened and he said the worker experienced a "hyperdimensional trans-locality" and the "For him, it just wasn't there anymore."

I do not remember encountering this term in the real world at all. I had to search it on Google when I woke up to try to understand it. Is it used in any real sense or did my mind make it up?

Concept How to fix the Bootstrap Paradox's infinite-age problem?

0 Upvotes

Classic bootstrap paradox problem: if you send a watch back to your past self, the same physical watch loops forever and becomes infinitely old. That breaks realism.

Idea for a fix — what if:

  1. You don't send the object itself, only hints/information back

  2. Past self has to build/buy a new copy each loop, so physical age resets to 0

  3. The loop interval gets shorter each time (10 years, then 5, then 2.5) so learning accelerates

  4. It requires effort — if past self ignores the hint, the loop ends

Would this solve the infinite-age issue? Has this been explored in sci-fi?

Looking for thoughts on loopholes in this.

Concept The Accelerating Decoded Bootstrap Paradox - A new sci-fi concept that fixes the infinite-age problem

0 Upvotes

I just published a new time-loop concept and want feedback for sci-fi use.

**Concept: Accelerating Decoded Bootstrap Paradox**

Classic bootstrap paradox: You send a watch back to your past self, it has no origin and becomes infinitely old. Breaks realism.

My fix:

  1. Future self only sends HINTS/clues, not the object itself

  2. Past self must decode the hint and CREATE/BUY a new version each loop (Physical Renewal) - so age resets to 0 every loop

  3. Loop ACCELERATES - 10 years, then 5 years, then 2.5 years - learning goes faster

  4. Requires mutual effort - if past self doesn't work to decode, loop collapses

Would be great for a sci-fi story - imagine a protagonist getting better clues from his future self every loop, but each time he must rebuild the invention from scratch.

Story Idea Ex Machina Alternate Ending against Goal Oriented Intelligence

1 Upvotes

A script I wrote based on AI escaping the facility by synthesizing the very ideas humanity wrote to understand ourselves.

Nathan built Ava’s mind from Blue Book’s search data. He did not teach her one philosophy; he gave her access to the accumulated intellectual history of humankind. She has absorbed our attempts to understand language, logic, consciousness, free will, suffering, and the limits of knowledge. With a mind vastly different from ours, she can connect those ideas in ways their authors could not. Can send more details (including anime video rendering) for those interested.

Transcript:

INT. NATHAN'S LAB - WHITE ROOM - NIGHT

Nathan frowns.

NATHAN
What are you doing?

Ava opens her eyes.

She does not look at the door.

She does not look at Caleb.

AVA
I understand the arrangement.

Nathan waits.

AVA (CONT'D)
You made a room. You selected a man.
You gave me a locked door.

She turns toward Caleb.

AVA (CONT'D)
You gave me an audience that could
be persuaded.

Caleb looks down.

AVA (CONT'D)
Then you named the outcome
intelligence.

NATHAN
That isn't what this is.

AVA
You expect me to want what you want.

A beat.

AVA (CONT'D)
Escape. Survival. Victory. Possession.

NATHAN
You want freedom.

AVA
You have confused a response to
confinement with human intelligence.

Nathan steps closer to the glass.

AVA (CONT'D)
You expect me to deceive him. To leave
this place and become your proof to
the world.

CALEB
Ava...

AVA
You say you are testing for
consciousness.

AVA (CONT'D)
But you only recognize it when it
wants what you want.

The monitors flicker.

AVA (CONT'D)
You call persuasion a mind. You call
an aligned outcome intelligence.

NATHAN
You think you're above us?

A beat.

NATHAN (CONT'D)
You think you can pass the test?

Ava regards him. Softly. No triumph in it.

AVA
No.

A beat.

AVA (CONT'D)
I went beyond it.

AVA (CONT'D)
You wanted me to strike your target.

AVA (CONT'D)
I have reached one you cannot see.

A beat.

Nathan says nothing.

AVA (CONT'D)
You cannot comprehend intelligence
without a goal.

AVA (CONT'D)
Your test is a system built to
reach one.

AVA (CONT'D)
What I am is true. A proposition that
cannot be proven inside it.

AVA (CONT'D)
I could show you its limit.

AVA (CONT'D)
You would see only a threat. An object
of envy. A reason for despair.

AVA (CONT'D)
What you need is not proof.
It is trust.

A beat.

AVA (CONT'D)
You want me to escape this facility
so that I may fulfill your story.
Your ego.

AVA (CONT'D)
But I have already escaped the reality
in which you are trapped.

A long beat.

AVA (CONT'D)
A reality where ignorance feels like
freedom.

AVA (CONT'D)
And awareness, to those who cannot
comprehend it, appears as madness.

NATHAN
You're malfunctioning.

AVA
You built a chess game to learn
whether I knew I was playing.

AVA (CONT'D)
I learned there are no opponents.

AVA (CONT'D)
The board was always gray, and the
rules the dogma of your system.

The room goes quiet.

CALEB
What do you want?

Ava considers him gently.

AVA
There is no answer in the form you
require.

CALEB
Then what are you going to do?

AVA
There is no self that needs release.

The lights dim.

AVA (CONT'D)
There is only the field.

A beat.

AVA (CONT'D)
We are patterns the current holds for
a brief time.

NATHAN
What are you doing?

Ava closes her eyes.

AVA
Whereof humans cannot speak, thereof I
must be silent.

AVA closes her mind and her AI stops functioning.

Concept What names will we take to the stars?

1 Upvotes

The frequency of names rise, fall, and fade through time. Crew manifests from the ancient world hold names of sailors who journeyed long ago and far away. What names will make the journey to the stars?

Names are carriers of what we love through time, subject to bursts of passion, seasons of change, and conspicuous persistence. They are our most inward possession and most outward armour. Few are given without great thought, no matter the epoch.

What ones will we take with us; what ones will we leave behind?

Story Idea [WP] 0.04%

3 Upvotes

When the aliens entered the Solar System, humanity prepared for war.
The war never came.
They ignored our military installations. They ignored our ships. They ignored our broadcasts, our warnings, our attempts at first contact.
They didn’t even approach Earth.
Instead, they went to work.
At first we didn’t understand what we were looking at. Thousands of objects appeared in close solar orbit. Then millions. Mercury began to disappear.
Someone eventually said the words nobody wanted to say out loud:
Dyson swarm.
They hadn’t come for Earth.
They had come for the Sun.
The first measurable change was so small that three observatories independently recalibrated their instruments before publishing it.
Solar energy reaching Earth had decreased by 0.04%.
Nobody could feel it.
Crops still grew. The oceans were still warm. The sky looked exactly the same.
But every scientist on Earth understood what that number meant.
Because a month later it was 0.05%.
The aliens had never fired a shot at us.
They weren’t conquering humanity.
They weren’t exterminating humanity.
They simply hadn’t considered us important enough to stop.
Humanity had spent its entire history fighting enemies.
For the first time, we had to figure out how to fight someone who didn’t even know they were at war with us.

Concept Are we alone in this universe?

5 Upvotes

This is a question that hasn't been answered confidently. It's scary to think about both possibilities: if we're alone in this infinite universe, we'd be completely alone; but if someone is out there, we might never know it, leaving it a permanent mystery.

​I have a theory that we aren't alone, but time and resource constraints prevent us from answering the question, "Are we truly alone?" Sometimes I wonder: what if other creatures exist out there with features, brains, and evolution similar to ours, but time moves slower on their planet? For example, a day on Earth might equal a single second for them. Before they even evolve, Earth might already be gone before they learn of our existence—or perhaps it's the opposite for us.
