/cyb/ - Cyberpunk Fiction and Fact

Cyberpunk is the idea that technology will condemn us to a future of totalitarian nightmares here you can discuss recent events and how technology has been used to facilitate greater control by the elites, or works of fiction

BIRCH WORLDS - THE ULTIMATE SPACE SCIENCE THING

Today I learned about Birch Worlds for the first time.
They say that if a Black Hole is large enough, the gravity just above its event horizon will be about equal to earth's gravity.
Therefore, one can build a fucking huge artificial shell-world planet built around this black hole to exploit the earthlike gravity at the extreme planet size.
Because normally, a bigger planet means more gravity.
But black holes can piss all over that.
"They allow for normal gravity at extreme planet sizes", says the guy who told me about these.
The bigger the black hole is, the larger the shell around it can be.
"A theoretically infinite number of people could exist on a massive artificial planet built around a sufficiently large black hole, especially if a system of multiple layers of false world is built into the false planet, since there would be little meaningful difference in the gravity between one layer and another" says the birch world fans.
They say that on such a planet, the world would be so large that the world would seem flat to a normal person on the ground. Incomprehensibly large and utterly flat. A single lifetime of endless air travel in a single direction couldn't take you to where you started.
There's only one way to make this even more intense: Add a method for this colossal artificial world to generate energy from the black hole it's built around, letting it become self-sufficient.
Literally the only downside (besides standard theoretical science "bruh what's stopping the fake world from moving too much to one side and getting eaten by the black hole" stuff) is that trying to get off this world would be a bitch. Achieving escape velocity would be tricky.
Still, is that sick or what? A fucking huge theoretical artificial earthlike world that exploits a black hole to gain earthlike gravity.

I know this board is meant for doom-and-gloom science that could create a dystopia, but where else could I post this? The self-improvement board? The sports and shitposting board? The front page, despite its lack of relevance to politics or ponies?

Then again on such a world, long-distance communication between people would be a pain in the ass. FTL communication would be needed for any group to control the whole planet and that's probably never happening. The world's governors would be restricted to governing local areas. The word of a ruler and his rule would end at places his word and soldiers can't travel to in time.

wait I probably need to make this sufficiently grimdark. uh...

Imagine if a corrupt government imprisoned dissenters, removed their brains and put them in self-sustaining cyber-jars rigged to keep the brain alive and simulate pain in the brain, and then stored these jars on an incomprehensibly large Birch World.

There would be so much motherfucking room. There could be millions of tortured brains. Billions. Fuckillions. It would be horrible.

It would be awesome.
A book or sci-fi work about a constantly expanding birch world. Where over time the world is being pulled apart for new populations.
A real incredible thing to have in any kind of tech is time-space manipulation.
Technically it is possible to achieve time travel as well, but the raw material and construction would exhaust the entire universe.

Is this what you are talking about?

Yeah thats where i learned about it
The stellaris mod
though personally I think a galaxy wide megaslice ringworld thing is better, since it is galaxy wide. That's probably bigger than a reallybigblack hole.

This is only theoretically possible, in practicality, the mass of the structure itself would generate its own gravity and rip itself apart with the slightest of movements. You'd need a super light, super strong material to build it, and you'd need more material than a single galaxy could even provide. Say you could construct it out of pure hydrogen, the most common element in the universe, there wouldn't be enough in this entire galaxy to do it.

Fuck, you're probably right.
I bet a system of normal-ass but huge space stations orbiting around real suns would be more efficient.
