I came to SE WB while I was researching about space radiators for my sci-fi. I don't remember where exactly I found an answer to my question (Maybe? Idr) but I stunned with this site. You all looks like amazing.
I'm trying make this story as accurate as possible, start it years ago as way to teach some simple concepts to my children and the thing grow up since then:
In the year 2240 Humankind is in a time of reasonable peace and prosperity, the last giant calamity was depression in 2030-2050. After it, our species developed fusion nuclear reactors, organized political institutions in city-states and an unified global Parliament, built space elevators and a geostationary ring like the sequence in final chapter of The Fountains of Paradise in c. 2100. Then they moved all industry to orbit, built efficient space stations by the ring, similar with O'Neill cylinders, inhabited like small towns. Some of those stations release from the ring after disagreements with Earth government and call themselves as Wanderers.
Plans to terraform and colonize Mars and Venus are put in action and the Martian colonization starts before they even complete a decent atmosphere. Between years 2120 and 2240 the red planet population is raised from 50 persons to 960 million inhabitants. They built a geostationary ring and space elevators near/on Mars too.
Spaceships still use fission nuclear reactors since miniaturization of fusion reactors has made slow progress. With promising new fusion reactors comes the development of the constant acceleration drives. By 2240, space mining has cleared almost all asteroids in near earth orbit. Wanderers move more and more away from Earth and after Mars and are base themselves in the asteroid belt and separate into several clans. Some clans have their stations orbiting major asteroids (Psyche, Juno, Hygiea...) while Earth rule in others (Ceres and Vesta) and giant space mining companies own others (Pallas, Nemesis and small others).
Everything is going fine, building the narrative and writing well are more of a challenge (in Portuguese! To English is another long road) than building all the background, but one detail still bother me: years ago I read about quantum entanglement I thought was possible use to communication FTL. Shortly after that, I figured out that it really doesn't. I am looking for different options and the only one that seems possible is wormholes.
This bring one new set of challenges: how build a wormhole is main one. This Kurzgesagt video give some glimpses. I hear about Clarke's The Light of Other Days but still can't look for and not sure if worth in this purpose.
Building a gravitational well and establishing the wormhole with negative matter made in vacuum still seems ok in the scenario. However with some questions, lets say, engineering questions I would like some help:
1. What would be the size of wormhole to information only? This answer of Galactus Renan its a good start.
2.Once you have the one stable gravitation well opened with two mouths, how you would split it? Or in the other way, how you would take each mouth to their designated point?
