An excerpt from a lecture on Interstellar Travel 101 by professor Rchel Coligera of the University of Dawson Sphere, 3002 PX.
Now I can see that most of you have turned in your pre-course surveys and there was one question that just kept appearing. “Why aren’t we covering wormholes?” Well, I can answer that quickly: Wormholes are obsolete, expensive, and slow.
Yes, slow, I spoke correctly.
”How can that be?” You ask? Well that’s a bit more complicated.
How many of you are from Carrack? Okay, seven of you, good. How about Algernon? Eight, nice. Persephone? Eleven, really? Well, we’ve got quite a few relativist students, that’s no surprise for Interstellar Travel 101.
What would you say if I told you that under the Federation none of you would have left your home system?
At the Federation’s height it’s estimated that less than one in one hundred star systems were within a year’s travel of a wormhole. And most ships took close to a year to reach a wormhole, even the fastest ships of the Federation era took a month to travel from an inhabitable planet to the Oort Cloud where wormholes could be safely emplaced. Travel from systems without wormholes often took decades. You interstellar students are aware that by the time you return home your siblings and classmates will be middle-aged grandparents, unless they were fortunate enough to have access to leukosynths. But if you’d taken a wormhole to Alpha Centauri, they’d be long dead.
Sure, we could combine modern singularity drives with wormhole travel, but why would we? The wormhole network is gone, with a few rare exceptions. And it would be far too expensive to try and rebuild it.
You might have heard that the micro-singularities powering a 1,000-hydro-ton liner consumed a small planetoid, but the mass consumed to make transversable wormholes is measured in stars. We can only guess how many brown dwarfs were sucked up into Proxima Centauri’s StarForge. Just one brown dwarf could support a population of billions, as many peripheral polities have discovered after obtaining singularity drives, or build a fleet of thousands.
Due to this expense the StarForge took the better part of a century to produce the first traversable wormhole. Even in the Federation’s final century we only have records of four, maybe five new wormholes opening. This was one reason why 90% of all wormholes connected to the Alpha Centauri system, and collapsed when Sol went nova.
So, the better question is, why did the Federation bother with wormholes at all? Why didn’t they just build stellar swarms like the one you’re all sitting inside? Two words: Dispersal and security.
The Core Worlds were colonized by refugees from Sol after the Destroyers scrubbed the system of life. When the Federation formed they knew that the only way they could survive as a clade was to keep a low profile, thus they adopted a policy of spreading parahumanity thin across the stars. Since the Destroyers were apparently destroyed, the university has detected five other stellar swarms in the past two centuries, including around Alpha Centauri B, Tau Ceti, and Epsilon Eridani; the Federation’s Core Worlds.
As for the second point, the Federation could not tolerate competition. You might have heard of a “Pax Federaci” but I’m going to tell you right now that entire concept is revisionist bullshit. The university’s archaeological expeditions have uncovered sizable evidence that “deportations” to Outworlds were far more common than the records would indicate. Helped, naturally, by the Federation’s policy of erasing all evidence of the deported’s existence in the name of “memetic containment.” We have even discovered a few Outworlds that appear to have started as fully Federated colonies, only to be bombed back to the Stone Age later on.
So, yeah, we might be islands in space and time separated by years, but we’re more connected than ever.
