• that would legitimately be so fucking cool, but I think at those scales we’re actually encroaching on things that truly are physically impossible. If it takes light entire geological eras to move through such a system, any hope of maintaining physical integrity throughout its length is … exceedingly unlikely. Like, at ranges THAT vast, pretty sure the expansion of spacetime itself would rip it open…

    … but i’m still enjoying imagining it :3

    • Does it actually have to maintain physical integrity as a single structure? If it’s not got a vacuum chamber due to relying on the ambient vacuum, then each section of magnets need not physically touch, so the individual components need only use some of the energy from their power source to actively steer themselves into formation rather than rely on material strength to hold together.
