Subspace is the answer of course!

    This is why Jesus invented ‘two cans and a piece of string’.

    Dammit, I’m not even a trained physicist but I still have to do all the thinking around here.

      Jesus Christ, why’d this get so downvoted? Do people not get sarcasm?

          It’s mechanical, so each atom is pushing against the ones immediately next to it, and so on, until other end moves.

          It would be interesting to work out how much a metal bar the length of our solar system would compress when you push it…

      What’s the propagation speed of vibrations through carbon nantubes? I’ve done no math or experiments but back up this startup tech 100%. I pull on it at Alpha Centauri, it instantaneously pulls a receiver at Sol. I’d say a vat of liquid nylon with a thread pulled and dragged but that sounds sticky.

      Edit /s no one is towing a rope

          Does a lower frequency signal travel the same speed? 1hz? I suppose it would be the same because the tether would have immense mass over it’s length. So even though I’m picturing an impractically long tether moving as one solid length to tap slow morse code, the mass would be unfathomably high and therefore inducing significant stretch. That’s without getting into vibration kinetic energy being lost to heat along the way

          I’m obviously not genuinely proposing this. It’s just a brain exercise.

        Now I’m imagining spider-ships traversing the galaxy making strings of filament behind them, connecting the galaxy in a vast web of communication lines.
