    It’s a good argument against trying sleeper/generation ships.

    In practice, though, the actual sleepers would be so happy to arrive to find a nice McDonalds and a charming small town instead of shuttling down into the middle of uninhabited Arrakis with a 3D printer and a prayer.

      As a guy who sometimes gets told “Hey, don’t worry about that work you had to do, you can skip it”, hard agree. No better feeling in the world. And after thinking you’d have to build a whole civilisation from scratch? Yeah, nah, sign me up for the generation sleeper ship please.

        Imagine if a lost Spanish armada finally arrived at Florida, centuries late, musket-wielding conquistadors raiding a coastal naval academy while a prominent political VIP was giving a speech, taking them hostage like Hernán Cortés did with Moctezuma II (Aztec Empire) or Francisco Pizarro with Atahualpa (Inca Empire).

        Why waste your hate on it? I haven’t had McDonald’s in over 25 years now and it causes me no problems to just go past one and not think about it

    If FTL is impossible (as is likely the case) there is a point where a better ship can’t catch up, even if its going like 0.9c.

    Worse: your sleeper ship arrives at what should be a pristine planet. But FTL capable ships beat you there. And they ruined the planet over a few thousand years. And now they’re sending out refugee ships of their own.

    It’s a neat idea from a sci-fi perspective, but when you think about the most efficient forms of space propulsion (slingshots around large gravity wells) I’m not sure how we’ll manage to do much better.

    Either you catch up to someone before they leave the solar system or you’re just going to shorten the time needed to reach their terminal velocity.

    There’s a diminishing return as you approach the speed of light, and FTL travel isn’t exactly a trivial hurdle.

      You could say that the amount of time it would take for an interstellar trip at non-FTL speeds is also not exactly trivial.

      We can sort of try to imagine how technology could develop in tens of thousands of years, but… not really.

        We can sort of try to imagine how technology could develop in tens of thousands of years, but… not really.

        To some extent, I think we’ve become blinded by the progress we’ve made in the last century relative to the progress we made in the millennium before that. For the vast majority of our 10,000 years of human civilization, life was of relatively uniform technological variance. We’re in a big uptick of progress in this moment, but eventually (I’d argue very soon) we’re going to exhaust the natural limits of our surroundings and the advances of technology will run up against the limits of our material conditions.

        Then we very easily could be in a world where the modern day “high tech” nature is the baseline for decades, perhaps even centuries or millennia. Also, very possible we dip into a Dark Age. We’ve done it before. And its not as though this degree of manufacturing infrastructure is cheap or easy to maintain indefinitely.

      It’s stolen from Elite: Dangerous. You can find a few of those colony ships drifting around deep space, but you’re warned with heavy penalties to not interact with them, for this exact reason.

    There was a sci-novel about that, I don’t remember who wrote it. Essentially, after FTL got invented they caught up with generation ships and retro-fitted them with FTL drives; overall message of the story was that humans are a valuable resource and they should not be discarded lightly, especially in a mission to seed the galaxy.

    Or you arrive to find the civilization has had time to collapse and given way to the rise of damned dirty apes.

    Such a plot device has been used in every sci-fi universe I’ve been interested in. It’s not even funny.

      Galaxy’s Edge did a pretty cool take on this with the billionaires who fled a dying earth and became the Savages who lost their minds in the deep black. The remaining humans on earth built FTL like 20 years after they left and had like 3000 years to establish a galaxy wide Republic before they encountered the insane Savages who spent all that time experimenting on their own and trying to become actual gods.

    I’m surprised this isn’t the central plot device of some blockbuster property.

    Imagine trying to escape humanity only to end up being surrounded by humans again. Nightmare fuel.
