50 years later nobody remembers this ship even exists
Famously, nobody knows about the Apollo Moon mission today, because we lost all the records from 60 years ago.
Comment on The problem with sleeper ships
leisesprecher@feddit.org 3 months agoGiven the brittleness of civilization, chances are the backup tapes with the exact flight planes get lost during a thunderstorm and 50 years later nobody remembers this ship even exists.

brittleness of civilization? last i checked civilization has managed to survive 12’000 years since it first came about.

Is that so? Then how is Akadia doing currently? And what’s up with the Hittites? Are the geometry nerds in Egypt still in power?
Civilization as a whole might survive, but civilizations are constantly going under. Just think about how much knowledge was lost during WW2 or after the collapse of the Soviet Union.
There’s exactly two locations in this world still having samples of small pox. Do we know that the location in Russia is still operational? They might as well lost power in 1991 and had their Diesel stolen.

We’ve actually had multiple civilizational collapses. Just because humans survived doesn’t mean the knowledge or civilization did.

I’m still waiting to see civilization start…

50 years is terribly short. 500 maybe.
Also, resolvable. Space beacons, stone tablets, etc.
If you can think of it, so can they.
leisesprecher@feddit.org 3 months ago
And I can think of just as many ways how it can get lost.
Stone tablets break, and how can you even communicate abstract concepts like spacetime coordinates on a slab of stone? There’s a huge debate on how to communicate the simple idea of “danger, don’t dig here” on top of nuclear dumps.
Beacons require enormous amounts of power. We can barely communicate with voyager, and that thing is just outside of our solar system and we know exactly what and where to look for.
Think about hieroglyphs. Those were out in the open for centuries and only through a lucky accident we stumbled upon the Rosetta stone. Otherwise we would have no idea what these weird symbols might mean.

actually it turns out the answer is quite simple, do nothing, you don’t want anybody digging there, and why would anybody dig there if nothing is there.
And if they are capable of digging down to where the waste lies, chances are they’re advanced enough to know about radiation and other relevant risks, so we don’t really have to think about it all that hard.
also voyager 1 was launched in 77, we’re coming up on 50 years, so we could use voyager as a stand in for that specific ship, it’d be weird if we just, sent someone out into space, and didn’t ask any questions, or try to get any follow up information or anything.
The human race is much too nosy for that.

I think you kind of missed my point here.
Think about the infrastructure needed to communicate with Voyager. How many people would be capable of rebuilding it, if it would break? Given something like a major war, or a pandemic, might those people die or simply be shifted to more pressing issues? Since a sleeper ship doesn’t have an active crew, stuff might simply break on their side too. Maybe an asteroid hits the dish.
I’m not arguing that it’s impossible to build technology to keep in touch, I’m arguing that those who do the touching vanish. That’s a different angle.

How would a space beacon be detected by an FTL ship? Unless there’s some sort of weird quantum entanglement communication with some paired exotic material, whatever data (probably a waveform of some type) would be so fractional it is unlikely to be useful or even detectable.
But on top of that, if we still contend with inertia, a ship has to slow down precisely to the velocity of the slower ship or do it multiple times to detect it somewhere and then speed back up again.
But then, we’d also have to figure out why the resources are even worth it to spend and weigh the chances of success and the risks of failure.
Unless the problem is arbitrary for everything involved it is doubtful that regardless of what the future holds for technology that we just wouldn’t pick up the other ship/passengers.

Space beacon can be in our solar system. It only needs to give start date, end point and route.
We can make-up FTL rules. They can use future magic tech to send probes out ever X distance to look for sleeper ship. Or not.

Well if you want to hand wave stuff for a story, sure. The issue with the beacon is a few fold though. So, let’s say they use something close to the speed of light to communicate like a laser and there happens to be no obstructions and the beam is so narrow and powerful it just works. Being even a few light years away just isn’t accurate enough to know exactly where something is going to be in space. Sure, if it travels in an exact straight line (so it’s not near any massive bodies) there’s likely to be some sort of drift, even slightly angular. That’s going to translate into likely at least kilometers in the 10k range between the time it takes the data to be known vs. how many years have already passed from that last bit of data.
Sure though, take away any need for inertia or fuel and yeah, they can just stop somewhere, figure it out and go again and grab it or better yet there’s just some technobabble thing that can instantaneously keep Sol updated in near real-time but also the ship coming to get it. That’s just plot devices for a story though and an author can hand wave away anything they want, so there’s no need to say that if we just talked about a problem in advance, we would just figure it out and make it happen because that only needs to be done in some made-up fantasy if that’s what the author wants to do.
