You must post before you leave

Be nice. Assume others have good intent (within reason).

Use content warnings and/or mark as NSFW when appropriate. Most posts with content warnings likely need to be marked NSFW.

Most 196 posts are memes, shitposts, cute images, or even just recent things that happened, etc. There is no real theme, but try to avoid posts that are very inflammatory, offensive, very low quality, or very "off topic".

Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

I fondly remember watching that movie on TV with my grandparents at their place one summer.

I mean, it was terrifying and might have given me some nightmares since I was pretty young but still, fond memories nonetheless. The movie is just very unsettling, like the horror lies in how alien the whole experience is for the protagonists and it does a great job of encapsulating the weirdness they're going through.

Been many years since I watched it though so it might be actual trash for all I know.

I started it like you as a child but never finished (don't know if my parents had something to do with it) and then recently finished it.

why time travel when there are brutal dictators today? You can always buy a plane ticket.

[–] lauha@lemmy.world 48 points 2 weeks ago (1 children)

Because with time travel you can travel to a time before they are important and under highest security, say when they are 20-years-old and just walking down the street.

I would have a Lovecraftian statue carved out of some sturdy, semi-rare material that can stand the test of time, and bury it in Antarctica tens of thousands of years before homosapiens evolved. Then in present day I would wait...

We can do better than that if we want to abuse a time machine to forge Lovecraftian horror!

I would use my time machine to steal Neil Armstrong's corpse from his funeral and then dump it right at the landing site of Apollo 11. First thing Neil sees when he hops onto the lunar surface? His own aged corpse.

You need it to be propery aged for carbon dating and shit.

How old does carbon need to be before you can legally date it?

At least 18 Billion Years.

I’d go back and save Sergei Korolev from dying in 1966, leading Soviet cosmonauts to land on the moon first and keeping the space race kicking for far far longer.

Yes, I just started watching For All Mankind, what tipped you off?

One head canon I like:

This actually is a good timeline. And our timeline actually has been heavily altered by time travelers! People have actually tried and succeeded at changing the past.

But time travel isn't like in movies. This isn't one of those stories where you go back, change something, and then you come back and everything is a little different. No. In this version of time travel, we get maximum butterfly effect. Going years into the past doesn't just alter history, it completely rewrites it. Go back a hundred years and hang out on a random spot in Antarctica for five minutes, never interacting with another living being? Your presence for that short time will be enough to subtly alter air flows, which will butterfly up to entirely different storms forming in different times and places. Which means that almost everyone born in the last 100 years simply never existed. An entirely new populace is born. No matter how trivial a change you make, any travel beyond a certain length of time into the past results in a complete historical reset.

This is fundamentally not something you can fine-tune. It's not physically possible to go into the past and make a tiny alteration. Every trip is an entirely new spin on the historical roulette wheel. Every trip completely remakes the world.

As such, there's only one practical application of time travel - preventing world-shattering disasters. For example, you could use it to undue a nuclear war. Going back to prevent this apocalypse will result in erasing everyone currently alive, but almost everyone is already dead, so little consequence. Same thing for species-destroying plagues, giant asteroid impacts, etc. Because every trip is a historical reset, it's only useful for scenarios where you're content on just wiping all current people from existence. Even the Holocaust doesn't come remotely close to the level of calamity necessary to justify time travel.

[–] mokus@lemmy.blahaj.zone 6 points 2 weeks ago

You don’t even need humans doing the travel. You just send a 10 kg rock on a one-way trip back and get all the same effects.

[–] SpaceNoodle@lemmy.world 4 points 2 weeks ago (2 children)

No, I was implying that reality simply branched. Specifically when Bowie died, if you're curious.

But back to your hypothesis: if all of the future is rewritten by travel into the past, then the travel to the past shall not have happened. How do you reconcile this paradox?

If I had time travel I would prevent the big bang - or, at least, prevent the universe settling down and becoming friendly to life.

Actually the 10/12/26 massacre seems pretty on pace to happen. It's what kicks off the USA's final decent into authoritarianism and eventual nuclear holocaust.

But yeah, if I had another time machine I'd probably prevent that too.

Too close in time. I'd go back and make Abraham eat lithium... or kill him when he was a child.

[–] birdwing@lemmy.blahaj.zone 6 points 2 weeks ago* (last edited 2 weeks ago)

Abraham was a fucking lunatic for hearing voices and acting on them, trying to murder his own son, and later killing an animal.

You dont need a Time Machine to make better choices today.

[–] BeMoreCareful@lemmy.world 4 points 2 weeks ago

Time travelers are the OG BOFH.

Running around fixing and improving things because: "have to." Viciously cursing any person, place, or thing not apparently and actively helping. Diverting disaster after disaster that they may not may not be the origin of and spending a peculiar amount of time erasing evidence they exist.

[–] dejected_warp_core@lemmy.world 4 points 2 weeks ago

I really feel like a fungible timeline would land us in a similar spot as "you deserved everything that ever happened to you." It would be a kind of hell or purgatory. Let me explain.

To put this succinctly, imagine that our current timeline is "optimal." That with a potentially unlimited number of meddling parties from other times, they have already done the very best they could to "fix" our current timeline. Maybe the job is done, maybe they destroyed their own ability to invent time-travel in the process. Either way, this is all we get. The optimal timeline means that every tragedy is a better outcome than would otherwise have been actively prevented, without causing even bigger tragedies later down the timeline, until more changes would only make things worse.

At the same time, it raises all kinds of thorny questions around the idea of free-will. You might actually have free-will, but the mere existence of powerful beings with the ability to erase your mistakes from history, suggests otherwise.

Reminds me of Capricorn One (1977)
