What if the measurement device in the double slit experiment were a light year away?

In the famous double slit experiment, setting up a measurement device that watches which slit an electron passes through changes the eventual outcome on the screen, causing the wave function to collapse.

If the measurement device were a light year away and were precise enough to "zoom in" and see which slit the electrons went through, what would happen on the final screen?

Surely, if the measurement device were off, then the electrons would behave like waves and not particles. An interference pattern would appear on the final screen as there is no observer. On the other hand, if someone a light year away turned on the measurement device, this far-away person (and the measurement device) wouldn't know which slit the electrons went through until a year later. And, the electrons going through the slits wouldn't "know" they are being observed because no information (ie the measurement device turning on) can travel faster than the speed of light.

Youtube alternative solution
  • If I may offer a new way to think about things - YouTube ads support creators by allowing them to make a living making their videos. It's quite different than Facebook, Instagram, and Reddit, where a company is just hosting and monetizing people discussing and sharing things with each other. If you want to see good content, YouTube decentralized alternatives will really only take off if there is some sort of crowd funding going to creators. Which would most likely take the form of a subscription. And...that is essentially YouTube premium anyway. And I might add that I've had YouTube premium for years and it's my favorite subscription I have across the entire internet.

    For example, on my profile picture. Find them on Coolbuddy or some other site and save as a webp.

    I'm on my fourth playthrough of Link's Awakening Remake for the Switch
  • The music in the credits was unbelievable (and the music throughout of course)

  • I'm on my fourth playthrough of Link's Awakening Remake for the Switch
  • I would LOVE to see a feature film in that art style (at the end).

  • I'm on my fourth playthrough of Link's Awakening Remake for the Switch

    This is such a great all-around Zelda game and isn't a huge time commitment either. It's very linear but there's plenty of random mini games and shops to explore. It also is a very special and unique Nintendo game and incorporates an early looking version of Kirby and has chain chomps from Mario. The art direction is "toy style" and it's incredibly polished. It's really one of those remakes where they didn't cut any corners.

    Meta cancels Quest Pro, stops development of Quest Pro 2 | ZDNET
  • Maybe they realized that Apple's is so much more premium that whoever would buy the Quest Pro would instead by the Apple Headset.

  • Wikipedia is amazing
  • Have you heard of Obsidian? It's basically a note-taking/journaling app that allows you to link entries to other entries similar to Wikipedia. Overtime you create a wiki of your mind and experiences. It's also free and saves your files in markdown.

Additionally, communities you are not subscribed to show up in the home feed - you would need to block such communities to not see content from them. You could make the argument that one should really just browse communities you're interested in without viewing the home page, which is fair. However, take technology for example.

    What are you playing this weekend? 2023-07-15
  • BOTW and TOTK are both 30 FPS - unless you played it on PC or Steamdeck emulated or something

  • Age Reversal Breakthrough: Harvard/MIT Discovery Could Enable Whole-Body Rejuvenation
  • With term limits of course. Idk there could be a possibility that they'd take the planet seriously though as they'd be around to see the consequences of environmental policy

  • I wonder what people will look like in their reverse-puberty stage.

  • Skyward Sword HD! The visuals and dungeons are so fun. Also, it turns out it's the only Zelda game that's HD and 60FPS. I hadn't realized this before. I really hope they remake other Zeldas.

  • I don’t think depressing content is a meme

    There’s a subgenre of memes that was super popular on Reddit which was basically just depressing thoughts and information packed into a meme format. These memes don’t really add anything of value to any platform in my opinion and usually just make the reader feel bad, either because it highlights something negative, or because it is dystopian. Here is an example: https://lemmy.world/post/1405826?scrollToComments=true

    It’s in a meme format, but what’s the point? Opponents of this thought process tend to say that we should let upvotes and downvotes decide - because if something is upvoted, then people must like it. The problem is negative emotions create more engagement on average, so upvotes aren’t an accurate reflection of what content is good.

    This is aging incredibly well.
  • I might be pretty ignorant here but what is so proprietary about Twitter/Threads? It just lets people make public status updates and share photos. Unless they literally used the same lines of code, how is it infringement and trade secrets?

  • The first flying car, 'Model A,' approved by the FAA and it's 100% electric
  • But there’s more dimensions to swerve in to avoid accidents. Before you could only swerve on a flat plane /s

  • If beauty is tightly associated with facial symmetry, then why doesn’t everyone have their hair part down the middle?

    Edit: to clarify, I know that many short hair styles don’t have a part at all. Mostly talking about people with hair long enough to have one. I find it interesting that many studies conclude that beauty is tightly correlated with how symmetrical someone’s face is. However, many haircuts and hair styles are asymmetrical, including any style with the part off-center (very common for both male and female hair styles). Not just that, but we really like the way these haircuts and styles look too. It makes me wonder why one’s perception of beauty might not take into account the symmetry of one’s hair. I don’t have an opinion on what looks better, symmetrical vs not symmetrical as I think it depends on the person and what suits them. I am wondering if anyone else has thought about this.

    Why does Lemmy feel so fresh compared to Reddit?

    As a long time Reddit user, there's something about Lemmy and the fediverse that feels really refreshing and new. I think it has to do with a few things...

    1. People are more respectful of each other and interested in discussion and being social.
    2. Less trolls (users are probably older?)
    3. Due to it not being absolutely huge, I feel like people will actually see my posts and comments instead of being lost in a sea of content. I suppose once Lemmy grows this will change, however the cool thing about the fediverse are the new servers. So you can stick to the server when you want smaller community discussion and go to "all" when you want more populated threads.
    4. The clean UI feels refreshing and clean, almost like the early internet.

    What have you noticed? Do you find it refreshing too?

    I made the mistake of checking Reddit (using my last few days of Apollo) and came across a complaint about Lemmy that flabbergasted me
  • I think Lemmy could use some more ads. I feel like I don't have enough material things, and I don't know what to buy. /s

  • Should we start crossposting content from Reddit?
  • I agree, I'm the same way.
