  • It’s been one of three things for me:

    • Like having a cool friend you see a lot. Good memories, but never a relationship that lasted.
    • Someone working out how to twist my own mind against me, controlling me for their own gain and never actually understanding that a relationship isn’t a transaction. (and hopefully that one isn’t stalking me on lemmy again, otherwise I or one of my friends will get harassed and I’ll be filling out an intervention order)
    • The most beautiful thing that I didn’t know was possible, I thought I’d been happy before but when you meet the right person you really do just click and life becomes worth living. Never felt so good about myself as I did then, just hurt all the more to lose it so suddenly. I’ve written a lot about others I’ve only met briefly, songs about people who’d never think of me that way, but when it’s true love I just can’t. I don’t think anything I can say could really capture that. There just isn’t enough poetry in the world to describe how magical it is to look up at a pair of beautiful brown eyes swimming in a field of stars and hearing them say “I love you” for the first time.



  • I really need to learn a healthy coping mechanism, I’m getting a bit sick of crying every night and ruining my physical health in response (not self harm, it’s complicated)…

    Other than that, preparing for a high chance of being arrested because the NSW supreme court thinks it’s okay to erode our right to protest. I’m slightly scared I’ll have no accommodation and have to sleep rough for a week or so due to other permits not being approved, but I’m sure I’ll manage, urban camping is always an option.

    Got my parents on board to make some donations to help out those in the states get to safety, so that’s some good news.


  • I’ve had a lot of these experiences, and it’s been pretty hard, I’ve even had the exact same experience with The Owl House actually.

    Honestly I’ve been dealing with it by working on myself, I’m slowly becoming someone I like to be and feeling more confident, largely through diy fashion, but also just by getting involved in stuff I’m passionate about. Over time the envy has begun to fade because I’m feeling more and more like I have my own identity and I like who I am now.

    I have no idea if it’s even remotely the same for you, but once I stopped feeling generic, things got a lot better. These days I look in the mirror and I see the punk I am, instead of a struggling mess with no direction, and that makes me feel secure about myself. It’s still really crazy to me that I feel more real than ever because of a pair of pants made of dental floss and dirt.




  • I’ve only ever done QFT in curved spacetime, but I don’t see any reason why you couldn’t do EM, it’ll be a vaguely similar process. I never actually dealt with any scenarios where the curvature was that extreme, and QFT in a curved background is kinda bizarre and doesn’t always require one to consider the specific trajectories, though you definitely can especially if you’re doing some quantum teleportation stuff. In my area it’s simpler to ignore QED and to just consider a massless scalar field, this gives you plenty of information about what photons do without worrying about polarisations and electrons.

    It’s been a long time since I did any reading on the geometric optics approximation (in the context of GR this is the formal name for light travelling on null geodesics), but for the most part it’s not something you have to consider, even outside of black holes the curvature tends to be pretty tame (that’s why you can comfortably fall into one in sci-fi), so unfortunately I don’t know of any phenomena (in GR) where it’s important. QFT in curved spacetime generally requires you to stay away from large curvatures, otherwise you start entering into the territory of quantum gravity for which there is no accepted theory.

    Outside of GR, it breaks down quite regularly, including I believe, for the classic double slit experiment.

    Edit: Another really cool fact about black holes is that even when you’ve got really large wavelengths, it often doesn’t matter because they get blue shifted to smaller wavelengths once you get close to be horizon.
