    Hi, just signed up after watching the u tube end of the month podcast. Have watched most if not all of Isaacs weekly u tube shows I would like to complement him on a great shows and thank him for doing all the research I’m to lazy to do myself. I would also like to ask him if he is aware of the latest breakthrough by General Atomics fusion research and would like his thoughts on it and hopefully the near adoption of fusion power.

    Hi folks. I'm a big fan of sci-fi, both hard and soft. I was lead here by the Isaac Arthur YouTube channel, which has given me great deal of inspiration for my writings. I hope to one day be published, but no luck so far. I am hoping this site will give me a place to ask questions, bounce ideas off others, and in general confirm or disprove whether something is plausible or not. I also play a lot of sci-fi rpg's and like to at least try to stay realistic for the settings I design.

    Hi, all! I'm a human, like probably most of you, but looking forward to the day when I can be whatever I want to be. To pass the time, I'm worldbuilding some far-future kitchen sink with ancient, clarketech megastructures and transapient-engineered life as a focus, and I'm always on the lookout for new ways to think of such things, and contemplate what life might look like there. I've been especially interested in how those environments would be maintained, and so I'm extra excited to see Isaac Arthur's next week's video on Megastructure Maintenance. It's hard to remember when or how, but if I were to guess, I'd imagine I found his channel through the Atomic Rockets website. To realize this project, I am kind-of putting together a comic book, kind-of writing some gibberish on scraps of paper, totally conlanging some several somethings, sometimes studying how to make interactive software, often designing characters, cool outfits, and powers and places like some sort of Game Master fashionista, and always cataloguing and developing vague concepts and rhythms in my head, as I strive to come to some sort of auctorial nirvana where creation and perception merge to form something that always existed, but never was--breath

    But it's been a rough last year and I've had a writers' block that would make an old geezer's piss look like the biblical flood, despite having the greatest cohesion and versimilitude that I've ever yet had in this world. Honestly, it was a long winter and a late frost, and I think the tree just didn't bloom this year.

    Outside of the purely worldbuilding, but as kind of a supplement, I spend most of my time studying--lately I've been focusing on mandarin chinese and japanese to broaden my ability to communicate and think outside the box, with some basic arithmetic in dozenal. I'm just an obsessed eccentric with little to speak of in terms of personal life beyond my educational and auctorial pursuits.

    Está un placer de conocer ustedes.

    P.S., My aesthetic and thematic inspirations revolve around that brief period of 90's videogames that look like Jedi Knight Dark Forces II, Katsuhiro Otomo's AKIRA, the first two Alien movies, Peter Hyams' 1981 Outland, Ghost in the Shell (Shirow's manga and the anime adaptations--I found enjoyment of Scarlett Johannson's performance of The Major impossible, and Batou's performance--who was my favorite character from SAC--downright cringeworthy), and pretty much everything by Nihei Tsutomu, and I'd be really glad to talk about that niche and media of it, or whatever gives you that sense of otherworldly nostalgia, personally.

    Hiya LightspeedLife. I think you'll find many like-minded people here - feel free to browse and start conversations. Unfortunately we don't have a lot of traffic these days - but poking at a thread should resurrect it.

    As for your writers block - I totally sympathize with you - I've had a persistent case of it for about a year now and it refuses to move. Maybe learning Mandarin will help me out XD.

  • Aug. 11, 2019, 7:09 a.m.

    If you did, I'd be happy to practice with you!

    I'm sure that as the channel grows and people from the forums start creating more media, traffic will grow. The site is still new-ish, right? We may be niche, but even a tiny fraction of the world's people is still a great number. We may all find our way here, eventually.

    The forum was established about 5 months ago. And yes, I hope that this forum will attract more users and content. The I'd say that the subject matter certainly has its number of followers, since it covers a broad range of subjects including STEM sciences, sci-fi and world-building. Unfortunately, Discord steals a lot of steam from a lot of forums.

    As for learning a new language, I doubt my schedule could support such a challenge. But it is certainly on my list - a Chinese language in my repertoire would be very useful!

  • Aug. 16, 2019, 3:29 p.m.

    Hello everyone i am very interested in science fiction and Isaac's YouTube is brilliant i also love pbs space time and anything science related to be honest. i wont lie i have more of a pop science understanding of things and my math is a low standard right now ( something i aim to improve ) . but science has always been my favorite subject to think about and discuss.

  • Aug. 17, 2019, 12:48 a.m.

    Hello, I wanted to introduce myself on the forum. I went to school for music but ended up in an STEM field for an occupation, as a QA Analyst/Test Associate in the gaming industry. I really enjoy Isaac's approach to space travel and futurism and wanted to join the conversation here.

  • Aug. 23, 2019, 1:35 p.m.

    I'm a big fan of the show and the 200th episode on impossible things really made me think... one of my favorite games is trying to describe how impossible things might be possible. ...so yeah, I'm also a huge sci-fi fan. 99% of the time I already have the book of the month

    My favorite book is actually "Guidance Withdrawal" - It's about what it means to be human and to strive to be a better person in a far future universe dominated by superintelligent minds of every possible variety and scale. Do you join a collective mind, integrate with AI, or just strive to be a better 'baseline human'?

    The main reason I'm here to engage in cosmological debates. - Issac said there are facts that are not open to interpretation because they are logically true, and objecting to logic is essentially dumb. I get that, and I know the feeling, but history has taught us over and over to expect our perception of the universe to get flipped upside down at any time. We know there's some logical truth that can't possibly be reinterpreted, and then, surprise! we found out we had been looking at the evidence wrong. Don't worry, I have a high reverence for observational evidence. Any talk of time-travel or ghosts gets dumped in my 'brain in a computer' where anything is possible category. I mean, obviously I've tried to imagine some version of the universe where every current 'state' of the universe could be preserved and remains accessible, like a time landscape instead of a line, but there's essentially zero evidence so I don't give it a lot of consideration. There's even some great sci-fi that describes history as if it were locked in an extrademinsional ice-core and we could melt our way back for a time reset! At that point, a database restore operation sounds more plausible, but it's still fun.

    Anyway, I know it's bad form to introduce ones self with heretical claims, but I think conservative forces are an illusion, and the natural forces will run out of power as the state of the universe changes. Crazy right? It's deeper than just the Big Rip. I really hope to find someone here who's interested in saying, 'Oh yeah, how?' - in the appropriate forum of course!

    HI, W5JN here!

    I (thankfully) found SFIA while searching around on YouTube....the very best use of my time this year!

    Dave, W5JN

    Hello, I am new to the forum. I discovered the YouTube channel a couple months ago as I was doing research. I am a science fiction author and have found much of you content, interesting, or at least entertaining if not enlightening. It has helped me do lots of world building and answer questions no one has asked. (At least not yet anyway.) I would like to establish a working relationship in the future as my book gets nearer to it's launch date, so that I may use your content as a reference. I plan on starting a channel where I will be discussing these same topics, but only within the scope of the universe I am writing.

  • Sept. 2, 2019, 5:22 a.m.

    Just discovered Issac's videos a few days ago while trying to anticipate the practical approaches of humanity's solar system expansion through the 21st-22nd centuries. Ultimately, I'd like to shape my career to help accelerate that progress, so it helps to have a such a great roadmap in the form of Outward Bound / Upward Bound series!

    I started poking through the About section to figure out if Issac was a one-man army producing all these, but was pleasantly surprised to find a whole production team and budding community! SFIA is seriously awesome stuff, unparalleled in depth of niche info, fun video productions (with great musical selection!), and humble, thoughtful, presentation. I thought it was all Isaac, but hats off to the production team for all the awesomeness!

  • Sept. 5, 2019, 10:12 p.m.

    I run a science meetup group in Houston, TX. I would like to use an SFIA youtube video at one of our meetings. Is there a problem with that? Also, are there any subscribers in the Houston area that feel comfortable making a presentation on space elevators?

  • Sept. 12, 2019, 5:26 a.m.


    I am a researcher in positronium physics. I basically live in my lab in California but dream about Mars :)

    Watching Issac Arthur's YouTube videos lead me here. As an eternal fan of hard sci-fi, I've always been motivated to pursue research in the sciences through the excitement I get from reading about speculative ideas. And now I have an extension of that in the form of Arthur's site and videos. Though, as Carl Sagan once said, "one should be careful to distinguish speculation from fact", I think it is ok to let the mind feast on amazing ideas!

    It's time for my nightly serving...


  • Sept. 20, 2019, 6:22 p.m.

    Hi guys, just registered and figured I'd come say hello and thank SFIA for the quality content of weekly YouTube vids.
    Now, whether this be an episode idea or even if someone could point me toward a book where this topic has been elaborated on...

    I'm intrigued as to what living on a planet or habitat with a trillion or trillions of people would look like in relation with trying to keep up with current trends or maybe being on the forefront of innovation?

    Rapid pace change in today's world seems a lot more prevalent then any other (if not nearly all combined) previous era's of human history.

    The number of new ideas and their implementation compounded with more new ideas on top of the previous ideas would be epic in comparison to today's standards.

    Even if the technology itself isn't advancing necessarily all that fast, the element of wanting to do something new and the subsequent trends that follow would be hard to stifle so it seems?

    Decide to take a little hour nap and wake up with 1600 new SFIA episodes you have to scramble to catch up on! 🙉

    Hi, new comer to the forum but i've been a subscriber since the early days. I've had a few thoughts on some subjects and thought this may be the best place to discuss them and see where it leads.

  • Sept. 26, 2019, 6:52 p.m.

    Hello everyone!
    I'm a long-time SFIA subscriber, science enthusiast (mainly astrophysics and cognitive science) and I'm wildly interested in futurism.
    After a long absence at the forums I decided to register. Thanks to Isaac I'm just about finishing Alastair Reynold's Inhibitor trilogy, which has been a great aid coming out of depression.

    I came here for inspiration regarding a new sci-fi novel project of mine, but also for general mental stimulation and fascination. Excited to be here for the ride with all of you.

    Have a wonderful day

    Hey what's up guys, I'm a Security Engineer. But I also love space and science in general. Just looking for a place with like minded people...
