    Hi everyone. I'm a new member, just looking for a bit of intellectual stimulation from time to time.

    Welcome Chuck, its great to have you here. What topics are you interested in discussing/pursuing?

  • April 27, 2019, 9:22 a.m.

    Well I'm not chuck, but to answer the question above, Fermi Paradox and alien stuff is big for me. Where are those buggers?

    I'll put my money on klendathu

    Hmm, fair enough, but I'd much rather wager on 42 :P.

    Anything from futurism to afterlife to the paranormal.

    With ‘paranormal’ do you mean non-Gaussian?

  • May 2, 2019, 8:05 a.m.

    I would say that the ideas of an "afterlife" and those of the paranormal belong together in the same field: pseudoscience. So far as we know, research into these types of phenomena have resulted in very little. Those who say otherwise are often guilty of a multitude of cognitive biases toward their research. It is certainly a fun subject to discuss and theorize about, but ultimately any analysis of it other then passe debunking is futile due to lack of evidence.

    Hello guys and gals, I am Sam, I have been following SFIA since issac's youtube channel had only 30k subs. I read a lot of about science and contemplation is kind of a hobby.
    Do guide me on how to join conversations here. Thanks.

  • May 12, 2019, 1:27 a.m.

    Welcome Sam! Long time fan indeed. The website is still very new and lightly populated, though we have several planned features for future updates. However, conversation wise, jump in to any thread you are interested in or create one if its not already created. What kinds of topics do you enjoy researching/conversating about?

    I enjoy gravity, space mining, energy farming/storage myself

    Hello everyone. I fell in love with the channel since Isaac Arthur's explanation of tidal locking. I've joined the SFIA reddit a couple of weeks ago. i'm a physics student who'd like to contribute by helping with: coming up with new subjects or brainstorming them. Where should i go?

    Hello, I'd like to make some animation. What are the video preferences, and what's the best way to get rendered video to the studio?

  • May 13, 2019, 7:45 p.m.

    The SFIA Discord has a section for ideas pertaining to new ideas/episodes. It would also be a great place to look if you are interested in joining the production team.
    Here is an invite link to the discord,

    I would recommend joining the SFIA discord as well as Luca would be the one you would want to talk about regarding video/audio. More thank likely he will want you to join the production team for the sharing/feedback of such content.

    First off thanks for the membership! I'll start by saying I have no formal experience in any STEM fields but I am none the less an avid follower of science and technology. My addiction to space has grown in recent years culminating in a trip to Florida where my wife and I spent a day at the Kennedy Space Center. Needless to say I was completely floored by the experience and it has made a lasting impression on my life. After that trip I can confidently say my life's goal has been to enter the space industry in anyway possible. Seeing the impact of past and present pioneers in the industry is both humbling and inspiring. My main focus is to absorb as much information as possible and network with as many like minded people as I can find. Although my scientific knowledge is limited I do have mental acuity and hopefully this it is enough to participate in the SFIA community. I am currently in a full time career however I'd be eager to volunteer my time to help grow the channel and community (if possible). As for my personal interests I've become very partial to two specific topics, Fission Fragment (or "Dusty Plasma" rockets), and Space Habitation technology utilizing lunar regolith accompanied with artificial gravity (centrifugal). The former has been induced by an idea to re purpose reactor to produce larger quantities of Americium 242m for use in high speed space transportation. Based on the research I've done it would require a substantial investment in nuclear infrastructure to realize considering 242m's difficulty to isolate, which as I understand stems from its excellent cross section and low critical mass (doesn't survive long in a reactor). The later is a more practical "short" term goal ( no radioactive exhaust, superconductors, or treaty violations) which involves collecting lunar/martian regolith for use as a construction materiel in space. The full spectrum of my idea is hard to convey over a keyboard so hopefully in the future I'll be able to capture someones attention in a face to face or voice chat (like I said I'm not a degree holder). I try my best to stay ground and not get carried away although my imagination can be rabid. Well that's about it from me, once again thank for the invite.

    Hi everyone!

    I am 44 years old and live in Sweden. My mind isnt a day over 15 though! And my persona isnt like most kids.
    Worked in IT for 20+ years. Im a Datacenter Design Specialist

    I love computergames. But only ONE game at the time, which I play for months, like Civ 6. Minimum hours at the time.
    When I am between games, my mood is down and I get sleep problems heh.

    Music has always been my hobby along with computers. But my music world is EBM/Industrial, which I learned to keep to myself, because "normal people" simply dont understand my music world and ALWAYS jump to the wrong conclusions.

    I am a big fan of Isaacs channel! I found him about 1 year in his releases.
    I always been interested in physics, space and and the universe works. Whats possible to do, if you had X Y Z.
    My mathskills max out at 1+1 = 3, so I always had problems "proving" that I understand when talking physics to others.

    Isaac explains everything in a unique way, that most people can understand. But I understand even when he talks math. Or how to prove what he talks about.
    Like how to move a star! I had no idea that was possible. Until Isaacs episode, then its easy to understand and explain!

    Because of Isaacs channel, I am smarter today, then 3 years ago. And I can explain physics and other stuff MUCH better!
    I am not just saying that.

    I love the alien civ episodes, because he base his imagination of aliens (There is no facts about any aliens, other then laws of physics and math is the same everywhere)
    I always loved Sci/fy, but even as a kid....how possible different aliens was and how possible the technology in movies to be "real", I could tell. But not explain what I based it on, or proving anything because I dont understand math ;)

    I never liked Star trek, pre 1990, because how silly aliens where.
    But, 1990, alot of aliens in movies started to be at least remotely possible. Even if way to many was humans, 2 arms, 2 legs 1 head, talking = The chance that 2 different alien spieces have that.....is less then your chance to guess the name of the number 100 first born human.

    I get myself in problems quite often! ;)

    The movie Aliens in 1986,
    people said, that horrormovie but silly because Xenomophs wouldnt "work".
    I got my whole school class against me for claiming that they where very possible.

    It was in Biology class, and that teacher SHOULD have known that we have xenomophs on earth. Organism that lays eggs in different animals, who they have nothing in common with. The organism "eats" the matter in the victom, to turn it into the building blocks for its own cell building. (No digistive system, they eat everything, and their DNA/cells, uses the atoms to create its own cellmatter). This group of life, have no prefered target. Anything biology, and they eat, everything.

    I always wondered why I understand operating systems, games, politics, phyics, and emotions much faster and better then others.

    I got diagnosed with ADHD 6 months ago, which explained a lot. I have 2 levels lower IQ then avarage, but my fluid Intelligence is off the sharts (I had no idea what that was)
    Short version: Fluid intelligence is how fast you "get things". The Ability to see order in chaos. To "see the matrix".
    How you can understand complexed things, like an operating system, what a black hole is, to see the whole "situation" with more info then you can process. To "see" emotions in people. To "know" how a game works by just looking at it.

    All this, without reading any manual, using math, or getting teached first....is fluid intelligence. NO THINKING! You know when you see it.

    Pleased to be here!

    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.
