  • I disagree.

    Its slightly firmer science than star trek, but it still makes a lot of license IMO.

    I dont think the cost of sending humans to Mars or to do asteroid mining will ever be justified. Bots, and not humanoid ones will explore the frontier of space, and collect the minerals we need.

    If you think about all the stuff humans need to survive for any length of time it just doesn’t make any sense to send a human.





  • Ay?

    Do you mean only the super rich will be able to travel?

    The only travel anyone will be doing in the next 100 years or more will be going to the moon to squeeze into a tiny smelly hab module to figure out how to avoid getting regolith in your ass crack.

    I think space travel will be the exclusive reserve of hard core science nuts.

    Even in say 500 years. Will there be a “colony” on Mars with anything more than a dozen science nerds? I doubt it.



  • Im not really sure what you mean by lying down? You’re not always lying down. Surely gravity is less relevant when you’re lying down anyway.

    … I dont have a good understanding of physics but sci-fi novels suggest a few problems on small ships.

    The first problem is the difference in gravity between your feet and your head. In a small command capsule like Artemis 2, your head might be near the centre at 0g while your feet are at the outside at 1g or even 2g. How hard does your heart need to pump blood? Would this create some kind of blood pressure problem?

    The next problem is how it would “feel”. Is it called the Coriolis effect?

    In a small ship you might experience 1g, but it would feel like you’re being spun around in a washing machine. Your ears would tell you that you’re constantly changing direction and it would 100% fuck you up. In sci-fi the spinning thing needs to be large enough that some g-force is produced without you feeling that sense of motion, or at least for ot to be small enough that you get used to it.

    Another problem I just made up is that if there’s no gravity then 100% of the inner surface area can be terminals and readouts and equipment. If you create gravity then you need a floor to walk on which will use a heap of surface area.



  • Originally I didn’t like blocking people or communities at all but I’ve realised the lemmy experience is dramatically improved by blocking idiots.

    The thing is lemmy is a relatively small community. If some nutter posts and comments every day they can really shape your impression of the place.

    Some users have very little life experience, and depth of understanding, and are just fixated on some single issue. I’m not here to argue with that type of user.

    Yesterday I blocked a community just because the single mod didn’t understand the problems caused by editorialising titles when posting articles.








  • People do still pay with cash but ofc fewer and fewer people do as cards are so convenient.

    That said, while I haven’t really carried cash for a decade or more im getting older and grumpier as time goes by and I’ve recently wondered about going back to cash for some purchases.

    Managing your privacy is a constant trade-off with convenience, i dont think im quite ready to start carrying notes and coins again for minimal benefit.




  • Of course we face huge problems at present, but we’re also more capable at implementing solutions than we have ever been.

    “we are fucked” is a bleak generalisation that can’t be rebutted. Regardless, my point remains that people have believed that throughout the ages, and have always pointed to current threats as being more existential than those faced in the past.

    There’s actually a lot of research into the issue of pessimism about the future. Honestly, it’s really interesting and I would challenge you to take a look - you might actually feel a little better about the state of the world. It’s a well researched topic but this is a good start.

    That’s not to diminish the threats we face. Of course we need to take action and avoid complacency, and of course there will be a significant and deleterious impact from climate change, probably even “catastrophic” by some metrics and in some areas. However, I’m confident that as a race we will adapt, survive, and overcome.
