  • 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.






  • 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.


  • For years it has been repeated again and again that gas is needed to firm renewables when “the sun doesn’t shine and the wind doesn’t blow”. Events have shown the opposite: renewables are needed to firm oil, gas and coal when the ship won’t go and the pipeline doesn’t flow.

    Indeed.

    Nothing new here though. Half of us have known we need to decarbonise industries as quickly as possible, while the conservatives have as usual been trying to avoid doing so.

    As I’ve said a bunch of times over the last few weeks, I’d like Albo and other leaders of like minded middle powers to stand together and condemn Trump’s behavior. It’s absurd that everyone is too scared to say anything. He’s caused global harm in order to further his own interests.



  • Tough one.

    Sentences in modern societies should focus on mitigating the impact to victims and rehabilitating the offender.

    Crimes that harm minors intentionally are a special category, and while I understand the hatred I think that wanting to punish the perpetrator for no other reason than revenge doesn’t really help anyone.

    The requirement that permanent residents have their visa’s cancelled when found guilty of a crime is really just to ensure that the migrants we accommodate are fit and proper, compatible with Australian values. In this case, we’ve accommodated this guy for the last 40 or 50 years, and to remove him for the last 2 or 3 years of his life when he’s vulnerable is just vengeful punishment because the law happens to allow it in this case.

    I mean, there’s plenty of Australian citizens convicted of similar crimes who are allowed to serve their time and then released to live out their days in Australia.

    I don’t think that returning him to the UK serves any purpose.
