  • or the earth being 10,000 years old?

    Humanity, or at least written scripture, is roughly 10,000 years old. So if you take humanity = earth, then yes it’s approximately true. But also, it’s an incredibly egoistic viewpoint because earth is not just humanity.

    Edit: by humanity, I mean human culture and not so much human biology.


  • fair argument

    I want to add something to it:

    First of all, a lot of that uranium seems to have been there and slowly decaying for a long time. I think, what we humans did was to “wake it up” and turn it into some more violently-reacting other elements, for the sake that we get the energy out of it at an acceptable pace. Now, though, it’s severely more dangerous than it was before.

    Also, I’ve an idea about what to do with the waste: Since the waste tends to activate itself due to neutron activation, put a lot of it (but just barely not enough to make a bomb) together and it will activate itself to react violently at very high speeds, but just barely not fast enough to explode (make a bomb). That way, you can get a lot of heat out of it rather quickly, and are left with burned-out material (which contains less radioactive potential).




  • We’ve had this discussion here on lemmy a few days ago: practically all electricity generation is by making turbines spin.

    Hydropower means river makes turbine spin. Wind power means wind makes turbine spin. Coal/gas power means combustion makes turbine spin. Nuclear means hot steam makes turbine spin.

    However, that doesn’t mean that all electricity sources are spinny things.

    • solar cells have no mechanically moving parts
    • batteries utilize chemical energy directly

    Unchain yourself from the criticisms of figures your country has implanted in you over your lifetime, and think in terms of ideas.

    Realistically, that’s not gonna happen for most people. Hear me out:

    In 1500s when the printing press was invented, Martin Luther (not to be confused with Martin Luther King) saw the opportunity to print “bibles for everyone” to transform everybody into a priest - an enlightened being that always (or at least mostly) does the good/right thing.

    We know from history that that didn’t succeed. Not everybody turned into a priest, not even close. Instead, he caused Evangelism, and is partially causal for the Thirty Years’ War.

    Realistically, people thinking in terms of ideas is an inclination you’re born with (or so I believe). There’s just a lot of people who are not gonna do that. Especially if people see themselves at a (economic) disadvantage because of it. Most people just wanna live through ordinary life.


    BTW, I guess something similar happened with the internet. When the internet was first invented, people guessed that it would lead to the total education of all human beings. Instead, it has caused smartphones, “social” media (which is more antisocial media tbh), and a lot of spreading dumb narratives. So i’m not sure it really “enlightened” the people.
