Smh my head
- Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world 1 week ago:
Things like platinum notwithstanding, It will almost always be more expensive to go get things in space than on earth.
Hell, even on earth it is often too expensive to get metals like iron if there isn’t rail or a port nearby. Imagine having to fly iron ingots around and the associated aviation fuel cost. Whatever crazy fuel bill you’re imagining, multiply by a hundred or more if you’re imagining getting it from space.
No, all of those metals in space are best used to build some future version of our civilization _in situ. _
- Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world 1 week ago:
Very true. However, it doesn’t add new material to the equation. If we need it to build electrical infrastructure, recycling won’t suffice.
Recycling aluminum is actually literally the best thing you can recycle in terms of environmental impact and cost efficiency. There are other things we recycle, but nothing pays off nearly as well.
- Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world 1 week ago:
That alternative material is aluminum. It’s like a top four abundance material in the crust. It’s just super fucking hard to refine from minerals that don’t like to give it up without oodles of energy. Like, turn minerals into plasma levels of energy. So the irony is, to grow our energy economy past the need for copper, we will first need to grow our energy economy.
Should fusion ever actually meet its promise, then this is one of the likely things we could do with this level of energy.
If we ever become a spacefaring civilization, it’ll almost certainly be necessary during the colonization of other planets/moons/asteroids, since the geological processes that concentrate copper on the earth are not present in those places. Whereas aluminum is plentiful any place rocky.
- Comment on science never ends 1 week ago:
Understand that science is a name given to both a method, and to a mostly self-consistent body of models that can be used to make useful predictions. Science doesn’t get things wrong. Science gets iterated upon.

- Comment on I was a British tourist trying to leave America. Then I was detained, shackled and sent to an immigration detention centre 1 month ago:
That would qualify as work according to the US gov. Because by doing these chores, you are potentially causing someone to not need to pay a nanny or whatever. Be careful how you define work – you don’t need to be directly paid.

I hate fishing games. Just chance games to waste time. But I also hate fishing so…

Starfucker and other songs would be considered quite horny. But it’s always more “rage sex” than sexy sex. So I mostly agree. Except when I don’t ;)
- Comment on 90s band alignment chart 2 months ago:
Big Naked. Nine in Nails. Marylin Manson. Our Lady Peace, Alanis Morissette. There’s quite a few that could be both. But, alas, this is only a two axis graphic ;)
Also, how to tell I grew up on Canadian radio…
- Comment on 90s band alignment chart 2 months ago:
Yeah, no kidding one of the most depressing songs ever: youtu.be/T69Yk6IccL0 – The end is the Beginning is the End (Batman and Robin soundtrack)
Also one of the best tracks ever.
