Hmm. 🤔 Did they use Rimworld as the simulator?

[–] FlyingSquid@lemmy.world 28 points 1 year ago (2 children)

Not if one of those people is Elon Musk.

[–] pleb_maximus@feddit.de 35 points 1 year ago (3 children)

Oh, but I think he should be at the top of the list of people who go first. I'm sure he and 21 of his billionaire friends will surely pull through.

[–] FlyingSquid@lemmy.world 20 points 1 year ago

I would definitely volunteer him.

This reminds me of am episode of Love Death and Robots

If they provided mechs for each person, you might see more people signing up. Don't mention the space bugs though.

Imagine the public freakout if 22 billionaires announced that they were going to Mars together.

Until Eric is caught cheating on his girlfriend with Alice....

I don't think the bare minimum of people creating a self-sustaining population can afford to be monogamous. Though it doesn't take many generations before that can start, 2nd gen might even be able to, assuming 1st gen has enough kids.

Speeds are ok but the latency is horrible.

Average is 750'000 ms ping to Earth, but it depends on season

I hope it has Marsnet and be fully decentralized.

[–] Pixel@lemmy.sdf.org 8 points 1 year ago

Guys, I signed up 22 times. Don't worry, I got this.

I remember reading somewhere it was around 500-1000 for a sustainable human colony to begin. Did we get better at avoiding Hapsburg Jaws?

[–] Genrawir@lemmy.world 12 points 1 year ago

I was wondering the same thing before reading the article. This is for a 28 year mission, and doesn't include setting up the base, or power and water supply.

[–] scarabic@lemmy.world 1 points 1 year ago

If it’s basic generic viability I’ve always heard 30-60 though I couldn’t name a source for that.

[–] afraid_of_zombies@lemmy.world 1 points 1 year ago

I think that number comes from long term genetic diversity issues. Some rule in biology about inbreeding depression came up with it

[–] BeardedSingleMalt@lemmy.world 7 points 1 year ago (1 children)

Only 22? Should that include someone for Graphic Design?

[–] itsmistermoon@feddit.cl 2 points 1 year ago

I’m sure the “computer-savvy” nephew that came along to the colony can do the designer’s work, a lot cheaper too

[–] ramble81@lemm.ee 4 points 1 year ago

And then you wonder why it specifically states "no more...no less .."

[–] omega_x3@lemmy.world 3 points 1 year ago

Does playing RimWorld count as running a simulation? Cause managing 22 people is too much trouble, unless a few might just be there in case the crops don't do well.

[–] Blackdoomax@sh.itjust.works 2 points 1 year ago (1 children)

I don't know where i got this same number, maybe in a course talking about genealogy in school, a'd i use it since then.

[–] Buddahriffic@lemmy.world 2 points 1 year ago

Iirc, the Matrix used that same number for determining how many humans to leave alive outside of the matrix so that the community wound be self-sustaining before they were able to ramp up breaking people out again.
