The biggest expense was installing the mantle ducts to keep the carbonate-silicate cycle operating.

Who's going inside to hold the bolt? Should have used a T-nut.

[–] SkyezOpen@lemmy.world 6 points 1 year ago

Just ask the mole people.

Someone make use of AI and show us some coastal scenery.

Maybe with a nuclear rocket drill to fasten it.

[–] AceBonobo@lemmy.world 15 points 1 year ago (2 children)

There's no way that's going to hold, right?

If that picture is to scale, those bolts are ~5km thick. Put enough of them and it should hold.

That said, the crust probably starts crumbling somewhere else creating new mountains or islands

After a certain point, the material around the bolt is more brittle than the bolt itself.

[–] hemko@lemmy.dbzer0.com 16 points 1 year ago (3 children)

Often is, but you can alleviate this with large washers like in the picture, and also by adding more bolts closer to eachothers

Would you say tectonic plates are more like wood or metal? There are different standards for both.

[–] hemko@lemmy.dbzer0.com 11 points 1 year ago

I'd think they're more like cookies, but idk I'm not really a geologist 😅

[–] usualsuspect191@lemmy.ca 4 points 1 year ago (1 children)

I think double-sided tape would be better. Or maybe we sew the plates together?

[–] hemko@lemmy.dbzer0.com 2 points 1 year ago (1 children)

Drill holes and zip tie the tectonic plates together

[–] usualsuspect191@lemmy.ca 4 points 1 year ago

Tectonic drift stitches. We'd have so much street cred in the galactic neighbourhood

Too many bolts too close and you’ve just got a perforation.

[–] modeler@lemmy.world 5 points 1 year ago

the crust ... starts crumbling somewhere else creating new mountains or islands

Exactly. The oceanic crust will (in geologic time) crack in front of the bolts and be dragged down parallel to the bit that was bolted, stacking the oceanic crust with the newer bit under the older one.

The cracking and stacking happens naturally and this creates stacks of many oceanic crust sections moving to the left of the picture.

At geological timescales everything is a liquid

[–] delgato@lemmy.world 7 points 1 year ago

I took an atmospheric science class in college and the professor described the field as “fast geology”, I like your description though that geology is the study of slow fluids!

Something like a Tapcon would seem more suitable for the job

[–] MNByChoice@midwest.social 7 points 1 year ago

Problem. Plates are still moving apart. Earth is increasing in volume, but no mass.

Floats away

Someone else remembers that episode of the Ghostbusters cartoon.

Does anti-subduction = abduction?

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

No domduction
