It’s also the only continent without a southern coast.

[–] veroxii@aussie.zone 36 points 7 months ago (1 children)

For now. It used to a few million years ago and will again in another few million.

Are you referring to the magnetic pole switch? That happens every 200-1M years, according to patterns on the seafloor. It’s been estimated that the last reversal was 780,000 years ago, so it theoretically could be any day now.

With that being said, I doubt that humanity will agree to turn all maps 180° to correspond.

I thought they were referring to the fact that under the ice its an archipelago, so if the ice melts it will have southern coasts again

[–] disguy_ovahea@lemmy.world 12 points 7 months ago* (last edited 7 months ago)

Valid point. It’s a shame humanity wouldn’t be around to confirm. lol

the continental plate also migrates

I was referring to continental drift. Places move a lot in under 200 million years. Eg https://youtu.be/uLahVJNnoZ4

So my post was a bit sarcastic that eventually it will have a coast but not on any time frame to matter to the human species. :)

Laschamp event! I just edited a related wiki page on late Pleistocene extinctions. Spoiler alert: it didn't kill the megafauna.

Yeah, because you'll fall off the bottom into space

[–] Dasnap@lemmy.world 29 points 7 months ago

Long Earth theory.

[–] h3mlocke@lemm.ee 29 points 7 months ago (2 children)

How am I supposed to know how big that is? I don't see a banana anywhere....

[–] supercriticalcheese@lemmy.world 3 points 7 months ago

it's too cold steel wool they don't have bananas

[–] KillingTimeItself@lemmy.dbzer0.com 2 points 7 months ago (1 children)

because it's smaller than a pixel :)

[–] ignotum@lemmy.world 4 points 7 months ago* (last edited 7 months ago) (1 children)

I yeah i see it now, it's the pixel in the bottom right corner

it's 3% more banana-colored than the surrounding pixels, you can't miss it

Uh, antartica is about as wide as the U.S. and about as tall as it is wide.

So, I just feel like I’m being bamboozled here

[–] disguy_ovahea@lemmy.world 20 points 7 months ago* (last edited 7 months ago) (3 children)

Mercator maps are lies.

That is inaccurate. The correct way to use the tool is to lay the continent over the US. It skews the size and scale appropriately in order to provide an accurate measurement.

Antarctica vs US

It’s also larger in area than the US, including Alaska and all territories.

The total area of the US and its territories is just over 3.8 million square miles. Antarctica's area of 5.4 million square miles makes it 1.5x the size of the US.

The correct way to use the tool is to lay the continent over the US.

Typical American, declaring that the US is the default country to compare every other country to!

On a more serious note, putting things side by side is the same as putting them over each other. Difference in height are not the same though, as closer to the equator size shrinks. The best way to compare is take two things and put them side by side on the equator - that's where there's least distortion.

Just look at the map, what more proof do you need?

[–] cobra89@beehaw.org 3 points 7 months ago

Yeah it's definitely not a real projection. If Antarctica looked like that (taken top down) then the rest of the continents would not be oriented like that.

[–] KillingTimeItself@lemmy.dbzer0.com 15 points 7 months ago

and we certainly wont be in a few hundred years lmao.

[–] workerONE@lemmy.world 13 points 7 months ago

Big if true

[–] Diplomjodler3@lemmy.world 11 points 7 months ago (2 children)

Wait what? Did we just find Hitler's secret Antarctica base?

[–] disguy_ovahea@lemmy.world 13 points 7 months ago (1 children)
[–] Diplomjodler3@lemmy.world 16 points 7 months ago

Nonsense! Did you see how big that thing is? Definitely Hitler!

According to this projection, it's bigger than Africa

[–] Daft_ish@lemmy.world 11 points 7 months ago (1 children)

Can we talk about how big that structure is?

[–] Obi@sopuli.xyz 9 points 7 months ago

About three times the size of Europe it seems, one hell of a building.

[–] Landsharkgun@midwest.social 9 points 7 months ago

Ok, but that's unironically a great map for a TTRPG campaign.

I'm thinking Lovecraft. Plateau of Leng and all that. There's just this huge, impassable land that goes south for what seems like forever. And...things...occasionally wander out of it.

[–] A_Chilean_Cyborg@feddit.cl 4 points 7 months ago (1 children)

My country holds a claim and permanent population to a portion of antartica.

[–] AnUnusualRelic@lemmy.world 12 points 7 months ago (3 children)

Many have "claims". None are valid though.

[–] Kolanaki@yiffit.net 4 points 7 months ago (2 children)

How many flags are planted? No flag, no Antarctica. Those are the rules that I just made up.

[–] explodicle@sh.itjust.works 2 points 7 months ago (3 children)

So then like a bunch of people own Mt Everest.

Yeah but the permanent population is there, sakd claim precedes the treaty.
