cubical Earth

[Pasta]

@Chronos

And in one of the previous threads, someone did actually construct an equivalent of Blakeyrat’s diagram from a numerical simulation. Digging it up, the links are dead now, but Pasta (who made them) is I think still around; maybe he could re-post them?

Yeah, I intentionally broke any non-anonymous URLs when the board went searchable. (Actually, perhaps mods can deal with this by editing links in old posts?)

In any case, here are the three posts from this thread that had links in them, now with new links. More details in the thread itself.

I’ve got a handy little Earth[sup]3[/sup] model going. I’m using actual Earth numbers for the masses and volumes of the planet, atmosphere, and oceans. Here are some first data showing surface gravity and the extent of the oceans. The oceans are 125 km deep in the middle!

Here’s a slice through the center of the cube showing the gravitational potential energy and its gradient (which shows the direction of the pull of gravity.) I show the interior for anyone interested in making a tunnel.

Apologies for the triple post. An equal-scale slice with more detail
