Fantastic mindwander premise of the day

Hey sci-fi aspirants and cube-bound mindwanderers, this morning I read the funnest starter setting with just enough scientific substance.


What would Earth be like to us if it were a cube instead of spherical?

As the responding physicist describes it, something extraordinary would be required of the planet’s skeleton to preserve the cube shape, but granting that, the gravity of cube-Earth would cause the water and atmosphere to collect in the center of each side, leaving the edges barren and exposed to space and giving the sensation that the sides are cupped (nothing like the image above). Cooler still, isolated side environments would not exchange weather, and probably not cross-pollenate or cross-breed, so truly independent environments - even different atmospheres could develop on each side.

It’s already sounding ridiculous as I try to summarize. Better to read the item yourself because when the explanation starts with the scientific principle, the outrageous extrapolation seems somehow plausible.
