My favorite TWSBs involve hypothetical situations. Today, the hypothetical situation in question is as follows: what would earth be like if it were a cube instead of spherical?

Answer is here!

Quick summary of coolest points:
– oceans and atmosphere would “puddle” into the centers of the six sides of the cube.

– life would be isolated to the perimeters of these ocean puddles, and it is very likely that each of the six regions would be completely isolated and each region would pretty much be its own biosphere.

– huge seasonal temperature fluctuations due to—again—the isolation of the atmospheres.

– sunrise and sunset would be sudden, not the gradual niceness we see on regular earth.

How cool, eh?
