Q: What would Earth be like to us if it were a cube instead of spherical? Is this even possible?
Here on Earth (sphere-Earth), if you’re around 5km above sea level most of the air is below you. The vast majority of the Earth would take the form of vast, barren expanses of rock, directly exposed to space. If I had to guess; it’s unlikely that complex life would evolve on a cube Earth. By the by, the cube earth photo is by “Altered Realities“. It’s clearly presented, and well worth a look: Possibly Wrong: If the Earth Were a Cube.
