In November 1884, an astronomer claimed that he found a planet in the shape of a cube beyond the orbit of Neptune. So, while earthlings argue about whether our planet is flat or spherical, let's imagine how our lives would change if we lived on a cubic planet.
Since we live on a spherical Earth, its gravitational attraction is the same at any point. But with the advent of the cube, everything changes. You will have to first choose one of the six facets for life, but the pleasure of being will be difficult to obtain. Wherever you go, everywhere it will seem as if you are climbing a steep hill.
On a cubic planet, gravity will be maximized at the center of each face. Therefore, the farther you move away from the center, the greater the force of attraction will feel. By the way, the landscape on the edges of the planet will be stony and barren, as the water will flow to the center of each face. In addition, the edges and corners will turn into dangerous places to live, because the atmospheric layer in these locations will be thin or it will not exist at all.
The climatic situation will also change, but the situation depends on the characteristics of the planetary rotation. If the axis passes through two faces, the climate will remain the same, but it will be more extreme. The upper and lower faces will become as polar as possible, while the other four sides will retain equatorial heat. But the Earth can rotate around an axis that passes through two angles. Then each side has a temperate climate, devoid of precipitation and extreme temperatures. By the way, you have a chance to go out into space, being on the planet. How so?
The atmospheric layer is held by gravity, but in the cubic Earth this force is concentrated in the centers of the faces. It turns out that the atmosphere in these areas will be dense, and at the corners and edges it may not exist at all. That is, the sharp corners will actually be in outer space (go beyond the atmosphere). Then try on the spacesuits and go!
As you can see, the cubic Earth version will not bring catastrophic destruction to local residents. The truth will have to get used to the new climate and stay away from the edges. But objects in space tend to spherical shape, so nothing like this does not threaten us.
