How would life on Earth if it had the shape of a CUBA?

This is exactly the question one of the subscribers asked me recently. To answer it, you first need to figure out why everything in the Universe is spherical or close to it.

The answer to this question lies in the very process of the formation of the planet. After the formation of the Sun, a lot of debris, dust, gas, ice and other building materials for the formation of planets remained around it. Over time, due to gravity, all this matter began to accumulate and stick together. The clumps became larger and larger, turning into planets. When the clumps collided, a huge amount of energy was released, and as a result, the newly formed planets turned out to be hot and melted.

The force of gravity tried to pull each atom as close to the center of the planet as possible, and the only way to bring all the atoms as close as possible to the center of gravity of the planet at once is to form a ball, which actually happens to the planets.

However, this process will not work with much smaller bodies such as asteroids. In this case, the gravitational field of the asteroid is too weak to overcome its mechanical strength. Therefore, small bodies are not spherical, but retain such an irregular shape.

Of course, for the reasons described above, the planet cannot take the shape of a cube, but let’s just theoretically assume that the Earth has taken the shape of a regular cube. In this case, the surface of the Earth will be divided into six faces and it will not be so easy to travel around the world on such a planet.

On a cubic Earth, the force of gravity will be greatest in the center of each of its faces, and only in the centers of the faces will it be directed vertically downward. Therefore, the further a person moves away from the center of the face, the less gravity will act on him, but it will no longer be directed strictly under his feet, but a little to the side, which will make it seem that he is climbing a high mountain and the further from the center of the face, the steeper the «rise» will seem.

The terrain itself along the edge would be rocky and dry as all the water would collect in the center of each edge. Also, the atmosphere along the edges and corners of the Earth would be too thin and uninhabitable. On each facet of the Earth in the center there would be a large ocean, around which there would be a thin area suitable for life, further from the center of the face there would be mountains with a rarefied atmosphere. The climate of such an Earth would depend on how it rotates around its axis and how the cube is oriented relative to the Sun.
