Earth is round, Period. For a long time, I believed, subconsciously, that earth is flat, and it was only until I got to learn that the earth is round, that it is gravity that holds everything in place. In fact, all planets are spherical to a certain degree. On any planet, the gravitational pull is equal from any given side and that attracts everything towards the center. Thus, gravity plays a key role in the existence of any planet, but what happens when these planets become a cube, or what if the earth were a cube?
What if Earth Was a Cube in Shape?
We know that it is earth’s gravitational force that allows us to move freely from one place to another, and allows transportation and civilization. But what happens if this gravitational force gets disrupted? Because all the planets including earth are round, that means that the gravitational pull is equal from all sides. Imagine if the earth were to be a cube, then the gravitational force would not be equal from all sides. While the gravitational pull would become strongest in the center of each face, the gravity becomes less towards the edges. If this happens, then all the water including oceans, sea, lakes, waterfalls, and pools would be pulled towards the center mixing salt water with fresh water. On each side of the cube-shaped earth, the water will get collected at the center.
Because the earth is round, the atmosphere blanket covers each corner equally, but when this earth becomes a cube then the atmosphere blanket with also tear, and a small bubble will be created covering only the area of the earth that has a maximum gravitational pull. This directly means that each side of the earth will get a separate atmosphere covering the only center of the face. There will be no atmosphere at the edges and thus they will become barren, rocky, and dry since all the water pools as well as the atmosphere will be at the center of each face. The atmospheric quality along the edges and corners would be non-existent, or too thin to support life.
Even if out of curiosity, you pack your spacesuit and decide to take a look at the edges then as you walk away from the center you will feel as if you are climbing a mountain as the gravitational pull at the center will keep pulling you. Walking towards the edges means that you will be walking against gravity so it will feel the same as walking on a terrain. One could possibly argue that we could explore edges through a spacecraft- fair enough? No, it is because gravity allows airplanes and space crafts to revolve inside the earth’s atmosphere or orbit, but when this orbit will surround a cube, it means that gravity will be working highest at certain points while at others there will be barely any gravity. This disruption in the force will hamper the spacecraft and it will thus explode.
What’s more, when all the water bodies will round up inside the center that means it will allow only a small piece of land for humans and animals to live. The ocean at the center will cover almost 4000 kilometers, and this ocean will be present on each face of the cubic earth the length of the atmospheric bubble will only be 100 km, and this bubble will be covering only 10 km along the ocean sides leaving probably only 1,56,315 km for humanity to thrive. And this area will also include a habitat for animals as well. Thus imagine, the earth’s population today is 730 crores, how many people would be able to live inside this limited space? Even if, hypothetically, we manage, where would we create forests? If there will be no forests, then there will no oxygen and hence there would be no life.
If you try to walk outside the atmospheric bubble, you will need a spacesuit and even if you have one there will be no atmosphere to support any kind of life also the climate would extremely cold. Thus, it is impossible to live outside the given atmospheric bubble.
The cube shape earth is only a fictional experiment. Currently, there are no cubical planets ever discovered and even according to the laws of physics, life on a cubical planet is impossible. But it would be entirely inequitable to shun the idea of a possible cubical planet. The universe is ever-expanding thus the idea where our physics gets wrong is also not so feasible. Even though none of the current physical laws could account for the idea of a cubical planet, it’s impossible to say that we’ll never discover one. Because it is where our physics end, our universe expands.
