Why is the world round?
There is a law in physics that ensures that the world we live in is round. If you are now asking "why", you should think of the gravitational forces that act here everywhere on us and on the mass particles of the world.
In the beginning there was the big bang
- As a result of the assumed Big Bang, innumerable, very small particles of matter whirled through the whole universe and began to come together.
- The closer these particles came, the more gravitation they exerted on each other. This is a physical phenomenon, the particles attracted each other.
- This is how the sun came into being and around it the other planets in our solar system.
That is why the world is almost round
When asked "why" you have to consider the physical component.
- In the physics is the gravitation resp. Gravity is one of the four basic forces. It causes crowds to attract.
- This is why leaves fall to the ground and any ball thrown so high will eventually fall back to the ground.
- It ensures that the planets move on their orbits around the sun.
- The mass particles of our world also attract each other and try to find the optimal shape. This is only once the round, spherical shape, because then all parts of the surface are approximately the same distance from the center of the world.

The world is an ellipsoid of revolution
Strictly speaking, the world is not round, but rather has the shape of a potato.
- This is because it rotates around the sun in an elliptical orbit, but at the same time also rotates around itself.
- These rotational forces on the elliptical orbit work slightly against gravity, which is why the world is brought out of the ideal round shape.
- The world is slightly flattened by the interaction of these forces at the poles, but at the poles it becomes rather bulbous, which is why it is only almost round.
