It is a striking cosmic consistency. In a universe filled with chaotic collisions, jagged asteroids, and erratic space debris, why do the largest objects always smooth themselves out into near-perfect balls? The answer is not a cosmic coincidence; it is a profound manifestation of fundamental physics shaping our reality.

Every object in the cosmos that possesses mass exerts a gravitational pull. This force acts like an invisible, all-directional magnet, drawing everything toward the exact center of the object's mass. In the early stages of a planet's life, it does not look like a sphere. It begins within a protoplanet...
