    Why Are Planets and Moons Round? Gravity and Spherical Shapes

    Meilleure citation de Why Are Planets and Moons Round? Gravity and Spherical Shapes

    “

    Roundness is the gold standard for defining what truly makes a 'world' versus just a 'rock.' It is the physical manifestation of gravity’s desire for symmetry, transforming a chaotic collection of debris into a unified, organized world.
