Even before the appearance of life, the things group in sets spontaneously, due to the interplay between attractive and repulsive forces and the positive feedbacks that appear in certain conditions. The world is not made of a homogeneous substance, but there are various kinds of groupings at various levels, nucleons and electrons group in atoms, atoms group in molecules, molecules group in pebbles, stars group in galaxies and so on. |
