The pebbled path to planets

Every big planet begins with a pebble. Okay, not just one. It starts with lots of pebbles — a flat sea of them stretching perhaps hundreds of times wider than the distance from Earth to the sun. Their sizes vary greatly. Some may be mere dust particles. Others may be small to fairly substantial rocks.
