Gravity and the Birth of our Solar System
The nebular theory explains how our Solar System formed from a giant cloud of dust and gas approximately 4.5 billion years ago. Gravity played a crucial role in this process, pulling particles together to form larger clumps. The densest part of the cloud ignited nuclear fusion, creating the Sun, while the remaining material coalesced into planets, moons, asteroids, and comets. The gravitational force between the Sun and these objects dictates their orbits. This cosmic tale underscores gravity's importance and ties into the Big Bang theory, which describes the universe's expansion from a massive explosion. The story of our Solar System highlights the wonders of the universe and invites continuous exploration and discovery.
