The Big Bang Theory states that the universe began about 13.8 billion years ago from a hot, dense point. It started expanding rapidly in a process called inflation. As the universe grew, it cooled down, allowing particles to form. Over time, these particles combined to create stars, galaxies, and other cosmic structures. This theory helps explain the current distribution of matter and the cosmic background radiation we observe today.
In three to five sentences, briefly describe how the big bang theory explains the origin and evolution of the universe.
