Where did the universe come from? In this video, we explore the origin of our universe, from the Big Bang theory to the early moments when space, time, and matter first appeared. Scientists believe the universe began nearly 13.8 billion years ago, expanding from an incredibly hot and dense state into the vast cosmos we see today.
