The universe is roughly 13.8 billion years old ? a number so enormous it’s hard to imagine! Scientists learned this by studying the universe’s expansion, like pressing rewind on a growing balloon to see where it started. That starting point is the Big Bang. Clues like the light from ancient stars and the cosmic microwave background (leftover radiation from the Big Bang) helped! It’s like solving a giant space puzzle, and each piece helps us understand how everything began billions of years ago!
