Okay kiddo, imagine you're watching your favorite TV show. You know how the show starts with the opening credits and then the story begins? Well, the big bang observer is kind of like that - it can help us watch the beginning of the universe!
A long, long time ago, before you and I were born, the universe began. It started as a tiny, tiny dot that was extremely hot and dense. Suddenly, it began to expand, and it's still expanding today!
Now, we can't go back in time and watch the universe begin because it happened so long ago. But scientists can use something called the big bang observer to help them see what happened.
Think of the universe like a puzzle. When you put a puzzle together, you can see a picture forming. Similarly, scientists use the big bang observer to put together all the little pieces of information they have about the universe's beginning.
The big bang observer is like a big telescope that helps scientists see the universe better. They use it to look at things like the cosmic microwave background radiation - which is kind of like a "glow" left over from the big bang. By studying this "glow," they can learn more about how the universe began and how it has changed over time.
Overall, the big bang observer is like a really good detective that helps us understand the mysteries of the universe's beginning. It's an important tool for scientists who want to learn more about where we came from and how everything started!
