These scientists, a radio astronomer who discovered the Big Bang's echo, wanted to learn more about the early universe. They used a special telescope to listen to the echoes of the Big Bang, which is like hearing a very old and faraway sound. By studying these echoes, the scientists were able to learn more about how our universe began and how it has changed over time. It was like listening to a cosmic history lesson!
