Okay kiddo, let me explain what chirp mass is. Imagine you have two birds that are chirping at different pitches. Now, what if they started chirping together and the pitch of their chirps gets higher and higher? This is what we call a chirp signal.
In space, we can observe chirp signals from two massive objects (like black holes) that are orbiting each other. As they get closer to each other, they emit gravitational waves that we can detect on Earth.
Chirp mass is a special number that helps us understand how these objects are orbiting each other. It's like the weight of the two birds chirping together. The chirp mass tells us how heavy the objects are and how close they are to each other.
Scientists use chirp mass to study these massive objects and learn more about black holes and the universe. Pretty cool, huh?
