Okay kiddo, have you ever played the game of "connect the dots"? You know, where you start with a bunch of dots and then you draw lines to connect them and make a picture?
Well, the Blumberg theorem is kind of like that! It's a math idea that helps people connect different kinds of shapes together.
Imagine you have two shapes, like a square and a circle. Normally, you can't just stick them together and make a new shape. But the Blumberg theorem says that if you add an extra shape inbetween them, like a rectangle, then you can connect the square and the circle together to make a new shape!
It's kind of like having a puzzle piece that fits inbetween the other two pieces. And this idea is really helpful for mathematicians who want to study different shapes and how they fit together.
So, in summary, the Blumberg theorem is like a puzzle piece that helps you connect different shapes together to make new shapes, kind of like playing "connect the dots" with math.
