Discovery of cosmic microwave background radiation

Ever wondered how scientists confirm the universe's explosive birth?

Imagine you're trying to confirm if a balloon popped suddenly because you heard a loud bang.

Scientists looked for a faint glow left over from the universe's first moments. This glow is like the balloon's echo, confirming the bang.

Example

Just like the echo confirms the balloon popped, the glow confirms the universe's explosive birth.

Remember this

The cosmic microwave background radiation is the universe's echo, confirming its explosive birth.
