My knowledge of radio waves is very limited! I was reading an article that says our radio waves have reached to over 50 light years in space. I began wondering how far can radio waves travel in vacuum. There has to be a point at which the strength of the radio waves becomes so small that the signal itself cannot be detected (I wonder if it dies out completely). Does anyone know the answer?

Being an EM radiation it behaves like any other electro magnetic wave.
Cosmic Microwave Background Radiation can be seen even now, though it dates back to the Big Bang.
