How do does radio signal keep on travelling in space? Shouldn’t it just fade away.
In: Engineering
radio signals are just light that we can’t see with our eyes. So if you can see a star from wherever you are, you could (theoretically) detect a radio signal. The issue becomes distinguishing the radio signal from the many other sources of noise, just like it might be harder and harder to detect a faint light if the ambient light increases.
