The 21-cm line of atomic Hydrogen is very common throughout the Universe that some scientists suggest that if we want to send messages to aliens we should use the frequency of π times this frequency (why?). What is the frequency they suggest to use? A. 4.49 GHz B. 1.43 GHz C. 2.75 GHz D. 3.62 GHz   Is the answer B? The use of frequency π times is to avoid destructive interference such that the radio message could travel through space without distortion? Thank you very much!
