I once heard that scientist thought they heard some sound in space like people are singing. I thought this was just a hoax. We were taught in school that there’s no sound in space because there’s no air. But it seems all of them are wrong, the sound exists in the form of electromagnetic vibrations that pulsate in similar wavelengths as the sound we hear.
NASA has design an advance instrument that they were able to record electromagnetic waves and transfer them into sound that a human ear can hear.
