Our Universe is not silent.. Yes, space is a vacuum – so it generally doesn’t carry sound waves like air does here on Earth. However, sounds do exist in outer space, we just can’t hear them. Various probes that zoom through the space are capable of capturing radio emissions from astronomical objects. NASA’s scientists have designed special instrument known as ‘astronomical interferometer’.. ..which can record these electromagnetic vibrations, and transfer them into sounds within range of human hearing (20-20,000 Hz).
