A radio telescope.
As defined by research on the topic of the Electromagnetic Spectrum, no human can hear radio waves. No human can hear any part of the Electromagnetic Spectrum except gamma rays, which have enough energy to light up. If humans were to hear radio waves, they wouldn't need radios (except from the original form).
Radio waves are often referred to as space waves because they have the ability to move through space. Radio waves are a type of electromagnetic radiation.
