If there is life on another planet within our galaxy, why would we expect to learn that this life would probably use the same narrow range of wavelengths of the electromagnetic spectrum as we do for a source of energy and information?

Question

Quizplus · Accepted Answer

The use of a narrow range of wavelengths of the electromagnetic spectrum for energy and information by living organisms is based on fundamental aspects of photon energy and light absorption. It is not solely dependent on the wavelength that hits the Earth or the availability of other wavelengths in nature. Therefore, it is reasonable to expect that different forms of life on other planets could use a different range of wavelengths for their energy and information needs.
