Of the entire electromagnetic spectrum, we humans only percieve a very narrow range of frequencies/wavelength with our eyes.
Red, orange, yellow, green, blue indigo, and violet.
Suppose we were to assign false colors to the frequencies/wavelengths invisible to us, such as “colorizing” ultraviolet as red, and infrared as violet, and continuing this colorization extension throughout the EM spectrum…a continuously repeating rainbow: …ivroygbivroygbivroygbivro…
Obviously, no camera or film can do this alone: we would need an entire range of EM sensors and a computer to combine the images.
Suppose we wish to image a galaxy in the full spectrum…from radio waves all the way up to gamma ray and cosmic ray frequencies.
What would we “see”?
