            investigations made into the nature of light, this book would become several
            volumes long and, in any case, would not surpass the quality of a physics
            book. Instead, therefore, we'll look at some of light's miraculous aspects.


                 How Do We Perceive Light?
                 Although sight is the one sense that gives us the greatest link with the
            outside world, many people do not realize that what they see is actually se-
            verely limited. Only 10% of the light entering the eye actually reaches the re-
            ceptive cells. The remaining 90% is either reflected or absorbed by other
            parts of the eye. 34
                 The human eye is sensitive to only a specific few wavelengths of light.
            As a result, there are a number of forms we cannot see, including cosmic
            rays from space, X-rays, gamma rays, ultraviolet light, and infrared radia-
            tion from the human body. The range of light visible to the human eye falls
            between ultraviolet and infrared.
                 The word infrared means "beyond red," and refers to light with a wave-
            length longer than that of red light. Light energy is given off by every object,
            and the amount of energy depends on the object's temperature. We cannot
            see the infrared waves given off by stoves, our own bodies, the world, or
            even the stars. Were we able to see infrared rays, our vision would be deter-
            mined by how hot or cold an object is.
                 The human eye also cannot see ultraviolet or X-rays, which are of even
            shorter wavelengths. These extremely short wavelengths have high quan-
            tum energy and may be dangerous enough to kill.
                 At this very moment, you are surrounded by thousands of light beams.
            Your eyes do not see them; thus, you are unaware of them. This is actually a
            blessing in disguise, because if you could see every possible form of light,
            the world would become confusing and complex. You would hardly be able
            to see anything for all the cosmic rays coming from space, and other people
            and objects would regularly change color, based on their temperature.
                 On the other hand, if you could see X-rays, then everyone would ap-
            pear as a skeleton—hardly a pleasing sight. When God created man, He
            gave him skin and muscles to cover the internal organs, bone structure and

                                                                                 87
