Interestingly, as dominant as our visual senses are, they are really not that great. Think about all the things we cannot see. For example, our eyes can perceive but a very small spectrum of vibration in the Universe. The vast majority of vibrations are outside our spectrum and are not visible to us. This does not mean they do not exist. For instance, vibrations in the ultraviolet spectrum and infrared spectrum can be seen by special cameras (and some other creatures) but are totally invisible to us. We have also designed instruments to perceive other vibrations such as gamma rays, x-rays, and radio waves. All around us, these invisible vibrations are ever present but we are unaware of them because we cannot see them. Imagine for a moment what it would look like to be able to see x-rays and gamma rays. Things would look a lot different to us.
