Human senses are fairly sophisticated. As we discussed in a previous article, our vision is pretty good compared to some animals, but inferior to others. What we see is only a tiny sliver of the electromagnetic spectrum, but we still managed to discover the rest of the spectrum using science and technology. What evolved into our visual spectrum, our rainbow, does make sense. What we call visible light is a lot of the wavelength radiation that the sun produces. But it certainly isn't the entire picture, especially when you consider technology and other sources of radiation that aren't the sun.
So let's imagine some way that a human could see everything. Perhaps it's a gene therapy that replaces the blue, green, and red photosensitive proteins in the retina with 10, 20, or 30 new proteins that are sensitive to the full range of the electromagnetic spectrum. Or, to continue on the theme of the previous article, perhaps a multispectral camera that is hooked up to a virtual reality headset.
However it's done, that person can now see every form of EM radiation as interpreted by how humans normally interpret color. For the sake of simplicity, this system doesn't account for polarization like some forms of animal vision do. This stretching of color perception is also on a logarithmic scale. So what would the world look like? ...[Continue reading on Factorialist]
