we see nothing in the dark but How we see the darkness
There is no such thing as darkness. What a surprise! Let's see what physics says about this! We can see an object only when the particle of light falling on that object returns and catches our eye again. The light that catches our eye is actually the smallest part of the massive electromagnetic radiation in the universe. There are several types of light in this electromagnetic radiation. But we do not see everything. Because our vision is limited to the smallest part of that radiation. Suppose we see a bird as colorful as a cat, but it does not. Because cats don't have those cells to see color. Again, they have cells that we don't have, so they can see at night, but we can't. When we talk about seeing something, it is basically visual perception. Suppose a light emanates from a source and falls on a bird. It bounces again and is reflected through our eyes through the camera, that reflection again transfers the cells of our eyes to the neuron cells ins...
