Are there any dark forces? If you believe in them, you will see them behind the scenes. Some people see them in the forest, some see them in the unclear. Other people see them below the ground.
How can you view the dark? There is no such thing as a camera able to capture the absense of light, or radiation for that matter. There is nothing captured. The simple solution for me is probably obvious for you too. Capturing light reveals what is hidden. That is what you see. If you want to.
