Are Light and Darkness the two sides of the coin?
Ibn al-Haytham's work sheds light on the fundamental principles behind our ability to see objects. From his studies, two key observations emerge: first, without light, visibility is null, and second, without objects to interact with, light itself remains invisible to us. This becomes evident in scenarios such as traveling through intergalactic space, where the absence of matter results in nothing but darkness, despite the potential presence of photons traversing the void (assuming photons are present, they must originate from a source, and seeing them would involve their direct interaction with our eyes, revealing the source from which they were reflected or emitted).
