Hello, Well this question proves to be quite interesting from a scientific perspective. It is important to note that there is no region completely devoid of electromagnetic radiation. Even in the darkest shadows, there is always a faint presence of electromagnetic energy, albeit significantly less than in the surrounding areas.

When an opaque object blocks light from a source, it creates a shadowed area. However, this is not an absolute absence of light. Some photons still manage to scatter and diffuse into the shadowed region, providing a dim illumination. This is due to the wave-particle duality of light - it behaves both as a wave that can diffract and bend around objects, and as particles (photons) that transfer quantized energy.

Furthermore, even the darkest regions of the universe are permeated by the cosmic microwave background (CMB), a remnant of electromagnetic radiation from the Big Bang. This means that shadows on Earth, and indeed any part of the cosmos, are suffused with this faint but ubiquitous energy.

From a philosophical viewpoint, one could argue that shadows are not a true absence of energy, but rather a relative lack of it compared to lit areas. They result from the intricate relation between electromagnetic radiation and matter - a subtle yet essential interplay of energy.
