Definition: A theoretical framework proposing that light propagates through space-time in dimensions exceeding the conventional three spatial dimensions. In the context of Xenux theory, light is postulated to traverse additional dimensions beyond the familiar dimensions of length, width, and height. This concept challenges traditional understandings of light propagation and suggests a more intricate nature of its movement through the fabric of the universe.

Origin: The term "Xenux" is derived from a combination of "zenith," representing the highest point or apex, and "flux," denoting continuous change or flow. It symbolizes the elevated perspective and dynamic nature of this theory regarding the behavior of light.

Usage: Xenux theory represents a paradigm shift in our comprehension of light, suggesting a multidimensional trajectory that extends beyond conventional spatial boundaries. While still largely speculative, it opens new avenues for exploration in the realms of theoretical physics and cosmology, inviting further investigation and debate among scholars and researchers.
