Abstract
In this paper, we reexamine the fundamental nature of mass and energy, contending that these traditionally regarded physical quantities are instead observed phenomena, continually emerging, and vanishing in cyclic patterns intricately interwoven with the essence of time. We uncover that the cyclical behaviour of mass and energy leads to the quantization of energy and the wave-particle duality, defining phenomena in the quantum realm. Intriguingly, these cycles also unveil the concept of 'Dark Matter,' manifesting as mass absence during specific phases. Furthermore, we present an illuminating perspective on energy transformations, unifying gravity and electromagnetism. Our exploration not only challenges existing paradigms but also delves into the philosophical distinction between the ephemeral nature of mass and energy and the enduring act of observation, redefining our comprehension of the universe's intricate fabric.
