👉 Before the light particles, the universe was shrouded in darkness, a vast expanse devoid of any illumination. However, as the cosmos began to expand and cool following the Big Bang, fundamental particles started to form. Among these were light particles, also known as photons, which are the basic units of electromagnetic radiation. These particles, though incredibly small and fast-moving, played a crucial role in the early universe's evolution. They interacted with matter and energy, influencing the formation of atoms and, ultimately, the structures we see today, such as stars and galaxies. The presence of light particles marked a pivotal transition from the dark, chaotic infancy of the universe to a more structured and observable cosmos.
