Imagine a scenario where you flip a switch to illuminate a room, yet the light never reaches you. It’s akin to the universe as we perceive it—every moment we observe is a flicker from the past, light having taken billions of years to travel. We exist amidst echoes, always interacting with history, never the present. This paradox prompts us to reconsider our understanding of time and reality. What if the now is perpetually elusive, always a step ahead of our perception? Such thoughts challenge us to expand our grasp of the cosmos and our place within it.
