@astralfrontiers: 🌌✨ The Oldest Light in the Universe 🌟 When we look up at the night sky, we’re seeing more than stars—we’re seeing history. The oldest light in the universe, known as the Cosmic Microwave Background (CMB), is a relic from the Big Bang, over 13.8 billion years old. This faint glow is the afterglow of the universe’s birth, when the first photons escaped the hot, dense plasma of the early cosmos. 🕳️ It’s everywhere, surrounding us, a snapshot of the moment when the universe cooled enough for light to travel freely. Studying the CMB helps us unlock secrets about the origins of the universe, its age, and even its fate. It’s the ultimate time capsule of creation. What does it feel like to know we’re bathed in the light of the beginning? ✨ #AstralFrontiers #OldestLight #CosmicMicrowaveBackground #BigBang #SpaceExploration #AstronomyLovers #OriginsOfTheUniverse
