Cosmological-horizon Memes

Someone's been watching too many flat-Earth documentaries while studying cosmology! The Cosmic Microwave Background isn't some cosmic ocean you can sail to—it's literally the oldest light in the universe, radiation left over from about 380,000 years after the Big Bang. It's EVERYWHERE, surrounding us in all directions like a cosmic baby photo. Trying to sail to the "edge" of the CMB is like trying to sail to the edge of time itself! Next they'll be asking if we can take selfies with the Big Bang! 🤪
