The universe is approximately 13.7 billion years old—but why can we observe regions as far as 46 billion light-years away? This video takes you on a journey through the physics of light and time, explaining why looking into space is also looking into the past. We explore cosmic expansion, the significance of the Cosmic Microwave Background, and the limits of what we can observe. With insights rooted in Einstein’s theory and modern cosmology, this is a deep dive into the true structure of spacetime and the visible universe.
