Physicist Brian Cox Explores How Light Created the Universe
In this documentary, Brian Cox explores how light acts as a cosmic messenger, allowing us to stare back across deep time. From the ancient pharaohs alignment at the Karnak Temple in Egypt to the sound barrier-breaking Hawker Hunter jet, we unlock the secrets of the speed of light. Discover how the Danish astronomer Ole Rømer first measured its finite speed using Jupiter's moon, Io, and how this cosmic speed limit turns telescopes into time machines.
