=====================
Professor Brian Cox witnesses the oldest light in the Universe by listening to its stretched wavelengths through a radio. This first light from the Big Bang has been stretched and transformed into radio waves and microwaves and is known as the Cosmic Microwave Background, or CMB.

This clip is from the BBC series Wonders of the Universe; a compilation of short films in which Professor Brian Cox witnesses the wonders of the universe through some of the most breath-taking environments on Earth. In the process, he reveals how the most fundamental scientific principles and laws explain not only the story of the universe, but the story of us all.

=====================
Teaching Physics?

Students could watch this clip as part of a learning sequence on the origins of the Universe. They could research in more detail the way that the discovery of cosmic microwave background radiation dramatically shifted interest away from the Steady State theory, and it remains one of the most compelling pieces of evidence in support of the Big Bang theory. Students could use a manually tuned radio or television to detect some of the CMB radiation.

These clips will be relevant for teaching Physics at KS4 and GCSE in England, Wales and Northern Ireland and National 4/5 or Higher in Scotland. The topics discussed will support OCR, Edexcel, AQA, WJEC GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 and Higher in Scotland.
