Big Bang Evidence
Produced by Twig, this animated video looks at evidence for the Big Bang Theory.This includes descriptions of:
• Hubble's observation of a red shift, which is evidence for an expanding universe.
• The distribution of cosmic microwave background radiation, which was discovered in 1965 and is consistent with radiation produced by the Big Bang being spread in all directions.
• The abundance of lighter elements in the Universe, which suggests that these first elements (hydrogen and helium) were formed at the Big Bang and are the precursors for all other elements.
The video is visually attractive and the narration is both informative and accessible. It is suitable for secondary school students and would be a useful introduction for post-16 students.
