Our Universe and the Big Bang

Description

The size of the universe, its expansion and the Big Bang are the topics for discussion, in this KS3/4 physics video.

Astronomer Pete Edwards attempts to explain just how big the universe is, and reveals how astronomers measure the distance to the stars, using concept such as parallax and redshift.

Pete and cosmologist Carlos Frenk describe how scientists think the universe started with a Big Bang and grew from almost nothing into the web of stars and galaxies that can be seen today.

Pete and Carlos also reveal how they are creating their own universe inside a supercomputer at Durham University.
