Cosmology and Astrophysics

We'll take a brief look at the developments made by 19th and 20th century astronomers and cosmologists. We'll be using some docos, chalk and talk, and maybe a few classroom exercises we'll take a brief look at the history of space and time. 

Crucially we'll try and keep this at level 5 in the curriculum and tell more of the story, but also explain how 'we' - humanity knows what we know.

Having said that if you're game for some pythag - we can derive time dilation near the speed of light too.
