By the end of the lesson you will be able to recognise and describe the time line of the early universe that led to the formation of matter.
Engage
The universe is measured using many different methods
The age of the universe is found using our understanding of redshift and the expansion of the universe

2. Why can't we see the whole universe?
3. Why do we know is the size of the universe so much bigger than the can see?
