3.  1. 5 mins Telescopes in space are above the atmosphere
/ no clouds / no light pollution
As distance increases so does the speed  C
C is furthest away
/ has the largest red shift
/ moving away the fastest

Stars and galaxies emit different types of electromagnetic waves
Wavelength of light increases
/ light gets redder
Biggest red shift ever from the this star means
- the star is the furthest away ever seen
- fastest speed of recession ever seen
All matter started from a single point
( singularity)
A massive explosion sends matter outwards
Check the reliability of the evidence
Change the theory to match the new evidence
