 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

3. Stars and galaxies emit different types of electromagnetic waves 5 mins 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
