Origin of the Solar System-big bang-universe started in hot tiny space, expanded as result of BB-continuing to expand from big bang-came up with theory by studying properties of light-red shift-cosmic microwave background-red shift-hubble created hubble law-by looking at light from starts, was able to correlate distance of star from earth and what stars were made of-able to create spectrum of light from stars-light of stars like Doppler effect-farther away caused light to turn red red shift-moving towards blue shift, light turned blue-fratehr away the star, faster away star is moving implies universe expanding-hubble law recession speed = Ho x distance-could find age of universe by finding distance of stars-since universe was originally in tiny space-supports age of 13.5 Ga for universe, expanding for 13.5 Ga -light shifted red from further galaxies-cosmic microwave background (CMB)-recombination, 380,000 years after BB-universe cooled enough to allow protons and electrons to form atoms-evidence CMB-scientists discovered ambient radiation in universe-radiation was everywhere-photons leftover from 380k ABB still bouncing around everywhere-CMB -Penzias and Wilson built horn antenna discovered CMB-afterglow of big bang-released a glow of photons-supports an age of 13.7 Ga for universe and supports red shift calculations-temp differs in photon field by only about .0002 kelvin-photons still bouncing a
