1. Evidence for the Universe
Doppler Effect
-For stars, scientists notice red shift of light in stars and of light coming from galaxies
*note: red shift does not mean that everything will be red colored; it only means stars’ spectra are moving towards the red end of the spectrum

2. Evidence for the Universe
Cosmic Background Radiation (CMB)
-shows traces of energy in early universe which shows beginning have been very, very hot and dense and has cooled down since
-if universe is expanding, universe expected to get cooler

3. Evidence for the Universe
Composition of the Universe
-in terms of elements, the universe is made of mostly hydrogen (74%) and helium (25%) based on spectral analysis of matter in the universe
-helium can only form from hydrogen under certain hot, high pressure conditions
