Document Summary

Section 1: from the big bang theory to the birth of the planet. All energy was concentrated in an infinitely small volume estimated13. 7 bya. Universe was all energy no matter, infinitely hot. The universe is continually expanding universe cools as it expands. Doppler effect you hear a higher frequency when noise making object is moving towards you. In the visible spectrum, blue light has a high frequency, and red light has a low frequency. If the object were coming toward you, there would be a blue shift. If the object were moving away from you, there would be a red shift. Absorption spectrum of h= wavelengths of light at which h absorbs light. Point spectrometer at star the absorption spectrum of h shifts virtually all galaxies are red shifted everything is moving away from us. Hubble and the age of the universe v = hd v = d/t t = 1/h. Hubble wanted to estimate the age of the universe.
