Notes From Reading Flashcards
who proposed the idea of the big bang?
Gamow = universe started at a point
who disagreed with Gamow?
Hoyle = he proposed the steady state theory which suggests the universe is infinite and that matter is being created all the time at just the right rate
evidence of the big bang theory?
if it was true, the beginning of the universe would have been VERY hot, therefore they were looking for some kind of proof of this heat.
A wavelength for the heat radiation was determined and then found by Wilson and Penzias = CMB (cosmic background radiation)
non-uniform CMB?
tells us the early universe was not uniform which is how everything was able to be formed. If it was uniform, there would be nothing
Inflation is…
initial stage that lasted about 10^-24 seconds where the universe expanded about 10^50 times in size = prevented collapse of initial universe, however, had inflation lasted any longer, it would have been too far apart and cold
Spectral types?
OBAFGKM = often beck angrily flies to Greenland killing moons
