Newton’s Model Infinite and static Olber’s paradox
Evidence of Expansion Hubble’s law –doppler shift –recession velocity Vs. distance
Evidence of Expansion Background radiation –doppler shift
The Creation of the Universe The big bang –time line 10 -43 s 10 -35 s 10 -35 s - 10 -24 s 10 -12 s 10 -6 s 2 s 3 minutes 300, 000 years
The Creation of the Universe The big bang –the laws of physics –where –when
The Fate of the Universe Critical mass / density
The Fate of the Universe Curvature of space –open (saddle or negative curvature) –critical (flat or no curvature) –closed (spherical or positive curvature)
Some say the world will end in fire. Some say ice. From what I’ve tasted of desire I hold with those who favor fire. But if I had to perish twice I think I know enough of hate To say that for destruction ice Is also great And would suffice.
Cosmology. Some important questions Did the universe have a beginning or has it always existed? Will the universe end? If it ends, what will happen at.
The Big Stuff Galaxies The Universe and The Big Bang.
Dark Energy. Conclusions from Hubble’s Law The universe is expanding Space itself is expanding Galaxies are held together by gravity on “small” distance.
“OUR GALAXY” Definition of a Galaxy: a huge group of individual stars, star clusters, dust, and gas bound together by gravity.
