Portland State University Big Bang Theory Inflation of Universe Paper

Portland State University Big Bang Theory Inflation of Universe Paper

Why is inflation necessary to explain our universe and how does inflation solve the flatness and horizon problems?
In the standard model of cosmology (excepting accelerated expansion) there are three possible fates for the universe. For each fate, state the geometry (shape) of the universe (sphere, saddle, flat), the ulimtate fate of the universe (expand forever, expand forever ever-slowing, big cruch), and how the critical density compares with the actual density of the universe (greater than critical, less than critical, equal to critical).
Explain the fates of a low-mass star like the Sun and a high-mass star like Rigel. Make sure to state the final elements produced during their lives and the identity of their ultimate stellar remnants.
give three pieces of evidence that support the Big Bang model of the universe. State each piece and give a brief description why it supports the Big Bang model.
