- What is the cosmic microwave background radiation a
- What is the type of spectrum of the background radiation? What is the

- About when did the Big Bang supposedly occur?
- What was the universe like
for the first few million years after the Big Bang? How was the early universe
like the cores of stars shining today?
- Where did most of the hydrogen and helium in the universe come from? How
about the deuterium? Why did the early universe not continue the
nucleosynthesis process to heavier nuclei?
- How does the present abundance of deuterium provide a good constraint on

- What is the evidence for a Big Bang type of model for the universe and
for a universe that has evolved over time?
