Our Universe: The Known and The Unknown
Course Description:
A scientific theory of the universe began to emerge about 100 years
ago; it remains a work-in-progress. We explore many fascinating facts
about our universe--its size, its age, what it contains, and of what it
is made. What is expanding and what isn't, and what "Big Bang" and
"expansion" really mean. Where did our universe come from? What is its
future and how do we fit in? No prior scientific expertise required.
Classes will be recorded.
