Free Virtual Talk All About Black Holes

The Stockton Astronomical Society presents
Black Holes: Space Warps, Time Machines, and the Gruesome Deaths of Stars
A nontechnical illustrated talk by Prof. Andrew Fraknoi
Free and open to the public via Zoom.
Although black holes have become part of our movies and our everyday language, few people really understand the exciting science ideas behind the science fiction. You will learn why falling into a black hole is definitely a once-in-a-lifetime experience, how black holes make a serious kind of time machine possible, and how new instruments have allowed astronomers to detect the presence of these elusive dark objects in our Galaxy and beyond. No background in science will be required or assumed.
These days, Andrew Fraknoi teaches non-credit courses for retired adults through several universities in Northern California. He is the lead author of the free, online book "Astronomy," published by the nonprofit OpenStax project, which has become the most frequently-used introductory astronomy textbook in North America. In recent years, he has had 11 astronomically-oriented science-fiction stories published in anthologies and magazines. He served as Executive Director of the Astronomical Society of the Pacific for 14 years, and was selected California Professor of the Year in 2007. The International Astronomical Union has named Asteroid 4859 Asteroid Fraknoi, in recognition of his contributions to the public understanding of science.
