Black Hole

To deepen our appreciation of the cosmos, Dr. Quataert, a professor in the Astronomy Department at UC Berkeley will talk about black holes, a subject of interest to everyone with a love of the frontier between science and science fiction. As well, we will see the truly visionary art of astronomical painter and computer artist, Geoffrey Chandler.

Black Holes
Dr. Eliot Quataert will begin by describing what black holes are (and what they are not!). He will then discuss how black holes are discovered and how they give rise to some of the most remarkable and bizarre phenomena in the universe. No background in science will be required for the lecture.
Theoretically, a black hole is a singularity in space-time, a mathematically precise point into which all the mass has been squeezed. This singularity can never be seen, however, because it is surrounded by a spherical region into which all infalling matter disappears and from which nothing, not even light, escapes. Black holes existed in the imagination of mathematical cosmologists until 1971, when Cygnus X-1 was identified. Two decades ago, when University of California, Berkeley physicist Charles Townes and his colleagues, including post-doc Reinhard Genzel, claimed to have evidence for a massive black hole at the center of the Milky Way, few believed them….Now, it turns out, Townes and Genzel were right!

Quataert is a highly regarded teacher and public lecturer. He is one of the leading scientists studying how black holes are formed, the effects of black holes on their surroundings, and how black holes reveal themselves when hot gas from the neighborhood falls into them

Cosmic Art
Cosmic art by Geoffrey Chandler will be shown. San Francisco artist Geoffrey Chandler is considered one of the world’s most renowned astronomical artists. In March, 1987 his work was on the cover of Time magazine, and has been widely seen on album covers, posters and book covers. The Oakland Museum, the California Academy of Sciences, San Jose Museum of Art and The Rosecrucian Museum have been some of the sites for his solo shows. Chandler’s painting show that he is in love with the cosmos – in all its majestic grandeur, colossal power, and ethereal beauty. His more recent computer works are an intoxicating blend of “science, math, the spiritual, and the universe”.
