An Evening with Brother Guy Consolmagno

When: Wednesday, April 22
Time: 7:00 pm–8:30 pm | Theater doors open at 6:30 pm
Where: Johnson Family Star Theater
Discover the human side of astronomy, from bold theories to spectacular missteps and the surprising lessons they leave behind.
Join Brother Guy Consolmagno, Director Emeritus of the Vatican Observatory and President of the Vatican Observatory Foundation, as he presents Discarded Worlds: Astronomical Ideas That Were Almost Correct.
Astronomy is more than just observing. To make sense of these observations, a good theorist blends knowledge, imagination, and a willingness to be wrong.
Throughout history, great thinkers have taken on this challenge and come close to correct. Ptolemy in ancient Rome, medieval bishops Oresme and Cusa, and 19th-century astronomers Schiaparelli and Pickering were all almost right in their interpretations. They were wrong in interesting ways, sometimes hilariously, sometimes heartbreakingly.
What can we learn from these discarded images of the universe?
