This UVA Speaks podcast features Kelsey Johnson, Professor of Astronomy and Associate Dean of Undergraduate Education at the College and Graduate School of Arts & Sciences at the University of Virginia. Earlier this year, Johnson captivated audiences at a popular Lifetime Learning virtual event entitled "Mysteries of the Cosmos: Science, Philosophy, and the Big Questions," where she delved into some of life's most profound mysteries. Due to the large number of questions posed by participants, Johnson agreed to address additional inquiries in this podcast. Here, she tackles deep questions about the origins of the universe, the nature of time, and the possibility of other dimensions. Johnson underscores the importance of curiosity and humility when confronting such vast and potentially unanswerable questions, and she champions interdisciplinary thinking as essential for fostering innovation and breakthroughs.
