### From Falling Apples to Collapsed Stars: A Brief History of Black Holes

Thursday, Oct. 10, 7-9 p.m.

Johnson Geo Centre, 175 Signal Hill Rd.

What exactly is a black hole, and how does one try to contend with an object that, by definition, cannot be seen or heard?

In this introductory talk, Dr. Hari Kunduri will outline some of the basic ideas behind Einstein’s theory of general relativity. Black holes are in some ways the most elementary objects in Einstein’s theory. Dr. Kunduri will give an idea of the progress we have made in understanding them over the last 100 years.

**About the Lecturer:**

Hari grew up in Northern Ontario, he later completed his undergraduate degree in physics and mathematics at the University of Toronto. From there he went to the University of Cambridge to complete a Ph.D in theoretical physics. After holding research fellowships at Cambridge and the University of Alberta, he moved to the mathematics department at Memorial in 2011. His research concerns mathematical and theoretical aspects of black holes in general relativity and string theory.

*Admission is $5 and supports educational programming.*
