General Relativity 2 - Gravity is a Curvature
Speaker(s): Michael Burns
Abstract: Spacetime tells matter how to move, and matter tells spacetime how to curve.
Learning Outcomes:
• Why gravity can be seen as a curvature of spacetime.
• That Einstein’s field equations describe how matter curves spacetime.
• How Sir Arthur Eddington verified Einstein’s theory of general relativity by measuring the change in position of stars during a solar eclipse.



General Relativity 3 - Who's Who in the Story of Black Holes
Speaker(s): Michael Burns
Abstract: An introduction to a few of the major scientists who applied Einstein's ideas to better understand the life cycle of various stars.
Learning Outcomes:
• How Subrahmanyan Chandrasekhar resolved the paradox of the white dwarf star, and how Walter Baade and Fritz Zwicky described the dynamics of neutron stars.
• Yakov Zel'dovich develops the nuclear chain reaction that is the engine that keeps stars burning.
• The roles Robert J. Oppenheimer , John Wheeler, and Roger Penrose played in moving the concept of a black hole from a object of pure theory to a physical object in the universe.



General Relativity 4 - The Life Story of Stars
Speaker(s): Michael Burns
Abstract: The mathematical predictions made by scientists tell a story of the life and death of stars.
Learning Outcomes:
• How the Hertzsprung-Russel diagram describes the life cycle of stars.
• Depending on its mass, how a star ends its life as a white dwarf star, a neutron star, or a black hole, and where super novas fit in.
• How the mathematical predictions of white dwarf stars, super novas, and neutron stars are slowly verified by the advancement of the astronomical equipment used by astronomers.



General Relativity 5 - The Black Hole
Speaker(s): Michael Burns
Abstract: The anatomy of a black hole.
Learning Outcomes:
• What are the mass requirements for a star to become a black hole?
• The anatomy of a Schwarzschild black hole, including the singularity and the event horizon.
• What a traveller would experience if he orbited a black hole, or had the bad luck to fall through the event horizon.



General Relativity 6 - The Star Called a Black Hole
Speaker(s): Michael Burns
Abstract: The physical attributes of a black hole and what types of physical evidence astronomers use the locate them.
Learning Outcomes:
• What are the physical requirements for a star to become a black hole, and what properties of that star remain after the black hole is formed?
• The types of black holes, including: the Schwarzschild black hole, the Reissner-Nordström black hole, the Kerr black hole, and the Kerr-Newman black hole.
• What a traveller would experience if he orbited one of these more general black holes, or fell through to the singularity.
