General Meeting: Open to the Public
Sunday, February 12, 2017 at 2 p.m.
Muhlenberg College, Trumbower Rm. 130 (Lithgow Science Auditorium)
Black Holes, Strings and Holography
Sera Cremonini, PhD,
Assistant Professor of Physics, Lehigh University
The recent announcement of the direct detection of gravitational waves provides yet another remarkable confirmation of Einstein's vision of the universe, in which space and time are interwoven and dynamic. Despite its stark successes, the theory of general relativity is incomplete, in that it fails to describe regions of space-time with very large curvature, and for which quantum mechanical effects cannot be ignored. These include the interior of black holes and the very early universe. String theory, our leading candidate for a quantum theory of gravity, offers a concrete framework to probe the microscopic properties of black holes and the short-distance behavior of space-time. It has also lead to remarkable new insights into the connection between gravity and the quantum mechanical world. This lecture will discuss various aspects of string theory and what it has taught us about the nature of gravity.
A native of Cremona, Italy, Sera moved to the US after high-school. She earned her undergraduate degree in Physics and Mathematics from The City College of New York (CUNY), her Masters from Columbia University, and her PhD from Brown University. Before joining Lehigh University in 2015 as an Assistant Professor in Physics, she held a position with The Michigan Society of Fellows, University of Michigan, Ann Arbor, and a joint position between Cambridge University and Texas A&M University
