Topic: The Fate of an Astronaut who falls inside a Black Hole - and the Fate of the Universe

Speaker: Dr. Lior M. Burko (UAH)

Date & Time: Thursday, January 12, 2006, 1:00 PM

Place: Room 140 VMC (Chambers Hall)



Two of the long-standing open questions in gravitation theory have been the fate of an astronaut who falls into a black hole, and the fate of the universe. Apparently, there is no close relation between these two puzzles: The in falling astronaut is usually believed to be utterly pulverized a short time after she crosses the black hole's event horizon; on the other hand, the cosmological time scale is very long. In this talk, I shall review these two puzzles, and hint at a possible connection between the two, such that an answer to one may yield also the answer to the other.



Dr. Burko received a PhD from Technion-Israel Institute of Technology in 1998. The thesis subject was: Nonlinear dynamics of spherical black holes. From 1999-2001, he held a postdoctoral position as a research scholar with Theoretical AstroPhysics Including Relativity (TAPIR) Group at the California Institute of Technology. He then joined the Department of Physics at the University of Utah where he was a Research Associate from 2001-2003 and later was appointed Research Assistant Professor (2003-2004). In 2004-2005, Dr. Burko was an Assistant Professor at Bates College. He is now an Assistant Professor at UAH. Dr. Burko's research interests include topics in general relativity, gravitational physics, gravitational-wave astrophysics, relativistic astrophysics, black holes, and cosmology with more than 44 refereed Journal publications.
