The End of Space and Time
(Special Event)
We are used to visualizing space as a stage on which things move and time as a marker for the passage of events. Vijay Balasubramanian, professor of physics at the University of Pennsylvania, will describe how Einstein combined space and time into a dynamic entity called "space-time" that can warp and bend in response to matter, giving rise to the force of gravity. He will then discuss the emerging understanding of space and time as simply approximate descriptions of a much more complex underlying reality. In this picture, space and
time can appear out of, or disappear into, timless and spaceless voids.
