One of the sessions at the April meeting of the American Physical Society (APS) will be on what replaces classic GR singularities (like bigbang or blackhole) when you move to a quantized theory. Abhay Ashtekar will discuss this from the Loop side. Gary Horowitz will discuss the String side of it. http://meetings.aps.org/Meeting/APR08/SessionIndex2/?SessionEventID=82743 This will be session B7 on the morning of 12 April. Will any PFer be there? Here's Ashtekar's abstract The next day Jorge Pullin will speak on Recent developments in loop quantum gravity. That will be session M7, on Sunday afternoon http://meetings.aps.org/Meeting/APR08/SessionIndex2/?SessionEventID=83486 Ashtekar and Pullin are invited speakers, giving relatively long presentations of 35 minutes. There will probably be a bunch of contributed talks---shorter in duration---on these and related topics, but I have only scanned the list of invited talks.
