1999-2009, key results "look back" in string & LQG
In the news there is a lot of "past 10 years", from Bush v.s Gore and 9-11, to Iraq and electing first Black President, to death of Michael Jackson. The first possibly promising trial of HIV vaccine.
While 10 years is arbitrary, from 80's was the first superstring revolution, beginning of LQG, and 90s, second superstring revolution and A. 90s also saw evidence and measurement of cc, that we live in deSitter spacetime. AdS/CFT correspondence.
Tevatron in the past 10 years has NOT found Higgs and SUSY. LHC was delayed, the hope from the 90s was that LHC would be online and start producing data (well that and SCSC which was cancelled)
Past 10 years has seen a tremendous growth of blogs, and two, Not Even Wrong and Lubos Motl are quite central to LQG v.s strings this decade. If we restrict ourselves to 2000-2009, what are some of the most important results and developments in LQG? What about string theory? What observations may have most influenced the development of either?
For example,
Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope 21 Aug 2007 implies or suggestions that lorentz invariance is violated, BUT
Fermi Gamma-ray Space Telescope implies lorentz invariance stands September 2008.
A string paper that shows it is possible to get de Sitter space
de Sitter Vacua in String Theory http://arxiv.org/abs/hep-th/0301240
Authors: Shamit Kachru, Renata Kallosh, Andrei Linde, Sandip P. Trivedi

resulted in landscape of 10^500 backgrounds, and discussion over landscape and multiverse.Most of the research in LQC has been done this decade, including research on resolving singularities, showing big bounce, and even with inflaton field, showing inflation necessary.
