Sometimes folks at forum venture the opinion that Quantum Geometry (=gravity) effects cannot be seen except at prohibitively high energies, leading them to conclude that QG research cannot reasonably expect guidance from experiment and observation. Generally speaking I think this is mistaken. I see a lot of phenomenological work which however mostly has to do with observational astronomy---what we can see and tell about the early universe: the Cosmic Microwave Background and evidence of an inflationary era or bounce. Nevertheless some researchers are more focused on the experimental side of the equation. Next month (October 2012) there will be a conference emphasizing that. http://www.perimeterinstitute.ca/en/Events/Experimental_Search_for_QG/Experimental_Search_for_Quantum_Gravity%3A_the_hard_facts/ [Broken] Since it is being held at Perimeter we can expect to be able to watch some of the presentations as online video, and it may teach us something. So this thread is about preparing for that. I will list the participants---most will be known to regulars at this forum and that will give an idea of the range of topics. There is also a kind of "mission statement" worth studying, I think, on the conference home page.
