Hey there! I'm a second year physics grad student and I've been asked to give a 30 minute presentation to my department on something about cosmology or a cosmology-like topic. I've been hunting the archive for weeks and I can't find anything too interesting (that I can understand) to talk about. The "that I can understand" is key. I'm going to need to understand what I'm talking about in order to present it, of course, but seeing that I'm only a second year (my first year consisted of studying for the qual) I don't have much of a deep background yet to really grasp most of the concepts in those papers. Does anyone know of any new interesting ideas related to cosmology that someone of my background would be able to understand enough to give a presentation on? Any suggestions would be GREATLY appreciated! Thanks for your time!
