http://www.arxiv.org/abs/astro-ph/0202008 Here is a good overview of cosmology describing the evidence for the present model, the open questions, and what ongoing observations can be expected to resolve over the next decade. The writing is rigorous and for fellow profesionals (no effort at popularization) but it is authoritative, broad-gauge, and concise, so it may be of use to some PF folk. The date is spring 2002 so it is fairly up to date. If you know of a better recent survey article at this level, please let me know. Here (down to the asterisks) is a sample exerpt copied from the first page: MAKING SENSE OF THE NEW COSMOLOGY Michael S. TURNER Center for Cosmological Physics Departments of Astronomy & Astrophysics and of Physics Enrico Fermi Institute, The University of Chicago Chicago, IL 60637-1433, USA NASA/Fermilab Astrophysics Center Fermi National Accelerator Laboratory Batavia, IL 60510-0500, USA Abstract: Over the past three years we have determined the basic features of the Universe--spatially flat; accelerating; comprised of 1/3 a new form of matter, 2/3 a new form of energy, with some ordinary matter and a dash of massive neutrinos; and apparently born from a burst of rapid expansion during which quantum noise was stretched to astrophysical size seeding cosmic structure. The New Cosmology greatly extends the highly successful hot big-bang model. Now we have to make sense of all this: What is the dark matter particle? What is the nature of the dark energy? Why this mixture? How did the matter--antimatter asymmetry arise? What is the underlying cause of in ation (if it indeed occurred)? *******end of quote********* What's your idea of a concise summary of where cosmology stands at present----the main evidence, the main results, conjectures etc. the focus for future research? The same view is available at various levels of sophistication. For example Ned Wrights cosmology tutorial covers a lot of the same ground but in a style that makes it highly accesible----certainly to undergrads and I would guess also to a lot of Highschoolers. Maybe I will add some links to Ned Wright pages to this thread. But mainly I would like to know what other people have found, at whatever level, that serves this purpose----especially if online and you give the links!
