National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Making Sense of the New Cosmology.

DE2003804700

Publication Date	2002
Personal Author	Turner, M. S.
Page Count	22
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 inflation (if it indeed occurred).
