Interview with Dr. Gary Hinshaw

of Goddard Space Flight Center is now online and available here. Dr. Hinshaw was kind enough to discuss the Cosmic Microwave Background (CMB), an invaluable source of information on the nature of the universe <1 million years after the Big Bang. (In fact, the existence of the CMB is one of the major pieces of evidences which argues for the occurrence of the Big Bang). For more information on this subject, check out this interview I did with Dr. Daniel Babich (Cal Tech), as well as the following webpages:

  • Universe 101: Big Bang Theory - A review of the Big Bang theory and why astronomers think it is correct
  • Legacy Archive for Microwave Background Data Analysis - an archive of past and present measurements of the CMB
  • Cosmic Background Explorer - Information on the first satellite to measure temperature differences in the CMB between different regions on the sky
  • Wilkinson Microwave Anisotropy Probe - the most recent satellite to measure the temperature structure of the CMB, and is largely responsible for the era of "precision cosmology" - measuring the properties of the universe to better than a factor of 10 - which most Astronomers believe we have finally entered. In addition to information on this mission, there are a lot of good, general descriptions about cosmology on this website.
Hope you enjoy, and please email me or leave any questions below. Thank you for listening!
