Dr. Alan H Guth,

Inflationary cosmology gives a very plausible explanation for many features of our universe, including its uniformity, its mass density, and the patterns of the ripples that are observed in the cosmic microwave background. Most versions of inflation, however, imply that our universe is not unique, but is part of a possibly infinite multiverse. Winner of the 2014 Kavli Prize in astrophysics, Dr. Guth was honored for pioneering the theory of cosmic inflation.
