The successes of inflationary theory
in explaining special features of our universe are discussed.
7 billion years ago, create concerns about "the inflationary theory of the cosmos-the idea that space expanded exponentially in the first moments of time.
Planck had mapped the most detailed readings to date and seemed to confirm the inflationary theory about the universe - that the universe expanded extremely fast immediately following the Big Big before eventually slowing - which had been widely accepted by cosmologists for more than three decades.
Introduction to the theory of the early universe; cosmological perturbations and inflationary theory
Written for general audiences, this volume on the current theories surrounding the origins and evolution of the universe addresses such concerns as the validity of the Big Bang Theory, the inflationary theory
of universe expansion and recent debates over intelligent design.
As observers design ever more exacting tests, theorists are grappling with their own set of challenges--the principal one being that inflationary theory
is not really a theory at all.
The experiment showed that the geometry of space-time is very nearly linear or flat, as opposed to being curved, consistent with Inflationary theory
Similarly, when I first heard about the stunning success of the COBE (Cosmic Background Explorer) satellite in finding the anisotropy, or tipples in time, which indicated that the cosmos was still twitching from the initial effects of the big bang as predicted by inflationary theory
, it can be earnestly said that most of us were ignorant of what it was all about.
I shall not discuss the new ideas introduced by string theory (see, for example, Weingard  and Green et al ), the Hartle-Hawking wave-function theory, Guth's  original inflationary theory
, Linde's , Albrecht's and Steinhardt's  new inflationary theory
, Linde's  chaotic inflationary theory
, Tryon's , Gott's , Zeldovich's  and others vacuum fluctuation theories, and Dewitt's  grafting of Everett's many-worlds interpretation of quantum mechanics onto big bang cosmology.
Dark matter, the question of an open or closed universe, and inflationary theory
are all tackled successfully with style and grace.
Taking a page from inflationary theory
, the net energy of the sum total of all these multiverses would be exactly zero.
The amount of it supposedly measured accounts beautifully for the "missing" energy that the universe ought to have in order to make the inflationary theory
of the early Big Bang come out just right (S&T: September 1998, page 38).
