FIRST EDITION IN ORIGINAL WRAPS of Alan Guth's landmark paper introducing the concept of "cosmic inflation," a new cosmological model he called 'inflation theory'. Though just a theory for 30 years, Guth's paper "utterly transformed scientific thinking about the origin of the universe" (Focus: Landmarks, The Inflationary Universe). In March 2014, scientists found what they say is the first direct evidence of Guth's inflation. "From studying the cosmic microwave background (CMB -- the leftover radiation from the big bang -- they have spotted traces of gravitational waves -- undulations in the fabric of space and time -- that rippled through the universe in that infinitesimally short epoch following its birth. The imprint of these gravitational waves upon the CMB matches what theorists had predicted for decades. The findings... also show that gravity -- at the smallest scale -- follows the rules of quantum mechanics [in ways] similar to other forces such as electromagnetism" (Science Magazine Online). In importing new ideas from particle physics into theoretical cosmology, Guth alters conventional big bang theory, offering essentially, a bigger, faster bang. "The classic Big Bang theory," Guth explains, "˜says nothing about what banged, what happened before it banged, or what caused it to bang" (Guth). "Inflation theory suggests a superfast early-universe expansion in a tiny sliver of a second of time, the explosion driven by gravitational repulsion, the repulsion of matter and antimatter, which stretched the universe toward its present size and scale unimaginably faster than conventional cosmology had predicted. Earlier accounts of the big-bang theory depicted a universe that cooled so quickly it prevented homogeneity, but Guth's period of inflation establishes a period of time before the big bang, when the universe was small enough to evenly distribute its contents. The inflationary universe model seems to more accurately explain the spectrum of density fluctuations that gave rise to the rapid expansion that created the universe as we know it" (NNDB). As the result of Guth's research and the findings of March, 2014, cosmologists now think the just-born universe -- "a hot, dense soup of matter and energy -- went through a burst of expansion faster than the speed of light. Like a magical balloon, the cosmos doubled its size 60 times in a span of 10 (-32) seconds. This phase [Guth's inflation] ended well before the universe was even a second old" (Science Magazine Online). Fine in Original Paper Wraps. Item #1307
