Alan Guth's work from 1979 - 1981 suggested what we now call eternal inflation is the best-fit explanation for the universe we see, and the 2006 results from the WMAP mission provided evidence strongly suggesting his work is validated by empirical data. Although the Nobel committee has, as is so often the case, failed to recognize the importance of his work, the 2014 award of the Kavli prize is a significant acknowledgement. Considering that Guth's hypothesis resulted from an attempt to explain the absence of magnetic monopoles in the early universe, we have to consider it a tour-de-force almost comparable to the great cosmological revolutions of the past.
