Linde and Guth eventually exchanged papers on the subject. By 1983 Guth had published a paper describing how his supercooled universe scenario was not ideal, as the "triggering mechanism" to exit such a state would require "extreme fine tuning of parameters" and felt a more natural solution was required. However, this did not deter him from the belief that the universe expanded exponentially in a vacuum in its early lifetime. In the past Guth has studied lattice gauge theory, magnetic monopoles and instantons, Gott time machines, and a number of other topics in theoretical physics. Much of Guth's current work includes extrapolating density fluctuations arising from various versions of inflation, to test against observations, and investigating inflation in "brane world" models. Guth is the Victor F. Weisskopf Professor of Physics at the Massachusetts Institute of Technology (MIT). So far, he has written about 60 technical papers related to the effects of inflation and its interactions with particle physics. He has won many awards and medals, including the Medal of the International Center for Theoretical Physics, Trieste, Italy, with Andrei Linde and Paul Steinhardt and the Eddington Medal in 1996, and the 2009 Isaac Newton Medal, awarded by the British Institute of Physics. In July 2012, he was an inaugural awardee of the Fundamental Physics Prize, the creation of physicist and internet entrepreneur, Yuri Milner. In 2014, he was a co-recipient of the Kavli Prize awarded by the Norwegian Academy of Science and Letters, together with Andrei Linde of Stanford University, and Alexei Starobinsky of the Landau Institute for Theoretical Physics, "for pioneering the theory of cosmic inflation." In 2005 Guth won the award for the messiest office in Boston, organised by the Boston Globe. He was entered by colleagues who hoped it would shame him into tidying up, but Guth is quite proud of the award.
