Alan Guth
Early Life and Education
Alan Harvey Guth was born on February 27, 1947, in New Brunswick, New Jersey. He attended the Massachusetts Institute of Technology (MIT), where he received his bachelor's and master's degrees in physics in 1969. Guth continued his studies at MIT, earning his Ph.D. in physics in 1972.
Career and Research
Guth's early career was marked by a series of temporary jobs, including positions at Princeton University, Columbia University, Cornell University, and the Stanford Linear Accelerator Center (SLAC). During this time, he studied particle physics and attempted to understand the basic forces of the universe.
In 1979, while at Cornell, Guth first proposed the idea of cosmic inflation, a modification of the standard Big Bang theory. This theory suggests that the universe underwent a period of rapid expansion in the moments after the Big Bang, explaining several puzzling aspects of the universe's current state.
In 1980, Guth moved to MIT, where he has remained ever since. He is currently the Victor F. Weisskopf Professor of Physics at MIT.
Cosmic Inflation
Guth's theory of cosmic inflation proposes that the universe expanded exponentially fast in the first fraction of a second after the Big Bang. This rapid expansion smoothed out the universe, explaining why it appears to be roughly the same in all directions.
Cosmic inflation also provides a mechanism for the generation of cosmic microwave background fluctuations, which are small variations in the density of the universe that later grew into galaxies and large-scale structures.
The theory of cosmic inflation has been supported by a wide range of observational evidence, including measurements of the cosmic microwave background by the Planck spacecraft and studies of the large-scale structure of the universe.
Honors and Awards
Over the course of his career, Guth has received numerous awards and honors for his contributions to theoretical physics. These include the Eddington Medal from the Royal Astronomical Society, the Dirac Medal from the International Centre for Theoretical Physics, and the Fundamental Physics Prize from the Milner Foundation.
In 2014, Guth was awarded the Kavli Prize in Astrophysics, shared with Andrei Linde and Alexei Starobinsky, for their work on the theory of cosmic inflation.
Personal Life
Guth is married to Susan Tisch Guth. They have two children, Lawrence and Jennifer.
