Alan H. Guth (born February 27, 1947) is a physicist and cosmologist. Guth has researched elementary particle theory (and how particle theory is applicable to the early universe). February 27 is the 58th day of the year in the Gregorian Calendar. ... 1947 was a common year starting on Wednesday (link will take you to calendar). ... A physicist is a scientist trained in physics. ... Cosmology is the study of the large-scale structure and history of the universe. ... In particle physics, an elementary particle is a particle of which other, larger particles are composed. ... A particle is Look up Particle in Wiktionary, the free dictionary In particle physics, a basic unit of matter or energy. ... The deepest visible-light image of the cosmos. ...

As a junior particle physicist, Guth first developed the idea of inflation in 1979 at Stanford University after attending a Big Bang lecture by Robert Dicke. In 1981, Guth formally proposed the idea of cosmic inflation, the idea that the nascent universe passed through a phase of exponential expansion that was driven by a negative vacuum energy density (positive vacuum pressure). 1979 is a common year starting on Monday. ... For other meanings of Stanford, see Stanford (disambiguation). ... According to the Big Bang theory, the universe originated in an extremely dense and hot state (bottom). ... Robert Henry Dicke (May 6, 1916 – March 4, 1997) was an American physicist and astrophysicist. ... 1981 is a common year starting on Thursday of the Gregorian calendar. ... Inflation is the idea—first proposed by Alan Guth (1981)—that the nascent universe passed through a phase of exponential expansion (the inflationary epoch) that was driven by a negative pressure vacuum energy density. ...

Guth is the Victor F. Weisskopf Professor of Physics at the Massachusetts Institute of Technology (MIT). He won the Eddington Medal in 1996. The Massachusetts Institute of Technology, or MIT, is a research and educational institution located in the city of Cambridge, Massachusetts, USA. MIT is a world leader in science and technology, as well as in many other fields, including management, economics, linguistics, political science, and philosophy. ... The Eddington Medal, named after Sir Arthur Eddington, is awarded by the Royal Astronomical Society nominally once every two years for investigations of outstanding merit in theoretical astrophysics. ... 1996 is a leap year starting on Monday of the Gregorian calendar, and was designated the International Year for the Eradication of Poverty. ...
