Erast Borisovich Gliner (January 26, 1923 – November 16, 2021) was a Russian physicist specialized in cosmology. Gliner is best known for introducing the idea of cosmic inflation in 1965.
Life[edit]
He was born in Kyiv in 1923. His parents moved just three years laters to the city of Leningrad, where he spent his youth.[2]
He studied chemistry at the Leningrad State University. His studies were interrupted by the Second World War. During the war, he was wounded several times. The most severe wound led him to lose the right arm.[2]
After the war, he continued his studies. In 1963, he obtained a professor position at the Ioffe Institute in Saint Petersburg.[2]
After emigrating from the former Soviet Union in 1980 to the US, Gliner worked in cosmology and solar physics at University of Colorado, Boulder, and at the McDonnell Center for the Space Sciences and the Department of Physics at Washington University in Saint Louis.[1]
Work[edit]
In 1965, Gliner proposed a unique assumption regarding the early Universe's pressure in the context of the Einstein-Friedmann equations. According to his idea, the pressure was negatively proportional to the energy density. This groundbreaking relationship between pressure and energy density served as the initial theoretical prediction of dark energy, a phenomenon later confirmed by observational evidence.[3]
One year later, in 1966, Erast Gliner demonstrated that Einstein's equations could give rise to objects that outwardly resembled black holes but were, in reality, massive spheres of vacuum energy. If these hypothetical objects existed, it would imply that dark energy is not uniformly distributed throughout space but rather concentrated in specific regions, particularly the interiors of black holes. Even within these localized regions, dark energy would still exert its space-stretching influence on the Universe.[4]
