Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as M

  • Abhay Ashtekar (Kolhapur, India, 5 de julio de 1949) es un físico indio. Ocupa la plaza de Profesor Eberly de Física y de Director del Instituto para la Física y Geometría Gravitacional en la Universidad Estatal de Pensilvania. Es el creador de las variables de Ashtekar y, a raíz de ello, uno de los fundadores de la gravedad cuántica de lazos (LQG, por sus siglas en inglés) y la subsiguiente cosmología cuántica de lazos (LQC).​ También ha escrito varios textos introductorios a la materia, dirigidos a gente sin conocimientos extensos de física. En 1999, Ashtekar y sus colegas consiguieron calcular la entropía de un agujero negro a partir del formalismo de LQG, obteniendo la predicción que hizo Hawking en 1974.​ Roger Penrose ha descrito la propuesta de gravedad cuántica de Ashtekar como "la (es)
