The Nobel Prize in Physics 2020 was divided, one half awarded to Roger Penrose "for the discovery that black hole formation is a robust prediction of the general theory of relativity", the other half jointly to Reinhard Genzel and Andrea Ghez "for the discovery of a supermassive compact object at the centre of our galaxy."
Speakers:
Dr. T. Ibungochouba, Dept. of Mathematics, MU, will speak the first part and
Dr. N. Chandrachani, Dept. of Physics, MU, will speak the second part.
1. Title: Exploring the black holes by Dr. Ningombam Chandrachani
The 2020’s Nobel Prize in Physics has been shared by the three Laureates for the discovery of one of the most exotic phenomena in our universe called the black hole. In this talk, I will be talking about the black holes mainly on the contributions made by Reinhard Genzel and Andrea Ghez, “the observational discovery of a supermassive compact object at the centre of our Milky way galaxy”.
2. Title: Newman-Penrose Formalism by Dr. T. Ibungochouba Singh
The Newman–Penrose formalism is a set of notations developed by Ezra T. Newman and Roger Penrose for general relativity. Their notation is an effort to treat general relativity in terms of spinor notation, which introduces complex forms of the usual variables used in general relativity. The Newman–Penrose formalism is itself a special case of the tetrad formalism, where the tensors of the theory are projected onto a complete vector basis at each point in spacetime.
The Newman and Penrose formalism can transform the complex equations namely Dirac equation and Maxwell’s electromagnetic filed equations into simpler forms which can be easily solved to study black hole singularity.
The most unavoidable occurrence in the general relativity is the singularity of black holes. The Raychaudhuri Equation in General Relativity, derived by Raychaudhuri is in the spotlight after 2020 Physics Nobel was awarded to Penrose for throwing light on Black Holes.
