报告摘要 (Abstract):
We present a dynamical toy model for an expanding universe inside a black hole. The purpose of the model is to suggest a possible reconciliation
between the observation that black holes are well described by the classical solutions and the fact that the theoretical resolution of space-time
singularities leads to a bounce for the collapsing matter.
报告人简介 (Bio): I grew up in Assam, a state in India's northeastern frontier famous for it's tea. After graduating from high school,
I joined the integrated Masters program at Tezpur University. I graduated with specialization in Astrophysics and Cosmology in 2016, and
I worked on inflationary cosmology towards my masters' thesis. After teaching for a year in my hometown, I joined Prof. Cosimo
Bambi's group at Fudan University. Now my broad area of interest is classical and quantum aspects of gravity and particularly I
like working on solutions of Einstein's and modified/extended gravity theories and testing their properties. In my free time, I
like to enjoy a book with a fine cup of tea.
