Guest Lecture by Pranav Sharma

We, humans, are a curious species. Our ability to ask questions about anything and everything has certainly assisted us in spurring our collective growth. And physics has been central to answering, or at least asking, some of our most fundamental questions about the cosmos. Students of DP-1 discussed some of these questions, as well as why we should ask them in the first place, in a webinar on black holes.

First, we were provided with some context on the birth of the universe and the big bang, which very much garnered some questions on why, where, or how exactly it had occurred. Getting the answers was much harder. We were also introduced to the two frameworks by which physicists model and explore the universe on Quantum mechanics and Relativity. Apart from learning the fundamentals of these models, we explored the individuals who worked and built upon them, widening our collective knowledge bit by bit.

After our brief discourse, we finally arrived at black holes. We were first asked what our perceptions of black holes were and why they differ from other celestial bodies. Our moderator provided an insightful analogy into black holes, citing them to be massive, but minuscule, weights on the fabric of space-time. But more importantly, we gained insight into why we study black holes in the first place. It’s precisely because our current models of the universe fail to explain them, prompting physicists to work towards more comprehensive theories that better explain the workings of the cosmos. Because the black hole is shrouded in mystery, they both entice us to ask questions and may help in answering them.
