Blackholes are exotic objects whose gravitational pull is so strong that nothing (not even light) can escape from them!
How are these graceful bodies formed? Well, stars produce energy through the process of nuclear fusion, which converts hydrogen into helium. When a star with a mass more than about 30 solar masses exhausts its hydrogen fuel, it continues to collapse into a smaller and smaller structure and this crushing results in the formation of Blackholes. It is also believed that at the center of every galaxy, there is a supermassive Blackhole, which is millions of times bigger than the mass of the Sun. Moreover, the universe also has rotating blackholes, where the center black region is the Blackhole and the light unevenly surrounding it is basically an asymmetry caused due to gravity. Isn’t this world of blackholes interesting and worth exploring?
These entities are considered as the mathematical laboratories to study and analyze the fundamental laws of physics — in particular, the relationships between quantum theory and gravitation. It is widely believed that the detailed study of Blackholes will provide us with clues about the ultimate aim of theoretical physics, the unification of all forces, new laws of nature and pretty much, the theory of everything…
A detailed story on some captivating aspects of these objects was published on Medium which can be accessed here. It is based on one of the sessions (delivered by Sudipta Sarkar, faculty in the Physics discipline) of the Virtual Seminar Series by IIT Gandhinagar.
