BEYOND SINGULARITY: how to become a black hole Pedro L. F. lime; Julia G. M. pontes; Mary E. lime RESUMO Este artigo explora os buracos negros, cosmic entities whose gravity is so intense that not even light - a body which has maximum speed - can escape its attraction, and the metaphorical reflection of how to turn a human being into a black hole. Consequently, we developed an application that calculates what the person's “size” should be in order for them to become this dense body. For such, physics concepts will be explained, such as escape velocity and Schwarzschild radius, which are used in the calculation. Key words: Schwarzschild; Escape velocity; Relativity. 1. INTRODUCTION Black holes are, undoubtedly, one of the most mysterious and intriguing phenomena in the universe. Originated from the death of massive stars, These bodies challenge our understanding of physics by concentrating enormous amounts of mass into an infinitely small point, called singularity. Such regions of space-time have been studied since the 17th century., However, a more precise study was only possible with the advent of the theory of general relativity., formulated by Einstein in 1915. In less than two months after its publication, German physicist Karl Schwarzschild found a solution to Einstein's equations. Such a solution reveals the existence of a critical radius, called Schwarzschild radius: objects which have a radius smaller than this are called black holes. We will use the concepts presented in the application so that it can “transform” a normal person into a black hole. 2. THEORETICAL BASIS To build the application's programming logic, one must understand what escape velocity is and what its relationship is with black holes, such reflection culminates in the understanding of the Schwarzschild radius. Imagine that you throw an object of mass m upwards, inevitably he will fall, due to the Earth's gravitational force. S
