O volume de um buraco negro

Abstract

In this work will treated about the origins of the term Black Hole, and how our knowledge evolved, showing at the end one peculiarity about them, that the volume will vary depending with the definition of space used. Firstly will be treated about the vision of John John Mitchell and how he ”demonstrated” the Schwarzschild’s radius using Newtonian physics, then a discussion about the origins of the name ”Black Hole” by John Wheeler and an explanation of how the Black Holes are created and in which conditions this occurs. A discussion about how we can define a metric and how from it we can evaluate the volume of objects definied in the space described by the metric, if the metric is Riemannian. Lastly a discussion about each metric analyzed with its advantages, with their respective volumes evaluated, coming to the conclusion that the volume will depended directly of how the 3-space is defined.
