Gott Time Machines, BTZ Black Hole Formation, and Choptuik Scaling
Danny Birmingham, Siddhartha Sen
TL;DR
It is shown that the Gott time machine, originally constructed for the case of vanishing cosmological constant, provides a precise mechanism for black hole formation, and one obtains an exact analytic understanding of the Choptuik scaling.
Abstract
We study the formation of BTZ black holes by the collision of point particles. It is shown that the Gott time machine, originally constructed for the case of vanishing cosmological constant, provides a precise mechanism for black hole formation. As a result, one obtains an exact analytic understanding of the Choptuik scaling.
