The aim of this program is to achieve a better understanding of gravity, black holes, and the beginning as well as the evolution of the Universe. Black holes are regions of spacetime where matter is so dense that it literally forms holes in spacetime according to Einstein's General Relativity (GR) (the best theory of gravity we have today). I will examine more closely the evolution of black holes using one of theorists' favorite tools, called spacetime conformal mapping, for studying spacetime. This tool consists in changing the lengths and the duration of an event without changing the coordinates of that event. Since the thermodynamics and the mechanics of black holes are deeply intertwined, by studying the latter using this precious theoretical tool I will bring more light to the former.

该计划的目的是更好地理解引力，黑洞，宇宙的起源和演化。根据爱因斯坦的广义相对论（GR）（我们今天拥有的最好的引力理论），黑洞是时空中物质密度如此之大的区域，以至于它在时空中形成了洞。我将更仔细地研究黑洞的演化，使用理论家最喜欢的工具之一，称为时空共形映射，用于研究时空。该工具包括改变事件的长度和持续时间，而不改变该事件的坐标。由于黑洞的热力学和力学是紧密交织在一起的，通过使用这一宝贵的理论工具研究后者，我将为前者带来更多的光明。
