Nonlinear interactions in general relativity will be studied using a code that simulates the implosion and re-explosion of a vacuum. axisymmetric gravitational wave. As the wave amplitude is increased, the wave begins to hold itself together (temporarily) by its own mass energy. If the amplitude is large enough a black hole will form and radiate off its asphercity. Another code, currently being tested against perturbation theory, is being developed specifically to study black hole spacetimes. It will be used to investigate the radiative properties of very highly distorted single black holes and eventually to simulate the head-on collision of two black holes and calculate the gravitational waves emitted.

广义相对论中的非线性相互作用将使用模拟真空内爆和再爆的代码进行研究。轴对称引力波。当波的振幅增加时，波开始通过自身的质能（暂时）将自己固定在一起。如果振幅足够大，黑洞就会形成，并从它的非球面向外辐射。另一个代码，目前正在测试与微扰理论，正在开发专门研究黑洞时空。它将用于研究高度扭曲的单个黑洞的辐射特性，并最终模拟两个黑洞的正面碰撞，并计算发射的引力波。
