Gravity, one of the fundamental forces of nature, is governed by Einstein's equations of general relativity. This research uses supercomputers to investigate gravity in the most extreme circumstances: during collisions of black holes and neutron stars. Only through these calculations can we learn how space-time behaves when it is warped and whirled around by black holes. Results of these calculations are then used to measure gravitational waves from black holes in our Universe and to decipher their meaning: We will learn how many black holes exist in the Cosmos, their locations, and their important properties like sizes and spins.

重力是自然的基本力之一，由爱因斯坦方程控制 广义相对论。这项研究使用超级计算机来研究重力 最极端的情况：黑洞和中子星碰撞期间。仅有的 通过这些计算，我们可以了解时空在扭曲时的行为方式 被黑洞旋转。然后使用这些计算的结果来测量 来自宇宙黑洞的引力波并破译它们的含义： 我们将了解宇宙中存在多少个黑洞、它们的位置以及它们的性质 重要的属性，如大小和旋转。
