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.

引力是自然界的基本力之一，它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地球上的重力。 最极端的情况：在黑洞和中子星的碰撞过程中。只 通过这些计算，我们可以了解时空在弯曲时的行为， 被黑洞围绕着旋转这些计算的结果然后用于测量 我们宇宙中黑洞的引力波，并破译它们的含义： 我们将了解宇宙中有多少黑洞，它们的位置，以及它们的位置。 重要的属性，如大小和旋转。
