The recent discovery of gravitational waves from binary black holes, and neutron stars, has open up new possibilities to solve some of the greatest mysteries of the universe: the nature dark energy, dark matter, and gravity at the highest scales, namely, quantum gravity. The project will explore possible tests of fundamental theories of gravity, such as string theory, using gravitational waves. More concretely, the project aims at addressing questions such as the following:Can the presence of additional dimensions be detected at future interferometers and if not, what can we learn about these theories? Are gravitational memory effects in these theories modified, and be detected using gravitational waves? Are there any exotic objects predicted in these theories, and do these show up in the gravitational waves' production and evolution? The project aims at using analytical, as well as numerical and computational tools to address these questions and it will have some focus on the science of the Einstein Telescope, as well as other (current and future) gravitational wave experiments.

最近发现的引力波从双黑洞，中子星，开辟了新的可能性，以解决一些最大的宇宙之谜：自然暗能量，暗物质，和引力在最高尺度，即量子引力。该项目将探索使用引力波对引力基本理论（如弦理论）进行测试的可能性。更具体地说，该项目旨在解决以下问题：未来的干涉仪能否检测到额外维度的存在，如果不能，我们可以从这些理论中了解到什么？这些理论中的引力记忆效应是否经过修正，是否可以用引力波来检测？在这些理论中是否有任何奇异的物体被预测，这些物体是否出现在引力波的产生和演化中？该项目旨在使用分析以及数值和计算工具来解决这些问题，并将重点关注爱因斯坦望远镜的科学以及其他（当前和未来）引力波实验。
