Astronomical observations probing the earliest moments of the big bang are being used to learn about the interactions of subatomic particles at the shortest possible distance scales. String theory is the only known model which consistently unifies all the fundamental forces of nature. Although current particle physics experiments do not have enough energy to directly test string theory, we are looking for its imprints on the microwave radiation left over from the big bang. Our research explores the links between the period of superfast expansion in the early universe, called inflation, and string theory, which could lead to evidence in the cosmic microwave radiation.

探测大爆炸最早时刻的天文观测被用来了解亚原子粒子在尽可能短的距离尺度上的相互作用。 弦理论是唯一已知的能够一致地统一自然所有基本力的模型。 尽管目前的粒子物理实验没有足够的能量来直接检验弦理论，但我们正在寻找它在大爆炸留下的微波辐射上的印记。 我们的研究探索了早期宇宙超快膨胀时期（称为暴胀）与弦理论之间的联系，这可能会为宇宙微波辐射提供证据。
