Research in theoretical physics and astrophysics will concentrate on studies of cosmic topological defects and quantum cosmology. The topological defects can include strings, domain walls, and other structures which can help solve the riddle of how "lumps" such as galaxies formed out of a very smooth early universe. Quantum cosmology is an effort to understand the nature of the big bang, and in particular the very first instant of the universe.

理论物理和天体物理的研究将集中在宇宙拓扑缺陷和量子宇宙学的研究上。拓扑缺陷可以包括弦、畴壁和其他结构，这些结构可以帮助解决诸如星系之类的“团块”如何从非常光滑的早期宇宙中形成的谜团。量子宇宙学致力于理解大爆炸的本质，尤其是宇宙形成的最初瞬间。
