9511632 Weinberg String theory is an attempt to move beyond the quantum mechanical description of elementary particles as point like particles to a formulation of them as excitations of a microscopic string-like objects. These excitations would include not only quarks, gluons, leptons ,etc., but also the graviton, the quantum excitation of gravity so that one would have a truly unified theory of all interactions. One aim of this research is a better and deeper understanding of space-time and a quantum theory of gravity. A second aim is to explore the links of such a theory to conventional particle physics as described by the standard model and its implications for astrophysical and cosmological measurements. ***

9511632温伯格弦理论是一种尝试，试图超越基本粒子作为点状粒子的量子力学描述，将它们描述为微观弦状物体的激发。这些激发不仅包括夸克、胶子、轻子等，还包括引力子，即引力的量子激发，这样人们就会有一个关于所有相互作用的真正统一的理论。这项研究的目的之一是更好和更深入地理解时空和引力的量子理论。第二个目标是探索这种理论与标准模型所描述的传统粒子物理的联系及其对天体物理和宇宙学测量的影响。***
