These strings produce all known forces and particles in the universe, thus reconciling Einstein s theory of general relativity (the large) with quantum mechanics (the small).

这些“弦”制造了所有已知作用力和宇宙中的粒子，从而达到与爱因斯坦相对论(宏观)与量子力学(微观)理论的协调。

Since we don t have a complete understanding of string theory, it s impossible to rule out all possible models that are based on strings, said Rothstein.

罗斯丁说，“由于我们没有完全理解弦理论，因此不能排除基于弦的各种可能模式。”

These cosmic strings are predicted by most models of the universe, such as the string theory wherein two kinds of “strings” are unrelated.

大部分宇宙模型都有预测宇宙弦，比如弦理论里两种互不相干的“弦”。

In string theory, the forces and particles of which the universe is now composed are actually vibrations of tiny strings made from these ten dimensions (six of which are confined to such strings, and thus are not perceivable in the human-scale world).
