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 the recent year, more and more physical problems on the noncommutative background are regarded as important for people with the study of the quantum Hull Effect and the string theory.

近几年，随着对量子霍尔效应和弦理论的研究，越来越多的非对易背景上的物理学问题引起人们的重视。

Just how many hidden dimensions exist depends on the theory, but some versions of the popular string theory for example, postulate we live in a 10 - or 11-dimensional universe.

究竟存在着多少隐藏的维度，这个问题仅依赖于理论，但流行弦理论的一些版本，作为例子，假设我们生活的宇宙，有10维或11维。

Most scientists outside the string theory community are philosophically uncomfortable about this.

ECONOMIST: Theoretical physics

And unless a radically new technology becomes available, the pursuit of string theory is beyond the pocket of even a transnational effort.

ECONOMIST: The truth is out there. Maybe

The strings predicted by string theory are so small and convoluted that unwrapping them would require energies that have not existed since shortly after the Big Bang. (This is the main reason why string theory remains just a theory.) Dr Arkani-Hamed's loops, however, may be observable with existing equipment.
