Three decades of effort have been expended on string theory, which includes gravity but at the expense of having the universe inelegantly sprout hidden dimensions.

而那个花了三十多年努力的“弦理论”，虽然把引力拉扯进来了，代价是让宇宙加几个不知哪冒出来的维度。

So if OPERA's results hold up, they could provide support for the existence of sterile neutrinos, extra dimensions and perhaps string theory.

因此，如果OPERA的实验结果站得住脚，它们就可以支持惰性中微子、额外维度、也许还有弦理论的存在。

Some string theorists think the extra dimensions of space-time, which are predicted in string theory, may take this shape.

一些弦论理论家认为弦论所预测的时空以外的额外维度，可能就是这个形状。

On the other hand, the good news for physicists is that, if the theory is correct, the loops formed by these extra dimensions, unlike those of standard string theory, will be relatively large.

ECONOMIST: A matter of gravity

Extra dimensions are of interest because string theory, a class of mathematical models based on quantum theory that seeks to describe reality in the most fundamental way, requires that there be at least six of them, maybe more.

The theory also suggests that space has fewer dimensions at very high energies of the kind associated with the early, post-big bang universe.
