And we have one theory, m theory or string theory, suggests that the constants of nature are pegged to fields that can vary across space in time.
我们有一个理论,M理论或弦理论,认为自然界的常数,是钉在“场”里的,它们随时间和空间而变化。
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。
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。
