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。

When the string of the mind is properly attuned to the universe then at each point the universal song can awaken its sympathetic vibrations.

当心弦与宇宙万物合拍时，宇宙的歌声时时刻刻都能唤起心灵和谐的共振。

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 recent years some of the brightest theorists have argued that the very presence of humans in the universe indicates which of the many string theories is valid namely, those that allow the universe to exist as observers see it.

ECONOMIST: Theoretical physics

Fox tackles the origins of the current thinking on the beginning of the universe starting way, way back with Plato, and moving her way through Ptolemy, the astronomical duo of Tycho Brahe and Johannes Kepler (did you know that Brahe had his own castle for studying astronomy?), Galileo, Newton, Einstein, and the current state of the Big Bang, String Theory, and alternative theories for the origins of the universe.

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).
