In general relativity, time is considered a dimension like height, width and depth, creating a four dimensional universe called space-time.
在广义相对论中，时间被看作和长宽高一样的维度，并与它们构成了一个四维宇宙—被称作时空。
For those keen to know more: the computations involve "envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows.
一点额外的话给那些想要知道更多的人：这个计算包括 “想象一下，时间和空间将成为水晶方格似的四维空间的一部分，不连续的点在空间纵横其间。”
Its description of time travel in a four-dimensional universe presaged the cottage industry in theoretical space-time machines that has sprung up among physicists in recent decades.
近几十年中物理学家们争先恐后进行理论上时光机器的研究，就证明《时间机器》关于四维宇宙中时光旅行的描写极具预见性。
Just as loop quantum gravity breaks up space into tiny "building blocks", CDT assumes that space-time is split into tiny building blocks - this time, four-dimensional chunks called pentachorons.
只不过圈量子引力理论把空间分为微小的“构建模块”，而CDT假设空间-时间不是分成微小的构建模块—而是叫做pentachorons的四维的小块。
We want everyone to walk into Vera Mitter, have entered a four-dimensional space-time surprise feelings.
我们希望每一个走进维拉米特的人，都有进入一个四维时空的惊喜感受。
The four dimensional space, means that the mankind the substance space( namely three dimensional space ) of the concrete activity, plus one more consciousness measurement ( time factor).
四维空间，是指在人类具体活动的实质空间（即三维空间）之上，再加上一个瞬间取向的知觉量度（即时间因素）。
At the same time, there is no brand on the "Introduction" and "trade", "cite", "only" four-dimensional space to conduct and thought by the rich and recycling, it also can not brand.
同时没有把品牌放在“言”、“行”、“举”、“止”的四维空间里逐个进行行为和思想上的丰富和再造，那也做不了品牌。
The four-dimensional space-time of special relativity is augmented with a fifth dimension to take into account the gauge transformation of the electromagnetic potentials.
本文从电磁势的规范变换出发引入第五维空间和一个新场量。
For now, people only know about the one-dimensional time, two-dimensional, three-dimensional space, and Einstein, the reference to "four-dimensional space-time" concept.
