But there is stuff in the universe, so we know it's not Minkowski space.
但是宇宙中是有物质的，所以我们知道宇宙不是明可夫斯基空间。
In particular, we give a characteristic of hyperspheres in a Minkowski space.
特别地，我们给出了闵可夫斯基空间中超球面的一个特征。
Here, Benedetti considers two types of spacetime with quantum group symmetry - a quantum sphere and k-Minkowski spacetime - and calculates their dimensions.
对此，Benedetti考虑到了两种类型的量子群对称性时空——一种是量子球与K-闵可夫斯基时空，另一种是对前一种时空维数的计算时空。
Plasma through the plane to medium vision with massive particles through path minkowski space plane path of the mathematical description of consistent, contain the space and time dimension.
等离子通过异向介质的平面路径与大规模粒子通过闵可夫斯基空间的平面路径的数学描述一致，其中都包含了空间和时间的维度。
Secondly, we investigate the energy density produced by a state vector which is the superposition of three single electron states in the Dirac field in the four-dimensional Minkowski spacetime.
然后，研究了在四维平直时空下三个单粒子态构成的量子态的负能密度。
