下面的东西参考英文wiki,有数学/物理专业的帮忙解释下
真正的4维空间至少有两种分类
一个是 Euclidean space,纯粹的空间概念
一个是 Minkowski space,时空概念,来自狭义相对论,类似于楼主的说法
Mathematically, the 4-dimensional spatial equivalent of conventional 3-dimensional geometry is the Euclidean 4-space, a 4-dimensional normed vector space with the Euclidean norm. The "length" of a vector f{x} = (p, q, r, s)
上面是用矩阵做的数学定义,具体的 Euclidean space 四维纯空间例子 tesseract 下图的立方体,注意要做2维旋转,本论坛不支持动画
A generalization of the cube to dimensions greater than three is called a “hypercube”, “n-cube” or “measure polytope”. The tesseract is the four-dimensional hypercube, or 4-cube.
Minkowski space 就是3维空间加时间维
上面两个概念是确实存在的学术理论,但也不是真理,不是像1+1=2这样被证明的东西
但是什么灵魂,宗教之类的,纯粹是没边的胡扯
