反德西特空间虽然无穷大，却有个位于无穷远的“边界” 。 - For four - dimensional anti - de sitter space , the boundary has two space dimensions and one time dimension
对于四维的反德西特空间来说，边界则是三维的，其中两维是空间，一维是时间。 - In particular , does anything similar hold for a universe like ours in place of the anti - de sitter space
尤其是类似的概念是否在和我们这个世界相似的宇宙中也成立，而不是仅出现在反德西特空间中？ - Just as the boundary of the escher print is a circle , the boundary of four - dimensional anti - de sitter space at any moment in time is a sphere
