Theoretical physicists have thought long and hard about what goes on inside black holes and their conclusions are mind-bending to say the least.
理论物理学家已经对黑洞内究竟发生了什么探索良久，然而他们的结论可以说实在令人费解。
Whether the singularity is an actual point of infinite density or just a mathematical inadequacy of GR is unclear, as the equations of GR break down inside black holes.
我们无从得知奇点是真实的存在还是广义相对论的数学缺陷，因为广义相对论方程在黑洞中失效。
Sadly, there is no point in us looking for other universes inside black holes.
可惜的是，我们无法在黑洞中寻找其他的宇宙。
Just as the initial singularity at the start of the universe may have had only one possible state, so it is possible that the final singularities inside black holes have a unique state.
正如同宇宙的初始奇异点可能只有一种状态，所以黑洞内部的最终奇异点也可能只有唯一的状态。
