Note the observable universe has an event horizon 13.8B years in time or 92GLY wide in space which we cannot communicate across. Some speculate the observable universe may also have the mass-energy of a black hole with an event horizon of that size. But the observable universe is not a singularity with all the mass-energy concentrated at a infinitely small "center". So in conclusion the observable universe SOME of the characteristics of being inside a black hole, but not all of them.
