It’s stuck in the universe on the other side of the event horizon, just like you’re stuck in this universe and can’t get back to the other side of the black hole you came through at the Big Bang. Everyone who says I’m wrong can’t explain why the math agrees, and the math and physics of a specifically sized black hole roughly matches the math and physics of the observable universe, where anything passing into the black hole across the event horizon would simply speed up past the speed of light and would not be destroyed. You simply have to understand the math of inside a black hole and turn that infinity sideways so that the multiple dimensions of time become the proper multiple dimensions of space and time in the newly formed universe. Seriously, just do the math and say it’s wrong.
