Is There a Bubble of Vacuum Energy in a Black Hole?

We're saying that the things we're calling black holes are actually bubbles of vacuum energy. They don't explain what this vacuum energy is or where it comes from. But there is a history of people developing these kinds of ideas. People trying to understand how you could have a spinning black hole in an expanding universe. Nobody really knows if it's even possible in Einstein's theory. That leads people to explore other kinds of things. Instead of having a singularity at the heart of it, what if you put a little expanding universe inside the black hole? It might help you match the expanding universe outside the black hole. What they see is an incredible distortion of space. There's no singularity
