confirmed using GR + spin that black holes yield at least an
internal universe.
Interesting. Wish I could follow this more closely.
I think this is shown by the Penrose diagram of a rotating black
hole, if I remember correctly. I certainly wrote a science fiction
story on that basis once!
Any chance to get a PDF or link?
For the diagram, or the story?
The diagram's here...

Thanks to you and Richard for the technical links, but I was actually
asking for the fiction story you wrote :)
The story is in a notebook in my bedroom. It was written in the
1970s, before the era of PCs.
OK. If you like it, scan it, so that we can share the pleasure. easy
to say, I am a bit lazy myself with the handwritten stuff. I bought a
scanner, but it worked for two days ... The worst is that I continue a
lot the handwriting (on salvia mainly, though).
Thanks again for the links, but my wish above was more in finding time
to read the papers, than to find the papers. As a mathematician, it
takes me a lot of time to understand the math of physicists :)
Best,
Bruno
