So a string theory with gravity in anti de Sitter space apparently resolves the black hole information paradox via the adS/CFT correspondence.
I'm wondering: is the anti de Sitter space somehow necessary to string theory with gravity? Or is it just because there's this adS/CFT correspondence.
Also, this anti de Sitter space is 5-dimensional, I think.
The universe is expanding and cosmological spacetime looks like de Sitter space right now, I guess.
Can that 5-D anti de Sitter space be combined with de Sitter space? So that locally it would look like anti de Sitter space and on a large scale like de Sitter space?
thanks
