From what I have gathered from another thread, the Ande-Sitter Spacetime incorperates a negative cosmological constant. Then the universe would constantly be contracting. I am sure I am missing something here. Does the Ande-Siter spacetime incorperate a static universe as well?

But here is Ed Witten's thoughts link:http://online.itp.ucsb.edu/online/st...ten/oh/04.html
I believe this is an original paper of above:http://www.worldscinet.com/ijmpa/16/...X01004451.html

I never heard of Ande-Sitter Spacetime. I guess you mean anti-de Sitter spacetime (AdS). .
It is an empty universe with negative cosmological constant.
AdS spaces are the most symmetric solutions of the Einstein equations (with lambda<0).
