Hi,
I was wondering if anyone could clarify something for me. I have been reading about the curvature of Spacetime and have come across a few things in articles in conjunction with de Sitter and Anti de Sitter spaces "Negative curvature corresponds to an attractive force" and "Positive background curvature means Universe is expanding at an increasing rate". Could someone clarify if positive matter produces positive or negative curvature and if more rapid expansion does cause negative curvature?
Thanks
