- de Sitter spacetime is curved despite containing no mass-energy, because of a positive cosmological constant. Does it have a foliation into spatially flat hypersurfaces though?
I was just reading about de Sitter space and the following question occurred to me:

Maybe it's just me but I find interesting the question of whether space is curved as well as spacetime. I looked at a few articles on de Sitter spacetime but could not readily find the answer. I was hoping somebody who knows lots about de Sitter spacetimes could tell me.
Thank you.
