I wonder who this 'they' is. I think that you misread.
Everything that exists in the universe exists as space-time. Gravity is how space-time interacts with other space-time.

Space/time is anything but a manifold, in classical physics it is defined as the 4th dimension. Manifolds opearte in the quantum field, such as string theory explains. Gravitational fields operate within the structure of time/space. Gravity is a feeble, virtually undetectable force in the quantum world!

Look up the definition of manifold ... you'll see it's a surface.. in space time, that makes it a 4 dimesional surface
