Einsteins theory of general relativity says that the presence of matter warps the space around it. The more matter there is, the stronger the warp. For really strong distortions of space-time, like black holes, the warping acts like a lens and markedly changes the path of light that passes through it. Such gravitational lenses have been found, and astronomers can use them to study very distant and very faint galaxies.
Join us and see how the combination of a huge galaxy cluster and the observations from two space telescopes enable study of a galaxy whose light would otherwise be unobservable.

The space in self are warped by gravity. Is empty but it's something: we experience three spatial dimensions. The matter and light matches the shape of space.

if space by definition is empty ,how can emptyness be warped.
