Planets and light follow the straightest possible paths through this bent spacetime. Starlight passing the edge of the Sun is bent by about 1.7 arcseconds.
General relativity can’t be the whole truth about gravity. Together with quantum theory, it implies that gravity can’t be measured precisely in tiny regions of space. So the smooth spacetime of general relativity must break down there.
