My thoughts and theory on this:
Light can be pulled by gravity, so it COULD be pulled to the earth, but our gravity is such that any "bend" in the light would be completely undetectable.
If we had a much higher gravitational pull (or light travelled at a slower pace..) then it *MAY* follow the earths curve, making the surface look almost flat. the gravitational pull however would be such that earth would almost be a black hole.
and Black holes are the proof here- light cannot escape the gravitational pull.
