Light that looks like it's bending around a star is actually traveling
in a straight line.  The gravity of the star bends space, and the light
traveling in a straight line through curved space, from our vantage
point, looks like it's traveling in a curve.  A black hole's gravity is
so strong that it bends space completely back on itself.  The light
still travels in a straight line, but in that closed geometry it never
escapes to where we can see it.
