Multiple Choice
Light is increasingly redshifted near a black hole because:
A) the photons are moving away from us very quickly as they are sucked into the black hole
B) the photons are moving increasingly faster in order to escape the pull of the black hole
C) the photons lose energy because climbing out of the black hole's gravity makes them tired
D) the curvature of spacetime is increasingly stretched near the black hole, which in turn stretches the wavelengths of the photons
E) time is moving increasingly slower as viewed from the observer's frame of reference
