Yours is a hideously naive statement; your "fact" is nothing of the kind. Light is an electromagnetic wave, period. If you change the speed of light, you must also change the fundamental electric and magnetic properties of the vacuum. Spacetime curvature doesn't change those properties. Light that approaches a gravitational source gains energy (decreases in wavelength, increases in frequency). Light that goes away from a gravitational source loses energy (increases in wavelength, decreases in frequency). The photons themselves are not measured to speed up or slow down. Light is affected by gravity, but not in the way you believe it is.
