Why do we see a gravitational redshift in the spectrum of the sun?
a) spacetime curvature allows red photons of light to escape the sun more easily than blue photons, leading to an apparent redshift. b) because of gravity, the sun is always moving away from us, so we see a redshift. c) time runs slower on the sun than on earth, making lines in the solar spectrum have lower frequency and hence longer wavelength than normal. d) gravity makes light heavy, causing it to appear redder.
