How is the speed of light, and path of travel, effected in time-space distorted (by say, gravity)?(adsbygoogle = window.adsbygoogle || []).push({});

We know that the sun/earth's gravity distorts time-space.

So when a photon travels from sun to earth....as it nears the earth....

how much length would the photon travel?

Would it be slightly more than the "straight line" (or "un-distorted space-time") distance?

Alternatively

lets assume that if there were no gravity (i.e. assume that sun and earth were mass-less or very light).....and that the photon would travel the distance between the sun and earth in say exactly 8 mins

now with gravity (sun and earth factored in with their actual masses) would the distance be slightly more due to space-time distortion? how much time would the photon now take?
