When you see the light from the sun, there is only pushed away light.
No, the sun emits light and since the sun isn't massive enough to pull the light back the light is going to travel outward. Ofcourse people can observe this light, unlike your light being pushed away from the earth.You still haven't answered where this pushed away light goes to and why no probes have detected it.
Its simply that it is only noticable on light that wasdirected towards the earth.
The light from the sun is invisible unless its directed at the earth? I think you'll find the probes on mars *can* detect light from the sun. Light traveling stright up from the plane (ie away from the sun), is going faster than light going straight down.
So this light is travelling faster than the speed of light? Wheres your measurements you've taken of this light?
