If one moves away from a star closing in on the speed of light, planetary objects slow down. What would they appear as exactly at the speed of light, and would they go in reverse once over that speed?

in a sense everything you go by is moving in reverse....
it is travling behind you and further away

If it was possible to travel faster than the speed of light, you would catch up to and surpass "old" photons which left that star before your trip began. So it would appear that, as you pass these "older" photons, the star and everything you left behind would move in reverse. However, the problem is, in order to see this you have to be facing the opposite direction in which you are traveling. This means the photons will hit the back of your head (or any other optic device) first and never reach your eyes.

As you approach the speed of light, the planetary objects do not in fact slow down. They *appear* to you to slow down, because of time dilation. At an infinitesimal increment from the speed of light, they would appear to be stopped.

Since it is impossible to travel at, or faster than the speed of light, it is equally correct to say that planetary objects would both go in reverse and would not go in reverse at the same time.

Well your question is good. IF. They (the science people) tell us nothing can move faster than light. The Bible tell us nothing is too hard with God. He apparently appears in heaven but at the same instant fills the whole universe!

The most interesting concept about God is that he lives outside time. This means He at the same instant spans eternity. This means he wasn't there last year but He is there last year. He will not be there in 10 years time but he is there in 10 years time.

I am sure He travels faster than light but then He is God!!1

No spoke of speed is ever speedier than gentle. One man or woman transferring west at seventy 5% of the speed of light will see somebody else transferring east at seventy 5% of the speed of light as transferring away at lower than the speed of light, no longer at one and a 1/2 cases the speed of light. that's a measured truth, relativity is only weird and wonderful math that transformations time and distance with speed to make each and each of the calculations trust that measured truth.

Einstein's Information is way too out of date to listen to anymore. Theoretics have changed completely since Albert's time. There is such thing as "Faster than Light" and to prove it look at blackholes! Blackholes are suppermassive stars that have collapsed in on themselves and there is supportive evidence that PROVES there is such thing as "Faster than light. When you look at a black hole there is nothing around it but swirling ionized gasses and Dissappearing Light!!! What can go faster than light? Think about it for a second...hmm...

....GRAVITY. if you have a large enough force that can literally "pull" in light itself, then that light is being pulled by something faster than IT.
