I have heard about the effects on light when passing a black hole.I know that a black hole has a gravity so high that it sucks light.And that there is a point light orbits a black hole. So I was wondering if there is a point where light gets turned around and flies back into the direction it came from. And we could see the earth as it was thousands of years ago. If of course we had a telescope Capable of looking a distance that big. (please don't mind my English, I'm Dutch)
