Hi,
in high school I think we all learned that "the path of light is invertible (reversible?)". My interpretation would be that if a ray of light hits a flat mirror at [tex]90^{o}[/tex], it will trace its path exactly back.
Question: does this still hold in the general theory of relativity when space is bent by masses?
