It seems science fact is less attractive than science fiction.
When the apple hit Newton’s head he was able to devise a solution to describe the motion of all planets except one… Mercury. Its orbit just did not work in his theories.
This was perhaps one problems Einstein tried to solve with his Special Relativity (from what I understand this means gravity warped space-time). Mercury's orbit was explained. Perhaps this is an attempt to prove or refine that conclusion.
Me, I would like to learn more about Gravity waves.
