The jury hasn't even been seated yet!

Like Newton's classical mechanics, I doubt that general relativity

Suggest readers read Overbye's article at
http://www.nytimes.com/2010/07/13/science/13gravity.html

Science still requires empirical testing. If an idea can't be tested,
it isn't science, but philosophy.
