Jim, Jim, Jim!

You have turned to insulting a most patient teacher who asks a simple yes/no question.

Do you accept the mathematics of GR as a valid description of the universe or not?

David has pointed out that the mathematics of GR, not a mere interpretation thereof, predicts the existence of gravitational waves just as the mathematics of Maxwell's equations predict the existence of electromagnetic waves.

Answer his question yes or no, or expect a perturbed gadfly to bite your pompous posterior.

This bite of realism brought to you by "Gadfly."
