"Is Einstein still right?"

Readers of this blog know the drill by now: give the points and bet on Big Al.

If you believe that Einstein’s theory is incomplete, then it behooves you to carry out new and ever more precise experiments and observations that may point to additional anomalies and reveal the path forward. This is extremely hard because Einstein’s theory has already been tested to incredible precision over the past half-century using laboratory experiments, measurements of planetary and spacecraft orbits in the Solar System, and observations of pulsars in double-star orbits. Therefore, finding new ways to test the theory is very hard, and coming up with extensions of the theory that predict new observable effects but are not ruled out by previous observations is even harder.
