As I said. Both received a Nobel for discovering of the famous binary pulsar, just that. 1) Gravitational waves have been never detected. Everything about pulsar is about indirect tests. 2) Last high precision observations reveals that binary pulsar is better described by non-geometrical theory of gravity which gives the same prediction than GR more a 1% excess cannot be explained using GR.

General Relativity is the result of the work of a number of authors. Main authors were Einstein, Grossman, and Hilbert. Attributing GR to Einstein alone is, of course, historically inacurate. -- http://www.canonicalscience.org/
