Einstein Refutes Attack on Theory: In a Joint Rebuttal with Dr. Rosen He Shows Error in Silberstein Challenge. Discoverer of Relativity Says Opponent's ‘Mass Centers' Have No Reality" in New York Times, March 7, 1936 [EINSTEIN & ROSEN REFUTE SILBERSTEIN'S CONTROVERSIAL ASSERTIONS & CHALLENGE]

New York: New York Times, 1936. 1st Edition. First edition of the March 7, 1936 issue of the New York Times, complete with "Certificate of Authentication" by the Historic Newspaper Archives. The certificate is #379913; it is signed and includes the seal of the archive.

As the title implies, this article reports Einstein and Rosen's refutation of Ludwik Silberstein's public skepticism of Einstein's results, calculations, and processes of verification. " In 1935, following a controversial debate with Einstein, Silberstein published a solution of Einstein's field equations that appeared to describe a static, axisymmetric metric with only two point singularities representing two point masses. Such a solution clearly violates our understanding of gravity: with nothing to support them and no kinetic energy to hold them apart, the two masses should fall towards each other due to their mutual gravity, in contrast with the static nature of Silberstein's solution. This led Silberstein to claim that Einstein's theory was flawed, in need of a revision" (Wikipedia). Einstein and Rosen joint rebuttal is presented here, and together, they point out a critical flaw in Silberstein's reasoning.

In the end, "Einstein was correct and Silberstein was wrong: as we know today, all solutions to Weyl's family of axisymmetric metrics, of which Silberstein's is one example, necessarily contain singular structures ("struts", "ropes", or "membranes") that are responsible for holding masses against the attractive force of gravity in a static configuration" (ibid). CONDITION: Historic Newspaper Archives (see above) has placed the issue in archival plastic and then into an Archive snap close bag. (see photo) By any measure, this complete issue appears in very good condition.
