Nathan Rosen - Work With Einstein

Work With Einstein

In 1935 he became Albert Einstein's assistant at The Institute for Advanced Study in Princeton, New Jersey and continued in that position until 1945. While working with Einstein, Rosen pointed out the peculiarities of Einstein’s studies involving entangled wave functions, and, in coordination with Boris Podolsky, a paper was drafted. The paper, entitled “Can quantum-mechanical description of physical reality be considered complete?" labeled these effects the Einstein-Podolsky-Rosen paradox or EPR paradox. Einstein encouraged Rosen to continue his career in physics in Israel thereafter. Einstein and Rosen discovered the mathematical solution for a type of wormhole connecting distant areas in space. Dubbed an Einstein-Rosen bridge, or Schwarzschild Wormhole, the solution was found by merging the mathematical models of a black hole and a white hole (a theoretical black hole moving backward in time), using Einstein’s field equations. Einstein-Rosen Bridges are purely theoretical. It was shown in a 1962 paper by theoretical physicists John A. Wheeler and Robert W. Fuller that these types of wormholes are unstable.
