The Particle Problem in the General Theory of Relativity. [Offprint from] The Physical Review, Volume 48, Number 1.
Lancaster, PA: The Lancaster Press for The American Physical Society, July 1, 1935 - 5 page offprint. Original green wrappers printed in black. Wrappers a little rubbed and marked, corners creased, small dark scuff to upper wrapper. A very good copy. Offprint of this important paper predicting the existence of wormholes, also known as Einstein-Rosen bridges. "In the last decades of his life, Albert Einstein tried endlessly to unify electromagnetism with his own theory of gravity, general relativity. These efforts are mostly now regarded as quixotic, but a short proposal written in 1935 with a colleague has survived in unlikely fashion as the source of science-fiction ideas for speeding across the universe by means of 'wormholes' through spacetime. From the modern perspective, the paper also illustrates how general relativity posed mathematical and conceptual difficulties that foxed even its creator. Einstein and Nathan Rosen, both at the Institute for Advanced Study in Princeton, wanted to rid physics of singularities–points where mathematical quantities become infinite or otherwise ill-defined–such as the concept of a particle that has all its mass concentrated into an infinitely small geometrical point They imagined a path tracing radially inward. Instead of trying to cross the imaginary spherical shell at the singular radius and proceeding down to the center, Einstein and Rosen showed how to match the path onto another track that emerges outward again–but into a separate section of spacetime. Imagine funnel shapes pulled out of two adjacent rubber sheets and connected at their necks, providing a continuous, tube-shaped path from one surface to the other. This construction makes a smooth connection or bridge between two distinct pieces of spacetime" (Lindley, Focus: The Birth of Wormholes, The Physical Review, March 25, 2005). Weil 196.
