EINSTEIN, Albert. "Kosmologische Betrachtungen zur allgemeinen Relativitätstheorie." [Offprint from:] Sitzungsberichte der Königlich preussischen Akademie der Wissenschaften, VI. Berlin, 1917.
8o. Original printed wrappers.
FIRST EDITION, OFFPRINT ISSUE. It is in this paper that Einstein introduces an entire field, general relativistic cosmology, and introduces a constant--termed the Cosmological Constant--to describe a universe that is ever expanding. Einstein will later reject this concept as the worst mistake of his life. Nevertheless, discoveries since the year 2000 suggest that we live in a universe that will always expand, and at an ever-increasing rate. Weil 96.
