## Raum und Zeit [Space and Time], 1909 [FOUR-DIMENSIONAL SPACETIME HYPOTHESIS]

Leipzig: F.W. Vogel, 1909. 1st Edition. Bound first edition of the FIRST PUBLISHED ACCCOUNT OF MINKOWSKI’S SPACETIME HYPOTHESIS “THE NOTION THAT MADE POSSIBLE THE EXPANSION OF THE RELATIVITY THEORY OF EINSTEIN FROM ITS SPECIFIC (1905) TO ITS GENERAL FORM (1916). Minkowski's hypothesis was first presented as a lecture on his theory of four-dimensional spacetime at the 80th Assembly of German Natural Scientists and Physicians in 1908, with this text of the lecture published the following year.

“The technical description of Minkowski’s space-time hypothesis is the four-dimensional space-time continuum” (Printing and the Mind of Man, 401). “In the concept of ‘spacetime,’ space and time are not distinct entities, but are integrated into a four-dimensional spacetime continuum” (History of Physics: The Wenner Collection).

“The impact of Minkowski’s ideas on the twentieth century physics has been so immense that one cannot imagine modern physics without the notion of spacetime. It would hardly be an exaggeration to say that spacetime has been the greatest discovery in physics of all times. The only other discovery that comes close to spacetime is Einstein’s general relativity, which revealed that gravity is a manifestation of the curvature of spacetime. But it was the discovery of spacetime which paved the way for this deep understanding of what gravity really is” (Petkov, p. v).

Einstein had argued that “it was not merely impracticable to measure the earth’s speed through space: the very formulation of the enquiry showed a complete misconception of the nature of the universe. Absolute space and time are not constituents of the real world but metaphysical concepts of the human mind… Minkowski maintained that the separation of time and space is a false conception; that time itself is a dimension, comparable to length, breadth, and height; and that therefore the true conception of reality was constituted by a space-time continuum possessing these four dimensions...

“Minkowski’s hypothesis was in effect a restatement of Einstein’s basic principle in a form that greatly enhanced its plausibility and also introduced important new developments” (PMM). Initially indifferent toward Minkowski’s four-dimensional formulation of his own special relativity, Einstein soon grasped that his own theory of gravity would be implausible absent Minkowski’s hypothesis. “In relativity, time is not an absolute because the rate at which time passes depends on one’s velocity and location within gravitational fields. Distance is also not absolute in special relativity. The concept of spacetime recognizes these relationships by linking time and space. The concept of spacetime was essential to Einstein’s development of general relativity and has since become the standard for describing the physics of space and time” (Wenner).

“In the Minkowski-Einstein universe a geometry conceived in terms of space and not of flat surfaces is essential… No particle in a Euclidean universe moves at such a speed that no greater speed is conceivable. In Minkowski’s universe this is not true.A finite figure of ultimate velocity must be found. This is now conceded to be the speed of light” (PMM). Item #1359
