Space, time and elementary interactions in relativity
FEB 01, 1969
To express in a unified formalism all the interactions of matter, ranging from the elementary particles to astronomical bodies, we should begin with a simple study of the concepts of Einstein’s space—time.
A REASONABLE COURSE of investigation in fundamental physics should fully exploit Einstein’s approach to the meaning of space—time; it would proceed by exploring, in a unified way, the predictions of generalized equations of general relativity that would encompass in one formalism all of the domains of interaction—from fermis to light years.
