Prespacetime Journal ("PSTJ," http://www.prespacetime.com) is a publication in which physicists, mathematicians and other learned scholars publish their research results and express their views on the origin, nature and mechanism of spacetime and its possible connection to a prespacetime. It is also a journal where all learned scholars can present their models and experimental results on elemental particles, fundamental forces including gravity and related topics.
