Abstract
One wrong assumption may be our belief that we live in a unique spacetime continuum. The Multispace Model advances the hypothesis that the universe is a multispace world, filled with countless independent and overlapping spaces. The model is based on the author's discovery of a 3D Space-Time Diagram (3DSD) of special relativity, which he introduces to the reader following a series of hypothetical hints left by Minkowski. The author wouldn't tell if the famous mathematician really left these hints for posterity. It's up to you to decide. The Multispace Model introduces the reader to several hypotheses. Reference frames of special relativity are independent physical spaces, hypothesis that confirms Minkowski's 1908 declaration that the world is composed of an infinite number of spaces. The model also leads us believe that space and time may not be the most basic constituents of reality. Some spaces, like those holding fundamental particles, are relativistically orthogonal to the space of the universe and therefore invisible to us. This prediction explains quantum spaces as real frameworks embedded in the universe, but physically separated from it. Spaces holding nested spaces (think of an atom) are visible, while gravity appears to be a force not of attraction but of repulsion, a cosmic pressure.
