A Spacetime Map of the Universe: Implications for Cosmology

Authors: John A. Gowan

I present a 4-dimensional spacetime map of the cosmos showing the position from which we view the universe. We exist on the spacetime edge of the cosmos looking (in every direction) backward in time toward its beginning and "center" (the "Big Bang"). As we look deeper into spacetime we see successively smaller and younger historical eras of our universe, all of which nevertheless surround us completely. Implications for cosmology (including the theory of "inflation", the "horizon problem", and the "flatness problem") resulting from this (generally unappreciated) perspective are discussed. The map predicts a "Hubble constant" (expansion rate) in excellent agreement with the currently accepted value.
