A Spacetime Map of the Universe: Implications for Cosmology

Authors: John A. Gowan

I present a 4-dimensional spacetime map of the cosmos showing our position in it and how we view the universe. We exist on the spacetime edge of the cosmos looking backward in time toward its beginning and "center" as we look outward in every direction in space. As we look deeper into spacetime we look into successively smaller and younger historical eras of our universe, all of which nevertheless surround us completely. Implications for cosmology (including the theory of "inflation") resulting from this (generally unappreciated) perspective are discussed.
